So coming back to the original question posed by showman is that why we talk about two different sigma. So actually when we talk about that I am taking a mirrored image and looking into that particular reflection that we got and try to rotate it so that to see that whether it is super imposible or not over there when you are taking the mirrored image the mirrored plane is actually outside of the molecule okay I didn't put that mirrored plane inside the molecule. So that is why it doesn't really matter where I am putting the mirrored plane outside the molecule because over here my goal is not to find whether the molecule itself it is reflecting because when you talk about a reflection plane the reflection plane generally stays inside a molecule and that is not the case over here. Over here what we are doing we are trying to get the mirrored image as simple as that. So doesn't really matter where I am putting the mirrored plane so anywhere you are trying to take the mirrored image that will be the same. However when you are talking about an original improper axis of rotation SN over there what we say that we have to have a CN axis of rotation that means there would be an axis of rotation which belongs to the molecule and there will be a Sigma H plane that has to be inside the molecule. I cannot put that Sigma plane outside the molecule because the symmetry elements has to belong inside the molecule so that is the big difference we are talking about. So during the time when I am trying to find out whether I am having a mirrored image which is super imposible or not I am taking the mirrored image outside. So that means that is actually going to have a Sigma plane. And now that mirrored image will obviously going to match the same result if I take a Sigma plane in any of the possible plane present inside the molecule it has to be. So that is why now the change I can make it where I am putting the CN axis I have to put it just perpendicular to the Sigma plane. And only then I can say I have a perfectly ordered SN axis. So the big difference again when we are talking about a Sigma plane Sigma A Sigma B Sigma D with respect to symmetry elements that has to be present inside the molecule that has to go through the molecule. Whenever I am talking about a mirrored image of a molecule I am taking the mirrored plane outside the molecule that is the big difference. Does it answer your question so many? Yes sir. Sir are you writing something? No I am not. Okay so any more question? Sir I have a question. Yes sir. Sir actually the molecule content molecule is of D3's point group I know that. But I feel that the molecule means the 4 oxygen atom is there that containing a plane. If we take that is a molecular plane and then I think that Sigma H is present. I mean I feel that it is Sigma it is the Sigma H or not means from. Sir you get my question. Yeah I think you are talking about this metal bound with 3 bidented ligand you are talking about. Yes sir it is you have shown in that like that that one oxygenate upward to the plane and one is below to the plane. But generally when we are talking about when we put in a means when we try to draw the molecule in a plane we just show that that 4 oxygen atom that is in a simple plane means it is a plane only. So in that way if we found that that could be the Sigma H because C3 is perpendicular and it will reflect the upper oxygen to the lower oxygen. So is it possible that that plane is the Sigma H. So if I understood your question you want to say like this particular 4 oxygen containing plane is it a Sigma H or not that is your question. Yeah I feel that that is the molecular plane and Sigma H also because that is the perpendicular to the C3 axis also. Okay so let's take a route on that and let's discuss this molecule. So now first of all first find it out whether it is a Sigma plane or not. So let's do a Sigma orientation over there. So first all the oxygen as it is we will draw first. So these two oxygen say I am putting O1 O1 O2 O2 O3 O3 for my understanding. So O1 O1 will remain in the same plane fine. Then this O2 will remain in the same this O3 is remaining in the same plane. What happens to this O2 if I am doing a Sigma orientation or Sigma operation to this plane. This O2 will go down. So now you can see O2 O2 and O3 O3 are to connect. The oxygens are remaining but the connectivity is different. And that is why there is no Sigma plane. Okay so thank you. Any more question? Okay so you might have a lot of questions regarding the quiz so don't worry about that. We will have that at the end of the class and this is a little bit different quiz than probably you have faced so far.  Not much on that to be honest and it is obviously not going to depend on how much you can remember. So there will be a few questions where it will ask you a question a little bit philosophical in nature. And that will require whatever we have gone through that class on that particular portion how much we can use that particular knowledge to probe those answers. So don't worry about that too much it is more of for my understanding like if you guys are following the points I want to deliver or not. And it has a minimal effect on your grades because I generally over there will be grading with respect to like whether you're following the correct thought process or not and not really on that what is your actual answer. Okay so it is not a binary kind of mathematical question that if you have that answer you get full marks if you don't have the answer you'll get zero nothing like that. So the questions will be a little bit as I said philosophical in nature. So you will put through your answers and