Hello everybody, Andrew Mayeski here with Dental L. So let's talk about mobile hygiene, even just as an independent dental hygienist. Is it worth it in the sense as do we make any money? I get this question all the time, even from dentists that I have known for years. Ask me, you know, well, do you actually make any money because you have all of these costs kind of the same as us?  It's still you putting your time into it. Do you actually make any money at the end of the day? So let me talk to you guys a little bit because that is a great question. And this is where you have to be careful because number one, you have to think about you will likely need to take out a business loan. Even if you have a mobile practice, yes, you don't have as many expenses as your own actual office, but you still have to pay for your instruments. You still have to pay for your supplies, your car maintenance, you have to pay for that. You have to pay for your uniform. You have to pay for your piezo, your cabotron. If you decide to have a sterilizer in your own house, that is something that's a big expense. Trust me, if you buy high-speed handpieces as a restorative hygienist, if you buy slow-speed handpieces, just everything has a cost. I can't even think of everything at the moment, but you're always buying something, right? But that's, and that just kind of goes into doing business. A practice management software system will cost you a fortune. It's crazy. But after day one, you will not want any paper charts. Trust me, I tried that to save money. Yes, I did. But you're just on the go and it's just messy. In my opinion, it's just messy. Maybe you have a better plan, but I tried the whole paper charting thing and I didn't like it right away. I did not want to spend 5,000 plus on a practice management software system, but you kind of have to because when you're doing probing, charting, the odonogram, it's just a big mess to have to try to use paper or do half computer, half paper. That's kind of a mess in itself too. But all in all, do you make any money at the end of the day? And I would like to say yes. We would not be doing it if we didn't make enough money, if we're smart at it. Are we all millionaires? No, but we do make money. Now I've only been doing this for less than a year, so I can't speak to those who have been doing it for longer, but another thing that I notice also is there's a lot of mobile, even any independent dental hygienists, a lot of them are starting to sell their practice, meaning they're selling everything they purchased. Their sterilizer, their piezo, their supplies, their equipment, everything. I'm seeing that a lot lately. So if I was just getting into this, that would concern me because I'd be thinking, okay, why is everybody selling their equipment? Good for me, because I can buy used, but this can't be a good thing, right? Everybody's selling it. But let me tell you something, you guys. I am very, very busy. I have been doing this for less than a year and I have now got to the point where it's a good problem to have, but I have trouble finding time to see patients because I am that busy. Mind you, I do still work at a dental office two or three days a week, so I don't see patients of my own on those days. So that just kind of limits me to a couple of days a week plus the weekend. So I have not had a weekend to myself since I started the practice, but to me, that's a good problem to have. So yes, I'm making money because otherwise without seeing those patients, I would just be at home. Yes, taking it easy, taking a day off, but I would not be making money, right? I don't see it as kind of making money right now because I'm paying off the business loan to be perfectly honest with you, but the most important thing to say, and this is true, I know it sounds cliche, but it's not about the money. I don't think about money honestly for a second until it's time for the patient to pay me and then I go, okay, how will you be paying for that today, like cash, credit card, e-transfer, that's the only time that I think about the money because I love seeing my patients. It's the nicest thing ever to be able to see your own patients do your own thing. It just makes you, at least it makes me feel good that I'm an expert and I can do that. I just love it. So if I was working at a dental office, depending on where you work, you might make $30 per hour, $40, $45 or more, but when I see my own patients, I make more, obviously, right? For a cleaning, I charge about $150. For a child, it's probably about 65 to 100 depending on how much plaque and charter they have. If I do an exam, that is $30, so everything on top of that, it adds up. So do we make money? Of course we do, but we do have expenses too. Like I probably order from my dental supply companies at least every month because I need more of something. Whether it be toothbrushes, I just ordered some more toothpaste the other day. I ordered some micro brushes the other day. I had to order some more cassettes. I had to order some more instruments because I didn't order a lot to begin with so I wanted to see how many patients I would have. I was seeing maybe one patient a week. That changed to two patients a week and now I'm seeing about two or three patients a day. And no, that may not seem like a lot to you, but I am mobile, so I go from place to place. So two or three patients a day is enough. Actually, the other day I saw six patients a day but two different locations, but that was awesome. But I wasn't even tired afterwards, which was interesting to me. I thought that I would be exhausted. When I work at the dental office for like four hours only, I'm exhausted. Yet when I do my own thing for eight hours, I come home, I'm pumped up. I'm just so excited that I was able to see my own patients. So yes, so everybody's question is always about the money. But once you get started, you will just love it so much.  If you're charging say $60 per cleaning because you wanna stay competitive, you're really not gonna make any money at the end of the day because you have to counter in all of your supplies. If your patients are paying you the difference of what insurance isn't covering, then you have to do all of the paperwork to send everything through to insurance. So that will eat up a lot of your time. So you should charge accordingly. You know, like don't charge people $60 here and there for a cleaning and do not just say, oh, well, you know, we don't have to do an exam. Let's just do a cleaning for you since you don't have a lot of money. I'll only charge you $60, you know. So be careful with that. Charge accordingly. Go by the fee guy. There are a lot of hygienists out there that are charging a lot less because they feel they have to be competitive. But people are not going to come to you. They're not, I mean, they might actually sorry. They probably will. But at the end of the day, you will be exhausted. You will have made no money because you have to pay for all of those expenses. I'm not saying though, charge like $300 per cleaning either. Like don't go crazy, but go by the fee guide. If you guys need help, I am more than happy to help you. This is something that I am so passionate about. I just love it. I see a lot of seniors in nursing homes and like that just makes me so happy. I've seen a lot of kids lately who are like the age two, three, four, or five that have not been able to go to the dental office before because they were just so nervous, so anxious. But me seeing them in their own home, they were fine. I kind of like, I would say to the parents often like is this your son who you were saying had an anxiety attack pretty much. The last time they went to the dentist and the parents are kind of like, yeah, he's fine with you. I'm kind of embarrassed. I can't believe he's doing so well, but then they're so happy that he did so well but that they will keep calling me. Still make sure they go to the dental office for a checkup and x-rays, but let them know you are more than happy to see them for everything else. So again, I will turn back here. Do you make money? Yes, 100%, but you have to be smart about it. If you're taking out a business loan it might take you longer technically. That's the best thing ever to work for yourself. Trust me, you will pay a lot of taxes. You will be in that self-employed area, which is a pain. I talk about that more come tax time but obviously I've been doing it now. I have owned my own businesses for 14 years. If I'm still doing it, if I can still do it you guys you can do it too. So thank you for watching. Any questions, let me know and I'll see you guys in the next one.


I'm Jörg Steppens from the Barriers Projects and I'd like to show you some methods to interact with barriers. I assume this talk makes most sense for people who are already using barriers or a regular. I hope you're all using it. We will see. Then I will start with a short overview about barriers and then I show different interaction methods. One way to interact with the system is to configure it. I will handle this shortly. The other thing I guess you are more interested in is runtime control of barriers and the other way around things that get triggered by barriers afterwards. How does a barrier infrastructure look like? You have a central director located which keeps all the data. It controls all your backup environment and stores its information in a database. You have the storage daemons which you have one or more multiple storage daemons each with one or multiple storage devices attached. This is where your backup data is getting stored. You have your file daemons or your lines installed on the different machines that you want to backup. You can interact with the director during runtime through the barriers-director-console interface. This is used by command line tool or web interface or some web tools. This is the same just with newer lines. There can also be some plugins like VMware, MSSQL, NNP, cluster, etc. Compuration file. Compuration is handled in resource. The director configuration consists of a director resource, a catalog resource, how to connect to the database. Your lines, the file sets, so the data gets back up, your drops, who is scheduled to storage. As an example, I put in here the drop resource. Each resource got a name. In this case, backup Barrios FD from type backup, level incremental, and then it references to other resources. So it references to the client Barrios FD resource. It refers to the file sets, Linux all resource, to the schedule, and so on to this different pool. And it is enabled, so you can also disable it. I missed some lines here. If you're not sure what you can type in here and are not willing to read the documentation, you can always ask the demons itself. So, for example, the director Barrios director minus XS, like export schema, will show you all available derivatives as you can configure. If you change a configuration on the director, you can reload the director. So it's then immediately working for storage demon and pile demon. You have to restart the demons. I hope this has been everything on this slide, but I guess so. Confuration can be quite large, but it's relatively straightforward, and there are modules available for individual chef puppets, so I'm not aware of. So far for the documentation. Confuration, sorry. So runtime control of Barrios. You can connect to your director. He has a D-console command that you would like to handle this on the command line. Type in D-console. It opens up a TCP connection to your Barrios director. Authenticates after this gets you an interactive prompt that you can type in your commands. The set, you get a list of all available commands. But you're not limited to interactive reuse. You can also pipe in some commands in, and then they will be executed, and so your designs will be listed here to standard out. So there are quite a number of scripts that just use this simple interface. There are some helper functions inside of D-console to generate, to write that script. Like, for example, these are the so-called add commands. So you can redirect the output directly to another file, and also handle this part of, this command should be outputted to this file, and if you have another output, then the rest will be outputted to another file. At this point, you can do the same as input for commands, or some other commands are available. Most commands have also the parameter yes, which says, don't ask me any questions, just do it. So confirm, immediately confirm, and if you have missed some parameter, then the command will not start. Rate is also important, rate until the job is finished, or in this case, until all jobs are finished. As said, you have, this uses the direct-console interface, and this can be accessed by D-console, which we have seen right now. There's also a Python module, Python Barrios to access this. So the Barrios web UI is the screenshot of it here. This uses the same connection, this is written in PHP, so if you have programmed something in PHP, you can reuse part of the code, and Q3-based interface we, but also uses the same interface. But this is much as deprecated across the whole thing you need. This is implemented in Barrios web UI. You can have it wherever you like, because you just use the control interface, and you can connect to it. In all ways, you will connect to it via TCP, so it can be on any system. Yeah, sure. Yes. Sure, but therefore I have to say, mostly it's easier to SSH to the machine, and then use the decontrol part, and also use it remotely. This is, for example, done on some clients. If you want to give them specific access to trigger its own job or something like this, then you can have it decontrol locally installed, limit the access rights, and use it from the client. Also, cataloged database can also be on other systems. Okay, I've talked about the control interface. You should be aware that there are different type of controls, so called default console or root console, which gives you access to all the sources available in the director. This is normally the console used when you just type in decontrol. So the default configuration, this is the absolute console. The other console is the name console or restrict console, and there, to use this, you have to define ACS for this console. So in this case, we have a console, and we're able to name user one, provide the password, in this case, secrets, and allow the user one to execute all commands except of the need commands. And only access data from the My Catalog database, which is the default database, so it's probably all, but you can limit it. And only to the clients, client one and client two, and all these words are regular expressions. So here in this case, Fileset, all Filesets starting with the name Linux and then string job IDs also. If you don't specify SEL for some resource, you don't have access to it. So you have to specify it and provide all or some things that you want to assign to it. I want to do some of the important commands of various help. It's always important to get the list of all commands available. If you also want to know the parameters, you type in height and then type help and then the command name with these 30 parameters. For one-time information of your different components, you can ask status, status director, so your information from the director, or you can ask status of one of your storage systems that's attached to it. Or if this is a tape library, then you can ask what volumes are assigned in what slots or ask the status of different clients. You can also ask when this scheduler has planned to execute this specific drops. If you don't specify a drop name here, then you will see get a list of all drops. Or otherwise, you can see one banner drop on a specific drop. This plan to get started. The list command is to retrieve information from the catalog, from the data base. You have two versions, the normal list and the long list, which provides you more information. And you can ask about information about your backups, your clients, height sets, and so on. For example, if you're interested