then you will go through that. But anyways we'll come into that little bit later. So we'll proceed forward. And before that over there I want to write no sigmage plant present over there. And the other thing over here is that this plane over here what you have drawn. And actually it is better to see if you actually draw the octahedral side probably better. So this is I'm actually trying to draw the octahedral field how it looks like. So it is called octahedral because there are eight head or faces. So C3 actually passes through here. And your sigmage plane that you are trying to tell or go that is over here. So they're not really perpendicular to each other. Okay and then that what Somen was asking what happens to the C2. Now C2 is over here it may look like it is actually not in the perpendicular plane. That is because it is a line not a plane. So now if I look into this particular angle this angle is actually 90 degree. Okay because it is actually a line like this and on the top of that I am putting my C2 over here. If I look through the C2 over here. So now you can see the C2 is sitting perpendicular to that. Right because there are two lines because I'm looking in such a way it may looks like it is not. But if you look through the C2 you can find the C3 is line like this. So this is the C3 this is the C2. So they are actually perpendicular. Okay so Somen give it another try. Don't always try to look into a molecule try to visualize in your head that is the best way you can see it. So generally if you try to find out whether they're perpendicular or not the best way to do that is put your visionary angle or visionary direction through one of the axis or through one of the plane. That is the best way to find out whether they are perpendicular or not. Okay so give it a try later and if you still have issues please let me know. Okay so thank you so we'll go to the next portion. So so far what we have done in this particular class that we have gone through the molecular interaction. So the molecular recognition that we have found out that that is actually has a big role to play. And we have discussed that molecular recognition system has a big role to play with the chirality. And that is why we are actually interested in chirality. And then we figure it out biology is actually a system which actually has a lot of chiral centers. Okay and those chiral centers are coming from the proteins coming from the carbohydrates and even from the nucleic acids RNAs and DNAs all those things. And again this chiral center doesn't always mean it has to it have to have only a chirality present instead of the molecular level. That means that molecule with a carbon with four different groups not always. It can have a secondary structure made out of like a polymer of a even a acryl molecule. But the secondary structure is such oriented that this molecule can be chiral in nature. Okay we'll come into that little later like alpha helical beta sheet all the structures of the protein and how they are chiral even though the original molecules which are actually making it may not be chiral. For example glycine. Glycine is not a chiral molecule right. We actually have gone through the structures and if you make it a polyglycine and this polyglycine can make a alpha helical structure and this alpha helical structure can be chiral whereas this glycine itself is a chiral. So don't always look into what is the I would say that the backbone or even say like the primary units that is actually forming the polymers or the polymeric or the overall structure of a system instead in the terms of protein carbohydrate or nucleic acids. It's not always to be the binders the forming units has to be chiral. The overall unit can be chiral. For an example, nucleic acid the nucleic acid the simple system the nucleotides they're not chiral. But when they make the RNA and DNA from the helical structure they becomes chiral. Okay so that we have learned and then the other thing we learned we learned what is an laminate acid and we now learn how to draw laminate acid and we actually learned all that 20 naturally occurring amino acids and how they're actually drawn what is their one letter and three letter code and how they're actually defined over here. So that we have learned now the question comes in this particular fashion over here is that does this laminate acid and daminate acid really actually matters and what is the effect of the presence of a laminate acid and daminate acid mixture in the system. So that we will discuss in details today. So the first question is if I look into biology in biology you'll find laminate acids at the predominant ones. So if you find any amino acid in biology or it is coming from a biological origin you'll find it is l in nature and the l terms define that it is actually having a particular spatial orientation of the groups of the carboxylic acid group of the R group of the NH2 group and they form in such a way that my amino acid structure. So when you draw these amino acids in such a way the hydrogen goes at the back carboxylic acid R group which is also known as the side chain of an amino acid and that is the most important part because the rest of them are actually very similar for all the amino acids and they are actually makes generally the backbone of the system forming an amide bonds. So this is forming such a way that if you connect the carboxylic acid group R group and NH2 group they form a left hand rotation or anticlockwise rotation so this is known as the laminate acid. Whereas if you take the opposite one it puts the hydrogen over there now you put R group over here NH2 group over here now you can see CORN goes to this side and this is known as the daminate acid. So if you look into biology most of them falls in this part. So their special orientation is in such a way that the carboxylic acid group R group and NH2 group form this left hand orientation which we already discussed as the CORN rule. CO stands for the carboxylic acid R is the side chain N defines the amide groups. Now the question is why it is important. So for that I will give you some examples and from those examples we try to understand how important the presence of the daminate acid or the laminate acid R for the functions of the biological entities. So the first example I will be giving is the following. We will talk about the bacterial cell wall. So whatever the biology we all studied from our school we know their important feature in the bacteria which is known as the cell wall which stays on the outermost part of the bacteria and it actually helps it to survive all the toxic behavior any other things coming towards this way and helps us to survive. So cell wall is actually the very important protective layer for the bacteria. Now we learn it all together all these things in schools but now as we are chemist and most of our in the PhD and the master's level or higher standard of the bachelor's level. Now we have a better idea like what these particular cell walls are made of. So if we look into carefully we found the cell walls are made out of this very important factor called peptidoglycan. So if we divide it up one side is peptide one side is glycan. So peptide is nothing but peptides that means protein. It is again forming between amide bonds or peptide bonds between different amino acids. So that is its name and the glycan defines carbohydrate molecule. We have discussed that a little bit earlier that what we have we actually have a protein entity a protein structure and on the top of that we actually have a carbohydrate motive something like that. So these are the carbohydrates and these are the proteins and this full section will be called the peptidoglycan and these are actually the building blocks of the bacterial cell wall. Now the bacterias can have different effects on human life. Some of them are good which are actually living in harmony with us and some of them are bad which actually tried to get our metabolic systems out of our way and use that for their own purpose. So those are actually not bad. And for that what do we use? If I want to kill a bacterium we use in common term antibacterial reagents and how this antibacterial reagents in typically it works. Antibacterial reagents are nothing but chemicals because now as we are in a chemistry class we try to look everything under the scanner of a chemist. So when we say a bacterial reagent if we add the bacteria dies that is what life science or biology says. And as a chemist we try to understand wait a minute it dies it's fine but how it is actually working what is the reaction is happening. So what we found this antibacterial reagents are nothing but something called protease or some chemicals that actually activate protease. What is protease? Protease is nothing but an enzyme that can cleave peptide bonds and why it is critical? Because once you start cleaving the peptide bonds you are going to create some fusions inside the wall. So you are going to breach the wall around the bacteria and once you are starting breaching the wall the protective layer around the bacteria will be gone. And once this protective layer is gone now it is vulnerable. Now it is going to get attacked by all the different conditions. For an example in our gastric juice it is a very strong acidic region is present over there which goes to even pH 2 to 3. If you put any protein over there that is going to be just chewed up. How about the bacteria will survive over there? How? Because this peptide or glycans are actually putting a protective layer and fighting with it and make it survive. But the proteins present inside the bacteria they might be or even the nucleic acids present in the bacteria they are vulnerable to this strong acidic condition. But the bacterial cell wall is actually protecting but once this protease come into the picture and start cleaving that proteins present in the cell wall that is going to put a fissure. And through that the acid or the protons can get into the system and kill the bacterial proteins that are important for their metabolism or the nucleic acid that are important for their survival. So that is how a protease work and that is how the antibacterial reagent generally works. Now it is the survival of the fetus. So generally this protease when they are working they actually work in such a way that they generally live a particular specific peptide bond. And depending on which particular peptide bond they like they actually have different names. I am not going into the details of that. So this protease for example one kind of protease is such that it likes if there is a arginine I will detect it. How they will detect it? If you remember the arginine has a huge side chain which contains a guanidine group. So they probably detect the guanidium ion and sits over there and then whatever the peptide bond present just next to it it just clips it. So that is how the protease actually detects the side chain what is their functionality and live one of the peptide bonds and that is how the protease work. Now as we are just saying the bacteria are not going to live this war as it is. They are saying okay you have protease I cannot defend myself very well against it because that is very strong reagent and a very strong actually acid based reagent which actually can clip