what drops are stored on volume full one, then you just ask, list the drops that are stored on volume full one. Or the other way around, if you're interested, where the data from your drop one to three is stored on what media and you ask for the drop media from this drop ID. Or if you want to get the information you normally see at messages, you can also ask for those messages that have been created during the drop, as the drop did run. This drops last is quite important, I think. If you want to get a quick overview about the status of your drops, then you can type this command and it will show you the last one of all your drops. So normally, if you don't do this, then you maybe just get all drops from the last 24 hours or something like this. But with this, you also get dropped that didn't run even for a longer period of time. But sometimes confuses people on the mailing list is, for example, if you modify or add a file set and then restart your director and then make lists file set, then you will not see it. Because these data is first synchronized to the database and there has been a drop one that uses this file set. Same with slides. This slide will only show all the slides. So we have a drop did run for this slide. So if you have changed your configuration and want to verify that the director is aware of this, you can use the show command which shows your configuration. You can also ask for specific resources in here. Yes. Yeah, and then you have commands to execute jobs like backup jobs, restore jobs or wait for a job to be finished. A small example to put this together is let's say you have already installed your client's file demon on a new system and want to configure it on the director. You can use the configure ads clients, give it a name, give it a address and give it a password. This command will complain if you have missed some required parameters or if you have put in invalid data. Otherwise, it creates a resource file, a configuration file for the new client and immediately loads it. So you can directly start to use it and check if it's really working. This starts as client and then client name. The same you can do with jobs. So you create your jobs and after these two commands, three commands, you can respond to the job. No, not here. Not if you use this command, then the director creates it automatically. You can also specify all these specific parameters, but if it's a common approach of them, you only have to expand by hand. Yes. It will create a configuration file for you and immediately loads it. That's one of the advantages. In this case, it also creates part of the configuration file that needs on the client. So if you look the other way, once you first add it here, then it has also director export directory and you can copy it over to the client and you start it. No, not with this because you have not the knowledge about this. You want to add some scripts that had to use this, but they haven't done so. For Windows, we have the installer and this has silent install options that you can use to configure it. Also with the director, with the password and things like this, you also provide Opsi packages for the Opsi because Windows management, software management system Opsi, so you can integrate it in your Opsi environment, which you hopefully have and then install it and configure it. This is all things that work well, sometimes they don't, so you can also enable debug during runtime. You do this with set debug, specify the level, 100 is a good starting volume. You specify that it should log to a log file and adding temp, temp is also usable and then what components should have the debug enabled, in this case the director, you choose the storage, what this is. You can't specify to what file, in what file the log file will be generated. However, if you discommand, it will write you the file where it's locked to. This is not a big deal on Linux because it offers in this directory, but on Windows you are glad because depending on the Windows version, to this difference log files. This has been now all about the normal commands. You have also the special dot commands and they have been intended for non-interactive use, but if you're waiting for it, then you might want to use them. You will not see them with the help command, but if you use the dot help command, you will also see these dot commands. For example, dot SQL, you should be able to get all the information you require by the list command, but if this is not the case, you can also specify arbitrary SQL commands to execute. Of course, you could also directly go connect to the database, but here you have already the authentication to the database and don't know what type of database you're using. Now it's getting interesting. The normal output from the v-control is in rp-mode 0, meaning rp-mode disabled. So it's intended to be human readable and it's quite okay. I guess for that some time ago, p-mode 1 has been introduced. There's a reason why we haven't used this anymore, but we introduced ap-mode 2 with output data in JSON formats to be better usable by other programs. So as an example, let me start on top. In ap-mode 0, list-drop 1, you're getting this table nicely formatted and gets the information in there. This ap-mode 1, the declaration is stripped, the first part is stripped and I'm not sure what else has changed, but unfortunately this is not really consistent between the different commands. This ap-mode JSON is the same command. You're getting a dictionary named result and insights because we asked for jobs. You're getting an array of jobs. This is the information as the fields are called. We already tried to mimic JSON ap-c 2.0 format because we have to use some format and maybe then it gets easier to extend it someday to a JSON ap-c server. Yeah, how to use this? For this you could use Python variables. Python variables is something like the deconsole, so it first connects to the director, but there's also a sub-module for JSON, so you can handle the JSON data immediately. You can also directly connect to the storage daemon or file daemon, but they don't have... Yeah, they only provide limited commands that you can use. So as the same example as before, you first have to prepare your password, you import the various BSOB class, prepare your password, then use the director-console-json class, connect to this address with these users and this password, and then you call the command that they are issued before and the humidity gets returned a Python structure with the data encoded. Also not the result text, just a re-result. If there is an error, then you get an exception, so this is quite usable to create your own scripts. If you're doing backups, you probably care about the files and I will now show some methods to access data from files. So even before you really did run a backup job, you can call estimate, listing, and get in return, so then the director will connect to the client and this will return all the files that would get back up if this job would run. If you have really run this job, then you can, with list files of this job ID, you get the list of the files and directory that are back up by this job, but without extra information, so start information and so on. If you use the restore command, say the last backup from this system, then it will generate a virtual file tree and will give you a new prompt and then you can use dir or ls or cd command to walk through your backup data. If the directory is not really included in the backup, but only this because it's the parent directory, then the values here are all zero, like in this case, but here you also got the real backup data from your files, you can mark the files, say done, and then these will be restored. This is fine, but if you really want to write the script to interact with your file data, then this is not enough. For this, you have to use the BVSS API. This is described in the developer guide and it looks quite nice, as you see. You first have to update the cache for the drop ID you're careful and then ask where does