my amide bond. The amide bond cleavage is nothing but an acid based reaction. So how I can survive it that is the thought process of the bacteria. So bacteria says like okay let us see how the protease is actually detecting the peptide bond and as I just said the protease for example this is my side chain of this peptide ligand. So there is a huge peptide ligand and I draw it such over but in reality if I look closely what we will find that is nothing but amide bonds next to each other. Right CH and there is this R group and then there is this NH group there is this carboxylic acid group and so on and so forth. And say this R group is very critical for understanding or recognizing this protease when it is coming through say this is the protease it is coming through. So it is understanding this particular R group detecting it again molecular recombination and then it clips this particular peptide bond and that is how this protease works. So the bacteria thought like okay I cannot stop it because I have to make my bacterial wall in such a way that it has to have protein I cannot get it without protein. But how can I change it without a huge amount of different things inclusion of different things. So for example you can totally change your the sequence of the peptides that is possible but for that just imagine how much change you have to do into your gene you have to totally put a totally new genetic material. You will end up putting up a new species yeah that is a possibility that you will put up a new species to survive. But that kind of evolution doesn't happen at a day it requires millions years of evolution to reach there. So how the evolution starts evolution particularly typically starts with one point mutation so it's just changed one amino acid at a time or something like that. So biology can try that but the issue is that when they are trying it the problem is that they change one amino acid but the protease can still work and bind a different portion of this system and leave it. So what they want leave everything as it is so that the protease still try to find this particular R group but I want to change such subtle change that even in the presence of this R group the protease will not be able to detect it. So how it actually done so what the bacterias does keep the R group same keep it an arginine group but instead of L arginine they change the whole system L to D amino acids. So now when you change that system to L to D amino acid now you know enantiomers their actual properties are not that different. And over here you can argue there are different chiral centers are also present so they are basically diastereomers not enantiomers but for the sake of our discussion making it simple. We said if I change from one L to D amino acid the overall property overall structure is not going to change a huge amount but the subtle change the orientation of the R group will be slightly different. And such a small difference play a huge role because this protease when it comes and try to detect it it try to bind it it has a particular binding pocket. The binding pocket already have a particular orientation present over there that can envelope that R group. However as I go from L to D amino acid it changes subtle way it moves in so much little way but it totally breaks down the interaction between the protease binding site and this R group when it is near to this peptide backbone. Because you have to stay near to the peptide backbone so that it can act it is not only binding to that R group but also staying close to this amide bonds because that you have to break. Now when I change this R group from L to D the inter the inter inter nuclear distance between the R and carbonyl group changes and that actually shifts the whole scenario. Now the protease cannot bind the R and cleave the carbonyl group the amide bond together because that is not the binding pocket of the protease. So that is way you can still go under the radar without activating the protease and that is what some of the bacteria actually does. They actually very smartly change only a few of the points L to D amino acid and they understand which of the amino acids are close to my binding pocket of my protease and only those amino acids they actually change. And once they change it what happens they actually can goes around the system without getting detected by the protease because protease has to first detected through molecular recognition and only then can bind and cleave it. And the bacteria are smart enough to change from L to D without changing the overall structure a lot and get undetected and that is how it actually works. And what it is found that it is reality that some of the D amino acid inclusion actually increases what is called the virulence or I would generally particularly say the stability of the cell wall, bacterial cell wall even in the presence of the protease. So that is how a D amino acid, L amino acid mixture is actually very important. And it is find out that when the bacteria are trying to do that they generally try to put only those amino acids which are generally a part of this molecular recognition program. So it can disrupt the molecular recognition pattern and get undetected. So at the end of the day I will share you some reading materials that you can read more in details and try to get some more ideas, more information about this system. So over here I am giving you the overview how it actually works. Now there are multiple examples of it. I am not going to go through each and every example but I am just going to give you how it is actually work over there. So that is one of the system how it actually works.


God can use natural means to bring supernatural results in a story of Peter It is pretty obvious and it's pretty clear that God's supernaturally intervened into his situation But we see there's other Prison breaks in the Bible where God used natural means to bring people out for example Joseph Joseph was in the in the prison and Joseph did not have a 10 year or a 15 year sentence We actually assumed that Joseph was supposed to be in prison for the rest of his life It was most likely a life sentence and Supernaturally God gets him out But the way the Lord got him out is by actually using natural means in the prison He found a man whom he helped with the dream and this man Told the Pharaoh at the point when Pharaoh had a dream and couldn't find a translation and next thing that happens It led Joseph out of the prison into the palace. God used natural means to bring supernatural results We see also in the life of Paul when Paul was in prison for preaching the gospel The God caused an earthquake to happen and through the earthquake Apostle Paul was able to be released from the prison But in this story, we see supernatural invasion of God's angel into the prison of Peter to get him out Before we mentioned the supernatural ways of God we have to not miss The God can use natural means to bring supernatural results in our lives There are people who will die refusing medicine because they say I want God to heal me only Supernaturally not knowing that the Lord can use medicine to also touch your life There are people who will reject a certain thing that the Lord will do because they will say well, I want only this way Elijah did not say to God. I will not receive food from Ravens. I want food like Israel in the wilderness I want men not from heaven. I don't want unclean unpopular Unpleasant bad birds bring me food if Elijah would have been picky about which way God is gonna use to bring Blessing into his life Elijah would have starved to death Naaman did exactly same thing. He came for healing He came for supernatural result and the prophet says go and baptize yourself seven times in the river and he says what I Don't like this. I want this but I am very picky about this You have to be so focused on your miracle that you're not picky about the method. God is gonna used to bring it into your life Because somebody say amen It's like the story of one person who was drowning in the sea and they drowned and they came to heaven Fussing and screaming and yelling God. Why didn't you rescue me? I cry out to you and God says I send the first boat You declined them. I Send the second boat you send no to them I send the third boat and you said to them that you're waiting on me All of these three boats were actually me trying to rescue you Many times in your life and in my life the Lord will use natural means to bring a supernatural breakthrough in our life And we have to be as Christians not be so picky About the methods God's gonna use but be so preoccupied with the miracle that God wants to bring into our life and not miss that for the glory of God


Time here for more systems. We're going to talk about Synology. Now, Synology is something we've been deploying for a while. I really like their distation manager software. Their hardware is actually proven to be very reliable as well. So what we're going to do is to talk about some of the business use cases where we deploy these for our clients, some of the problems that they solve, and kind of the ecosystem of Synology including, you know, which options are available for them, and some of the great tools that we really like that Synology includes with their distation manager. So before we jump into all that, if you could hit that like button and let's first, if you'd like to learn more about me and my company head over to laurancesystems.com.