this backup start. So BVSS Ls directory is from this drop ID with an empty pass. You'll get root directory in return. This root directory has pass ID three and other values are set to zero. And AAAA means this is all also zero because what you see here is serialized form of the start field normally. This is done in this way, and stored in this way to be more flexible about the database, about different lines, but it's not really handleable. But okay, you now know that your slash directory is at pass ID three. You'll get the directories of pass ID three. Then you'll see, oh, there's a user directory still with no information, but it's got the pass ID two. And then you look for the directories in pass ID two. Then you'll see, oh, this is really something because here are some information and the user sbin directory is in pass ID one and there are no further sub directories, but you can list the files that are in this directory. So you need BVSS if you want to ask various directories for specific directories. Yeah, I say that's not really easy, but this is the way that and also the web UI restore browser did work and use the sub commands because they can't work with the list of all files because they can be quite, quite a many. Oh yeah, in JSON format, you can at least read the data. Yeah, if you want to, but it doesn't help too much. Another way to access this is using Barrios Fuse. So a Fuse file system based on Python Barrios, JSON mode, and if you mount this, this will connect to your director. And in this directory, you mount it to Barrios FS. For example, you get directories for clients, for jobs, for pools, for volumes, and then you can list, for example, the jobs running directory and you will see, okay, currently there's one job running, has this job ID, has the name Gonzo, client Gonzo FD, level is full on status is running because otherwise it wouldn't be in this directory. You can not only ask for running jobs, but you can also ask for all the jobs for client Ting FD and then you will see, let's call it to here, you have on the 20th January, you have a job with this job ID for the name Ting, client Ting FD, level full status, terminated successfully, so this is good. And the day before, you have a similar job, which is incremental. I guess they both started at the same time, you see the full job ends quite later, two hours later, and so on, and here on the 70th January, you get a job that it failed. You not only see the job, you can also go to the directory and then get access to the job block, for example, or the info, which is the information you would get from this job ID of this job and the data, you can descend to the data directory and then you will see all the metadata or all the files that you have back up in your backup job. Of course, you can't access them there because you only, you haven't done a restore, you just look at the metadata that is stored at the directory in the database, but you get the information, you get the metadata, the file change date and so on, and you can use your normal UNIX tools like finds, for example, to find all the files that are larger than 100 megabytes. Incremental will only show only this specific job. You can handle this otherwise, this is just really shallow Python code with list jobs and list files and so on. If you want to have other features just, it will be few lines of code, three or four or something like this. You not only can see the jobs of specific clients, you can also get a list of your pools and your volumes in your pools, then you can immediately see we have this always incremental full volume that is in status full, so we have written this amount of bytes to this volume and it's in read-only mode because, yeah, because it's full. And here on this other volume, you see it's an append mode, so you can still write data to it and therefore it's in read-writes. It's last time data is written to it, it has been written to January. Again, you can change to the directory of a volume, you get some extra information and also drops so you can descend to a volume, to a specific volume and then the jobs and you will see all the jobs that are back up on this volume and in this job you can change to the directories in there and get the files that are back up with this job. So quite useful and you can write your normal Unix tools to script to retrieve some information. It's not the most efficient way to get the data but, yeah, it's quite comfortable. Okay, now we want to care about specific problems and writing script for this. For example, you have your various backup environment and you backup all your servers and everything works fine but your servers are always there so you can have a fixed scheduling for them and backup the data. But now I think you have your coworkers with their laptops and they are sometimes in the office, sometimes not and maybe you have dynamic APIs and so it's complicated to get time when you can backup them. So how to solve this? With this short script I can say and it works like it gets a list of all no, I have to start otherwise. We use the client in a connection so in this case not the director connects to the client but the client is configured to direct connects to the director and the director is then aware of all the clients that did the connection to it and have the connection and if there's a job for the client it will reuse this connection. You get the information with status director and look at the field connected client connection and you only care about the name of the client. Then you loop through all the connected clients. You have the trigger function you can call them by a call for example every hour or every minute as you like. You get all the connected clients you loop through the client so guess a job name associated with the client so if your client is called client one you look for a job backup of client one and if this job exists you check if there is a job for this client in the last 24 hours so if there is no job for this client then you just execute one the job name that you have there yes to confirm it and in result you get a job ID from the newly configured job and you can just print it out so with this short script you can solve the problem with your mobile clients that are sometimes at the office sometimes not just by running this periodically checking the clients that are connected and starting a job if no job exists for the last 24 hours so I have how much time left 50 minutes oh 20 minutes okay then I go no I don't go through this because it's not all on the slide if you have a question about pooling volumes and how to automate this in specific case ask me after this talk oh is that the question? yes no no this is for the time that the clients are back in your office connect to the director which is also located in the office and then you know that your clients are there and then you trigger the backup okay now the other way around things getting triggered by various for this you got one script you got quite flexible one script either you can call with a job a command on the console itself so you see various direct barriers commands you have options like they should only run if the job has succeeded or only if the job has failed and you can specify when they should run before a job after the job I guess one of the set on the one on failure only works with after the job or on windows after VSS something like this you can also execute arbitrary system commands with a command one script and then you have additional options if this command should be executed on the director or on that line where the backup runs and if the job should fail if the system command fails some examples for example if you want to create a virtual pool backup from your existing backups and store it somewhere else to an archive pool but don't want that this newly generated virtual pool is again used as a base for the next virtual pool then what you can do is create your virtual pool store it in the archive pool but after you have done so update the job ID because you know the current job