And finally our forums, forums.laurancesystems.com is where you can have a more in-depth discussion about this video and other tech topics you've seen on this channel. Now back to our content. And we're going to start right here with the Synology power brick. There's probably someone left a comment before getting this far in the video in all caps or even a link to Gamer's Nexus, who in 2018 did do a video that discussed the fact that their Synology had failed. And a NAS failing based on a power supply problem is a real concern. I completely would agree. And since then, Synology on all the ones we have deployed has always had external power bricks, with the exception of some of the rack-mounted ones. But like these smaller ones come with a power brick, we've had no problems with these. I believe there may have been an issue because I've seen people commenting about this from several years ago. And Synology listened to the audience and people on there complaining about the problem. They were aware of it. They saw the problem. And I am unaware of any current issues to Synology regarding them. And we've been deploying Synology for quite a while. Actually started probably around 2018. We started putting a lot more of these in clients 2019, a lot of them, and even more in 2020 here. And we've had none of these power brick failures. But failed concern. I'm at least going to address that. I know that was a problem in the past and the problem going forward doesn't seem to be an issue. And I recently reviewed this Synology with the HA option, which has removable power supplies. And that one seems quite reliable as well. Second, and this is a really valid concern as well. And I was confused on this until I did a little further reading to make sure I understood how what was implemented. And this is the RAID versus ButterFS. Now, ButterFS is not as popular as some of the other file systems, but does have a lot of great features of a modern, you know, journaling file system. So we can do RAID. We can do snapshots. And it's great, except people will tell you it's not stable. And they're right and wrong, depending on the context of the question. So in the context of if you were letting ButterFS handle the disk RAID, yes, there are some stability issues, which is exactly the discussion they have here. And I'll leave a link to this is right from Synology. That's why Synology said, no, we don't let ButterFS handle the disk. They're handling it inside. There's Linux at the core of these Synologies. They're handling it separately and ButterFS on top. So ButterFS, you get the journaling and the snapshotting benefits without having to deal with the problems you may have if it handled the RAID. So they have a separate RAID manager to handle the disk and then ButterFS on top. So failed concerns. And hopefully that addresses them and gives you an understanding of Synology and where they may have been before and where they are right now. That's always an important piece of context on there. All right, now let's go and start picking and selecting the NAS itself. Something I like that Synology's done is made the NAS selector. And you can just start and say, I'm a home user or small office or I'm a business or enterprise. We'll start with business or enterprise. And we can just start checking all the things only once we pick three at a time. So data backup storage for virtualization, file server. Yeah, those are good ones. Or let's say collaboration. That's another option because the disk station manager software has some good collaboration tools on here. So we'll go with these ones right here. We'll go file server, data backup, storage. All right, next. How many people? More than 200. Yeah, probably only 20 to 100. We're talking a lot of small businesses here. How many concurrent users? Fewer than that concurrently. So let's go down IOPS, regular. You can kind of see they'll drill this really down. Let's start over and go something simple because we don't go through every option on here. I'll leave that for you to choose. But this is actually a nice thing. They make this part a lot easier to say, hey, maybe I'm just a home user and I want a productivity or multimedia hub. Those are important like you want to run Plex. And you can also do the same thing. Do you need image recognition and to automatically organize your photos? That seems like a cool feature. There's only a couple of people at my house, one to 10 or one to five next. And now we have a couple options presented to us. So they give you a couple of different ways that you can go through there and pick out what you want. If you have an unlimited budget, just pick the highest end one that will do everything. But if you don't, well, they have some things that you don't have to overbuy. But it is important to try to buy up to what you're looking for in terms of power and performance. Now, this is kind of scroll through the product line here. As you can see, they have quite a few different machines. The two that we're looking at it kind of on each end of the scale is this is the DS220 Plus, which I believe is the replacement for the one next to me right here, which is the 218 Plus. This is a little bit older of a model, but works perfectly great for all the testing that we're going to be doing with it. And the other one we have in here, which is in the other room because it's noisy is the SA3200D. And the nice thing about this is both of these, and we'll pull them up over right here, are running the Synology Distation Manager software. So it's one and the same in terms of looks. Well, we've actually changed the theme a little bit on this one. So it looks slightly different. So our little two shuttle bay as we named it right here is running the same software and has the same package manager, has the same package manager on both of these. I really like this concept because it's nice as the SA3200 is, you still need a backup just because it's got RAID, just because it has redundant controllers doesn't mean something terrible couldn't happen. So what we did here, and this is we're going to start covering some of the software shortly is set up