ID where it is variable and change the type from backup to archive similar to backup drops they are not used internally for any other actions so you can just run this this is a console command you can also type it in the B console but you can integrate it with your job and it should run on the server and it should not run if this job before has failed no, not the same no what other drops are available are admin drops normally you get backup drops or restore drops and this admin drop you don't do any actual backup you just use this to run some commands and in this case after the backup of your own system you optimize the database which can be an advantage if you are using Postgres so do onto backups but just use this as a kind of con but we got my other things relax and recover some of you have heard a few are using this or have heard the talks before relax and recover is a disaster recovery environment for linux which works quite well it works in two steps once it creates a rescue image from your current running system it creates a rescue image and you can boot with this rescue image for the system second step itself could do backup but it can also integrate other backup solutions and thankfully varios is also part of this and a minimized way and quite comfortable way to integrate it with varios is normally you got the question ok, when my system broke I need my rescue system so I should be able to have a recent rescue system and then to create it and where to store it because normally you don't want to store it on your local system we have options to store it on NFS and things like this but we are a backup solution so this approach just creates this regularly on every full backup and stores them locally on our own file system because our full file system is back up to the backup server and if you really require it you can extract it from our normal backup and then we store it to another machine where a CD burner or a USB drive is attached we can put it on there and then we have the rescue image we can place it in the same server with the replaced artist and restore our system we do so with the one before script so before we actually do the backup we run on the client disk command this is a shell script this has one parameter this is the backup level so full differential or incremental we only execute this on full because if you would do this in incremental then every incremental have an additional size of 50 or 60 megabytes which you don't want but on your full backup with whatever 2 gigabytes you use 50 megabytes more or less are not really important and it's important to create this rescue image regularly because it integrates your current kernel, your current network configuration your kernel, your current hardest layout so if you don't do this regularly you might run into problems because if your rescue system is one year old so you can only get back to the status from your one year old system so again, something is missing on the slides what I would show you if the scheme has been larger you then have the b-console you type in restore of let me think control-minus control-minus is also an option hey, thanks ok that's what you have to type restore from the current backup of Client, you care about, Client FD1 extracts the file valyp-rear output-rear-barrier.iso this is the default location valyp-rear and restored to some other system which has CD burner attached and use this special restore job just we don't make the restore in the valyp-rear output location, but in the temp-direct you have some other directory you want to use so with this you have your normal backup drops and yeah, and your rear directly integrated with this it requires you, right? no, it doesn't require it, it offers you to restore on NFS, but it also offers different methods like maybe also copying Zumba for sure and a lot of other possibilities I think, yeah, so that will just boot up the ISO and then when you have the recovery system up then you restore the file from yes, so the rear-barriers integration is that rear you can configure your rear barriers and then in the rescue image creates, uses the kernel your network setup, your disk layout, but also copies all the back-barriers tools you have installed on the system, on your rescue system so it boots up and has the same file deamon available that you have on your running system and with this it restores just your data from your normal backup and that will automatically be already into the recovery ISO just as this one line back up barriers, something like this and this is all they would be in the boot command line no, this is in the configuration, we are local.conf, but it's just one line in the configuration so it's really easy to handle and really powerful yes, for sure okay, then this is about scripts, now we let's say two slides about plugins barriers can be extended by plugins for the director, storage deamon or file deamon with this you give that to specific events you care about on the file deamon plugins, normally you use them to backup specific data like a database, virtual machines or something like this plugins on the storage deamon are normally made for rewrite data like on the fly compressed data that's coming in normally this is done on the client but if your client is not that powerful but your storage server is then you can also make the compression there or SCSI crypto to use crypto tapes like this to give some status information or for the director this is normally if you write a plugin there then you do this for status information and the shortest possible plugin is something like this you have to import the barriers class for the director and then you have to overwrite the init function then you register for the events you care about, in this case we only care for the event which opted end, then you have to overwrite the handle plugin event function when this is called it's called with a specific event we check for this event this case it should always be event drop end because we only register for this but we check nevertheless then we retrieve some other information like what client the dropped it run, have there been errors how many bytes, how many files, how many bytes have been transferred we format that in some other way and then we send it to a singer or a graphite or whatever you use for monitoring or for visualizing your backup system or your environment so I'm mostly done just roadmap for the upcoming release for the things that's important for integration is the Python Barrios is currently available at the Barrios concept repository but will be moved to Barrios core repository in the next major release the Barrios web UI is actively developed by Frank over there and it will continue to be enhanced and therefore we also will extend to the vector for to provide more information yeah this part about media handling and optimizing this for this storage I skipped so I don't have, it's not so important what I missed here it's a roadmap we have seen here the console connection where you specify user and the password we have received pull requests for adding PEMP support which has quite some implication but we want to put work on this and get this integrated for we plan to integrate this also for 17.2 so you can directly authenticate your adapt directly or whatever you like okay now we got time for questions no questions I'm done good oh okay one question so for the Python Barrios module which opens a TSP connection to the director this also works with Python 3 and is already uses Python 3 for the plugin yes as I heard before there is only Python 2 right now but it's already prepared for Python 3 and will also be done soon I guess yeah I guess per distribution because normally we compile it against what's available on the distribution and if the distribution only offers Python 3 we will do it for Python 3 okay other question yes in principle it's yeah it's connected to the director and then you can call the call and put in all the commands you could also enter the B console and so this will be executed and the results will be given to you okay hello how did you know how did you know how did you know how did you know how did you know how did you know how did you know fail over if you want to have a fail over the only thing you need you have redundant database that you do with your database tools and then you can have a second director for this is only important the configuration director ETC Barrios Barrios director and you can copy them over or keep them synchronized and then you can start the other director you never tried we tried it in one project or we did it in one project okay but now not simultaneously so it's just a fail over it is possible that you need to expose those to the internet because maybe you don't have everything in your lab if you are doing remote backups is there a security concern for you of course it's a security concern if you provide services to the internet but yes we are aware that people are doing so you of course should have your TLS encryption configured to do so and probably also what would be a good choice is also to encrypt the data on the client there's also a various option so the support is encrypted and also through the encrypted transport your data is also have been so this should be quite reasonable so all the communication is encrypted and the data the data is encrypted the data is encrypted on the client and can only be restart on the client or if you got the master key also configured somewhere else okay and the second question is the very bare minimum requirements on the client you know to keep it lightweight is having the file demon storage the file demon, only the file demon if you want to keep it as small as possible that's the only requirement you have on the client how resource hungry is that the demon storage on the client like is it very, like do you need a powerful machine, like do you need they think that the director needs to be four gigabytes I think was the best practices I'm not sure about this I know that some people wanting the director and also the storage team so I'm sure that's not so many of course it's not the fastest solution but a lot of people using this this way and also the core components are all written in C, C++ also there you are running on AX APOX from 10 to 15 years old so it's not so so intensive even with big storage like very, very heavy if the data set is growing so if you have to detect the files that have changed since the last backup then this can consume some time and also encrypting the data on the client will also consume time but this is normal so if you have to if you cannot afford this from your CPU time you can configure it to make this like maybe unencrypted but yeah maybe you don't want so okay this is it oh sorry they are planned so the question has been to use some file system management to detect changed files more quickly and this is for ZFS or BetaFS yes and we discussed this and we have also a task defined for it but currently nobody is working on this but yeah it could be hopefully done quite easily but I've checked this with BetaFS and this wasn't this easy because if you want to retrieve the file information that has changed these virtual mount points and then you yeah it wasn't that easy it's easier to get to change blocks but we're not backing up blocks, we're backing up files so also this is not too efficient but yeah with a file demo plugin this can be implemented quite easily okay


Behind it, there's a lot of things for shameful of, but really without the truth side, you're not going to get to their reconciliation. And this is really what a lot of the poems reflect on. They also reflect on the spirit of resistance and resilience and survival. What they really discovered was how much they had in common coming from countries that have been colonized. So, I'm going to introduce the youth, Raven Obey. I'm going to stand up because we're going to have to cruise it for them here. So, Raven Obey. Raven is 18. She studies at Willis College, and she's of Algonquin, Crete, and Bohawk descent. She's also published all of it. Adam Harman King, the baby of the group, he's 15. He goes to South Carlton High School, and is watching his first performance today. He is of mixed Iraqi Arab and First Nations descent, I believe it's Galbey. Is your aunt here? Where's your aunt? Is your aunt here yet? Is your aunt here yet? Okay, but you're such an aunt here yet. Okay. Oh, too bad. His sister's here with Galbey First Nations. Okay, next is our facilitator, Sara Musa. She's Somali Canadian. She's also an accomplished spoken word poet. She's performed at Urban Legends, and really at the print events across the city. And she's really committed to social justice issues. Next is Dustin Pilon Plainer. He's of Ojibwe, Italian, and French Canadian descent. He's a student at Milan Pilata High School, and is 12th year. And his stage name is Disaster. And his spirit name is Sunder Stewart Walker. And last but not least, we have Alan Angel Vesenga. She's Carlton Lee's Canadian, currently studying at Carlton University. And she also is very committed to social justice issues. Thank you. And right now, they will perform any of their group piece, which is called Who Are You? Who am I? They say I am an angel of death, a bird of misery. I will take to get and get to take. For that, I am a trickster. I have soul and fire to ignite the sun, then taking water to quench thirst when the heat became too much. I was even office companion at a time when God was powerful in Greece. I have lived many lives. That of a man, a twig, a child, and a dove. But for now, I am a woman. I am the raven. Who are you? Who am I? I'm Alan King. Well, not really. My name is Alan Lee, the same king. I bet the first in the Canadian line is that I'm a terrorist. Well, no, you're wrong. I'll tell you a story. The reason why I picked Alan King was because it was a common name. Not only that, but it was a person I don't know. My Aboriginal name is Hawkins. The reason why I picked that is because I got a big nose. Who are you? When people look at me, they expect an exotic and complicated name. I am Saara Musa. My name has historical significance. For example, Saara was the name of the wife of Prophet Abraham. And my last name is Musa, which is the name of Prophet Moses. Somali seemed to have trouble grasping the fact that my name is pronounced in the Arabic way. Because usually, when you meet a Somali girl named Saara, the way to pronounce her name is seven. And Musa would be pronounced Musa, but an English that would be written as Mus. I get asked where I'm from like it's a question I've never been asked before. A child birthed into the land of the free with diasporic roots, I couldn't begin to tell you who I was or what made up my ethnic DNA. I'm a Muslim Canadian Somali. It's like the world has a problem with my very existence. As if knowing or rediscovering your identity is shameful. I speak on behalf of myself. I am me, no gimmicks. Who are you? It depends which name you mean. My social, documental name. The name I've been called on my life in terms of my head too. Every request and demand, compliment and criticism has been directed to this name. Dustin McChulkin O'Clan. So it depends which name you mean. The name that gave me a surge of life the first time I heard it. The name I now hear in my dreams by which every spirit I mean calls me. The name that excites and terrifies me, that lifts my spirit, but also confuses the interior of my mind because no one knows how this name describes the exterior of myself, Thunder Spirit Walker. So Dustin Pilon Planner. That sounds normal, right? Coming from a huge Italian family, you'd think my dad would have a more Italian name. Pilon fits my mother's side, however, because she is half French. But in this case, half and half do not make a hole because where does the native fit in? That is why I ventured around in the spirit world for smoking the sacred pipe to find Thunder Spirit Walker. Who am I? Who are you? Who am I? Apparently I'm black. What is that? How do I go about being that? What does it mean? What is its