this as a destination with a pair of drives in there. So you can actually put a couple large mirrored hard drives, so certainly not for performance, but you got to put the data somewhere. And you can then buy and we'll cover how the setup works on that. A really inexpensive backup Synology to your much more expensive higher end Synology and replicate all the data between them. So you have a nice solid backup that you can go back to and restore. It may not be the fastest, but important part is that, you know, if there's a major failure, you have a way to back it up and we'll jump into that here in a second. But once you've gone through all the options on Synology and pick the right one for you based on the software and features, whether you have a very specific need like this active backup for business, the butter FS file. So I think all of them have that on their snapshot replication or the high availability options they have where we can narrow it down further like the virtual machine manager, you can kind of see they really have a lot to fit with the small business, the home user, and even some of the larger markets that, you know, may need file service storage for virtual machines. Now that one other thing of note they do have is expansion modules for these. So some of these you can buy some of the rack mounted ones can be bought as a head end unit and then you can then expand out a couple more units on it. And I covered that when I talked about the high availability one that we reviewed and I'll leave a link to that video as well. So you have that other option of not just getting the number of drives that will fit in that chassis, but buying a couple more chassis to expand it out further and have one act as a head unit. So they give you a lot of variety of options in hardware. And like I said, we've been really happy overall with the reliability of it. Now let's get to the good part, the software and what makes Synology so great of a system to deploy, especially for small businesses. We'll go ahead and start right here. Easy to use and built for everyone. This station manager or DSM for short is an intuitive web based operating system for every Synology NAS designed to help you manage with your digital assets across home and office. And it's really a slick system I will admit. Now the first question that comes up a lot because I talk about a lot of open source things, although it is built on Linux, Synology to station manager itself. Yes, I know there's projects to make this happen, but it is not designed just for you to load and roll it and build it on your own hardware. So it is specifically designed as a package system for the Synologies. And it does have a lot of open source things included and a lot of other things that Synology includes, such as your active backup for business G Suite active backup for Office 365 and a lot of other great features in here. We're going to cover the more common ones, but I'll leave a link here to see the entire list of software on here. And it's pretty exhaustive. They do a great job of having a lot of options and a lot of diversity that they offer with their systems. And let's look at the distation manager itself. Now how this gets loaded on Synology, you pop a couple of drives in, you open up your, you know, Synology IP address after you get it on your network, and it loads this automatically. It loads up the Synology distation manager and let's close all these crazy windows I have open and essentially start from the beginning. So when you log into this the first time you're presented with, you have the control panel, you have the little resource monitor over here. And I kind of like, even though this is all a web interface, the operating system like feel that you get of this, like the whole user interface experience you have is really nice with Synology distation. Now this is on the SA3200 and this one over here is the smaller, the one sitting next to me, the 218 plus. And they still are reasonably fast to open up functions, change things around, go in here and change like, well, let's say the network setting privileges for the portals, et cetera, et cetera. It's all relatively easy to go through and just check boxes. And I find it pretty intuitive for the control panel, but there is a lot here. So there's a learning curve, but don't worry, you can click the question mark, and they have the entire DSM help built in. So it'll walk you through each thing, connectivity of file sharing, setting up or creating a shared folder. And it's not taking you to an external website, they just included all of this built right in, even how to do the ACLs and permissions, et cetera. And this is the nice thing about Synology Submarine Listation is they really try to make it so you don't have to be super technical to get it going. So reasonably easy to use is how I would say this is as long as you know what you're looking for and what you want. Now the package manager, of course, is where all the fun is at. So once you've got the general settings done and how you want things to be set up and configured, and you can back it up here and back up the config settings, et cetera, and do the updates. The updates are really easy to do. You're just going to go ahead and choose an update time. As a matter of fact, while we're waiting, we'll go over to this one. And I want to show you how the updates work. I left these not installed on this 218. We'll just hit update all. That's really it. It's going to go ahead and update these. So you can even choose auto update. So we'll just say update automatically, hit OK. It's already kicked off on these ones here. And we'll let that run in the background and do its thing. So as these packages get new versions, you can tell them to auto update or you can update them yourselves. And it really is as easy as clicking update. What about installing packages? Well, they've done a good job of making that easy as well. So we'll let this right here, which the 218 is not really that fast. So it is pulling a little bit more CPU, as you can see in the resource monitor. But yep, that said, it's done. And let's do something like