history? So I'm filling out this form and it says, Are you black, African, or African-American? And I wonder, what am I? My mom always told me to speak. Speak who you are and stand fast in it. Be who you be and walk in it with pride. My name is Amoy Anjan Sena. Amoy, the roots and the condo, the land of riches, the land of beauty. That's who we are. This is my every Aboriginal home. For those who feel pain or understand it's not a game. Those people should be ashamed. It's not that you can forget. Those people should have regret. You're not the toy. You're not the pet. They thought you were bad. You have every right to be mad. It's hard for you to be sad. Now, we're the ones that pay. They took our rights and yet we still stay. It's time, it's still the same. Each and every other day. Now, let's gather around and pray. We've been told lies, but truth still hides. My grandmother, she still cries because all her friends is dead. She's had trouble telling me why. It's time to talk. We're somewhat free to walk. Elders are still in shock. It's something that hasn't stopped. I'll show you my heart. It's somewhat hard. They forced me to go to school. Trust me, it wasn't cool. Take it from their homes. They've been tossed and thrown off their feet. If they resisted, they gotta be to the point where they lost their teeth. Let's hope this action doesn't repeat. We were kind. We helped them survive. But you didn't keep your word. We lied. They ripped out women after they screamed and cried. They took their pride. This is a genocide. It's hard to believe both sides. It's hard to fight. This wasn't right. I'm sorry to speak up. I'm sorry to scream and shout. But it's time someone shows his devil. This is the end. I'm sorry, people. I don't blame. These are our experience in school poems. How is it when you try to learn the history of your people when history is white? Admittedly, I only started to care in grade 10 sitting in history class realizing Canadian history does not mean the history of this country's people. Canadian history starts with Johnny McDonald and continues with every other white prime minister, not including at all the aboriginals who cannot be part of their land's history because they were given no rights. Canadian history followed the lives of English and Frenchmen. So pardon my language when I say go win the kidsy. Je n'ai pas de voix. I have no voice. I've tried, mind you, to speak out against my teacher who refused what I wanted to be taught. Both out of second thought, I remain caught into struggle with what the textbook said. I am drowning in a sea of useless knowledge like food that makes you hungrier. I was growing impatient, so don't act surprised when I say I exploded and my grade 11 Aboriginal class taught by my Italian drama teacher. I was told things I was told when I was 10. The basics which don't mean a thing to me anymore because I know more than my teacher. Like not every native follows the medicine wheel. Not every native burns all four sacred medicines and not every tribe has the same creation story. So excuse my rage when I'm forced to Google what I want to know and still don't get one straight answer. It pains me to know I know nothing. Even when I know more than some, I still know nothing. All I want to know is who I am and what my culture is. So forgive my ignorance as being native and not even knowing how. The following is a letter. A lament of all my experiences in school systems. Despite the fact that the history of the people and peoples of African descent is trivialized and marginalized while those of Europeans abstracted and reified as the ideal, I am learning to love myself and I am the black. To your white people, there will come a day when lines will speak. When the society that is so proud you have fought your self having built will be revealed in entirety. There will be no lies that shield you from the brutality of the pain inflicted on the African indigenous race.  Dear white people, I am not where will I ever be white. So stop attaining to aim besides me via your school curriculum of half troops and who's who in great whiteness. This Western capitalist democracy is so far removed from this laboratory as you white as college. When so-called primitive peoples roam about words, exotic things that you speak of with such repulsion then have the nerve to ask me to come and exhibit my culture in front of the class even marvel at its mysteriousness. But if I spoke the words it's at least a moment when it won't be. I told you how this murder in its body incinerated in NASA by Western powers. But ever after these stabilize in the Congo these countries act as security independence.  Dear white people, the Portuguese for centuries prior to Belgian organizations stole human beings from my country. At once the first of the Congo Empire in 1526 rolled to the Portuguese king. Each day the traitors are kidnapping our people, children of this country, sons of our nobles and vassals, even people of our own family, described in the privilege of our land as entirely depopulated. So stop trying to shock me on the greatness of your society. I know all about your democracy I see in the eyes of soul-caused civilized seeping in the blood of my people. Dear white people, don't tokenize me. I will never assimilate. And don't speak to me of play or I could kill us about its republic. I stand on the shoulders of giants. I'm Kamali's, one of the heart of darkness for Portuguese religion enslaved. The Belgian colonizers enslaved us. Exchanged our hands as currencies. Mutilated us and hung out decapitated genitals and heads on which policy is in a formal process. I will not fear you from this truth this is our history. Even if your attempts to forget it I will never. I'm here because you were there. I'm the liest by the fact that slave traders and colonialists estimated the Congolese population by the millions. My family survived enslavement, colonization, genocide, and war. And still we rise in concrete jungles of your inner cities aware yet oblivious to your history books or Africa in the monolithic African as a problem to be solved as you exhaust yourself because of the developmental aid you render as my country remains indebted to those who colonized us before in the words of Thomas and Carter debt is near colonialism in which colonizers transform themselves as a technical assistance as a total assassins. We cannot be paid because we don't have any means to do so. We cannot be paid because we are not responsible for this debt. We cannot be paid but the others owe us. What the greatest wealth can never be paid. That is blood debt. Our blood has slowed. As you gender and African countries have completely barren about your governance. Never mentioning your complicity and our underdevelopment. The human rights you once devolved into were yamas, animals, Negroes, so I will never praise you when your laws are not affirmed by humanity and whether you admit it to or refuse to your complicity not conditionally exist and if ever we are to exist together animosity a true account of history needs to be taught. The white people listen. Negro is not an anthropological term. It's a slave one. The white people colonization not be celebrated but celebrate away because there are a common day in line to seek. When the society that is so proud we put forth our self having built will be revealed in its entirety. There will be no more assasinations from the brutality of the pain you have inflicted on the African-Indigenous race and you also always the great democracy you inherited the main two Greek civilizations will be revealed as a myth. On the problems or the issues I have with with following my native roots but looking white. Am I not native? By the government standard I am not. But what relevancy does this have compared to how I feel but is it enough to feel native? They say don't judge a book by its cover and I guess my cover reads like a simple white boy but if you bother to read my story you would find an intertwined pattern of visions teachings and ceremony experiences that make me feel native. I try to learn all I can to be accepted so imagine my devastation when someone who knows nothing about their culture and abuses drugs and is filled to the brim with disrespect is accepted more than I because they look native. These same people who would sell their purebred roots if possible criticize me for having only one eighth native blood. Though they do not know it is that eighth of my blood that boils, whenever I am enraged, overjoyed, depressed or lost my native side is where I turn because I do not know what it means to be French or what it means to be Italian especially since I have been judged for having these roots as well for the Italian and French helped in the assimilation of the natives so since there is more of these in me I must not be native. One eighth doesn't count especially when you have those treacherous blood in you they say as if it is my fault native teachings are the ones I have been given with an atheist father and a mother and it hurts me to accept what she believes as it pains her to know I believe in spirits that roam the land and I do not believe I should try to live like Jesus because it is already hard enough trying to live like me. When I get profiled as right and describe myself as native it is a constant battle two worlds are warring in me and both sides are losing none of the martyr in me shows my conviction I hang around natives hear their stories of racism and I can't relate I still talk badly of natives and I still can't relate is there really a solution that I can create how do I live with this ongoing debate is there even a way to have a clean slate when I look at the sky I can't believe that this is my fate I'm just going to have to give up at this rate I need now more than ever to break through this gate to be or not to be that is the question that haunts me every day I know not if I am worthy to call myself native not sure if it's really my choice I think when I use my own voice then yes I believe with all my heart I am worthy even if I'm the only one in the world who does it's enough to get to tomorrow when once again I go to battle with myself and again the native blood my native blood will boil with the hunger for victory ok how's the body rich as long well 10 skin high cheekbones all in shake thighs seemingly hiding the answer to whichever secret she was keeping her secret was the same as many scars hidden due to naked eye ones that would never heal yet that she had injured directly mother and grandmother generations beyond had been the ones to suffer at the hands of ignorance despite the treaties the closure of these abominations money handed out nothing would heal the scars left behind things would never be the same she bore the battle wounds her elders bestowed upon her as a memory of her heritage you mustn't forget the children and grandchildren will bear the same markings a simple reminder which cannot be forgotten the battle will never cease as the long as the scars remain good luck this is our final piece it is a poem that was written by two of our performers Angel and Dustin Angel and Dustin my name is Bert Sains even in war zones a battle wrapped I stand armed with my blackness on one hand and my hope in the other the teacher stands with a whiteness all enveloping all around me like air like the poverty that cracked open concrete pavements in outer cities where dreams were swallowed whole you wouldn't know sir you wouldn't know man my pain but it's okay I still hope I still believe in the beauty of blackness even if the teacher stands for arsenals of half truth the rationalization under gaze under a guise of righteousness Lord have mercy it's enveloping all around me like air I sit waiting to exhale waiting to be free but I know why the cage learned Sains I know the founding fathers will lie I know principle Columbus didn't discover the Americas and I know black is beautiful and I know you can never have justice on stolen land so why still do we battle in our pill war not for the hope we carry that one day the cages will be blown apart releasing our spirits giving us the freedom we need to succeed victory comes not with the other side defeated but only when both sides come out for better bearing more knowledge than ever before we fight against history denying the founding fathers their right of way because we know no country was founded it was taken over and some say we can never have justice on stolen land but I believe as long as pride runs through the veins of those who cling to their culture that the other cities can be rebuilt and soon they will tower over the buildings meant to keep us in prison we cannot contain our souls so instead contain your criticism so that all may be equal in the eyes of all someday we'll both put our weapons down your white gun and my blood slingshot and we'll display our human beings studying learning being together but not until you put down your lives not until you tell the truth not until you give back what you took until then this will always be a war zone and I won't put away my slingshot until you take the bullets out of your gun and stop shooting ideologies of white supremacy disguised as truth set me maybe you don't mean to maybe you do but you can't separate intent from effects it doesn't matter much now because even if I'm never experienced and as often as I ought to I still write poems to my black teachers and never wore faces in your schools as they should be my pet place of moomas, my Tom and Starr covers my sadistic shepherds healing you in his inquirming tours I still dance in the heartbeat of my ancestors when seven-year-old revolutionaries in the Congo lay down their last part of liberation I know the Congo cries I cry my mother's cry, my father's cry my wife's cry but never in front of me took always alone in rooms rooms within rooms where caged birds sing even in war zones sometimes an art of my imagination is cringing beneath my feet to do sounds of my ancestors pro-feed eyes dancing and laughing again you do not break them you cannot break me I know why the caged birds sings the caged birds sings sometimes wild when no one watches I remember hearing stories of how my great-grandmother survived residential school and now I hear stories of how the Congo survives and I think to myself with the combined efforts of slingshots and arrows we'll work together to take back the sky and the land so watch out for the birds and the horses because we cannot stop fighting the warrior pride will not allow it but if somehow we can come to an agreement I can see purpose overcoming pride we may lay down our weapons and fire truth and love instead of leaded stone one day my daughters and sons will no longer need to carry around slingshots and you won't shoot them down with your guns will display us human beings studying, learning, being together but not until you put down your lives not until you tell the truth until then this will always be a war zone when the time comes for us to truly be together we'll leave you ready there will always be those hot-headed there will always be those whose hot-headed ideas build walls to separate us what will you do when a quality requires you to turn against your own can we put truth before brotherhood when the time comes our does is what we've built so hard to create tumble like the culture destroyed by the same hands that cling to hell of them if we can all agree to put the needs of those who look different other the ones those who look the same as you that will rise as humankind to levels we never dreamed could be reached it is prophesied that one day the land will lie with the lion and now is the time to decide whether that is the fairy tale or to the ship set sail for the coastline of a new tomorrow in which all cultures live together and we use our weapons for firewood and we dance around the flame of justice raising the universal flag of equality and respect we believe our daughters and sons will have the strength to invent our weakness and set it aside for the furtherment of tomorrow and the betterment of humankind