install the active backup on here. So we'll go ahead and set the active backup for business up. It'll go ahead and download, go through the complete install, and it will prompt you to essentially activate it in a second. So it's going to go through the install process. And we click open. We click activate. Agree to some terms and conditions. Log in with your Synology account. Package activated. And away you go, you have active backup for business all set up and ready to go. Now active backup for business is one of the first ones I'm going to talk about. It's a great solution for even if you're running this at home, you have a few PCs you want to backup. You want to back up the files on them and nobody backs up. So you should always set something that does automatic backups where you load a utility under computer and back it up for them because users will just keep using and go, I'll back that up later. I'll press that backup button later. This is something I've dove into on my channel here already. I'll leave a link to this. The active backup for business is a fully automated. You can set it up and have it automatically continuously on a schedule, at least back up the entire contents of a PC of a server of another virtual machine and store them all here on Synology. You can even create user interactive portals so the user without interacting with you can go to the Synology and restore their files and restore points in time to those systems. And of course, now you're protecting those systems from catastrophic failure. So if there were a large failure of that particular machine, you could go back and I've covered this in the video and completely bare metal restore from the backups that this creates both incremental and full backups. So the active backup for business, definitely a great feature on the Synology. We're going to switch over to this Synology and show some of the other cool things that we have on here that are, you know, things we definitely like to deploy depending on the use case for a lot of our small businesses. If you've done any work in business, compliance is a word you probably have heard quite a bit and we have the active backup for G Suite and we're going to go over here and we have the active backup for Office 365. Now the active backup for Office 365, I've actually got configured in here. So we're going to go ahead and launch the portal for it and show you what it looks like. But it's a similar one for the active backup for G Suite. I just don't have that one configured right now. And I don't have a video to link to. I'm working on a demo video of this. Now we'll go here and choose the role. We'll choose Hans, the demo user we have set up and we can look at the Office 365 file system backups that it does. Now just because you put everything in the cloud doesn't necessarily mean it's backed up. What if someone got a hold of your account and then started purging things? Or you have a rogue user who may be purged emails and inadvertently did this, whether it was malicious or not. If those emails are gone, the cloud necessarily doesn't necessarily a backup. And this is where Synology has a solution for that compliance, where we have to be compliant and make sure we have archived copies of your emails. You can do that on the Synology system. So you connect it to an account, individual email accounts, groups of email accounts, and you set it on a schedule to back up those email accounts. Like I said, I've got a demo coming on this, but I'll give you a preview here of how that looks. So right here is the inbox as it looks today. And we're going to just jump around here. And we can slide this over, choose a different date. And we've jumped right here to 820. And we see there's actually quite a few emails in here that aren't in there when we switch it back to today. So what if we want to restore those emails? Well, you can. You can just go here, check the ones. We can export them. We can restore the entire folder, just click restore. And it'll push those back out to the account. We have a local copy here. So while many people are talking about putting everything in the cloud, you can actually now, since it's not on site, you can use on site as a backup to the cloud. So you have more than one copy. And Synology makes that pretty easy to do. And especially for people who have a lot of email and a lot of data to back up, it can be expensive by buying another cloud service to back up your main cloud service when you can just get a Synology and back it up there. And then you can back up to Synology sometimes for the price of what it would cost you to have a second cloud service to back up. It also, and I'll mention this, has the ability just to export them right from here, both the files and the emails. And because I have .eml associated with just opening up as a text file, it does allow me to open it up here. But of course, I could import this into some other utility, but you can get those out. And the same thing with doing the calendar, contact and drive backups, I can go in here, expand this out and get a specific file I may want out of here. So if I wanted to download this right here, we'll go ahead and export it. And I was going to download right to my local system here is I need that file. And even if they've deleted it in there, once again, I have timelines to see what their file system look like at any given moment. So that's a really cool application that they have in there. Now in terms of file synchronization, we'll close this one here. We have, get too many windows open, the Synology Drive Admin Council for the Synology Drive Sync. Now I like how they call the drive because we have one drive, we have Google Drive and now we have Synology Drive. What they're doing is creating a system that can compete with them where you load a file synchronization utility on your Windows computer and then synchronize it with your Synology Drive. So you have files in here that are synced between the different PCs and the Synology being the central sync point for those files. So that is another kind of neat utility on there. We don't use it that often, but it is a nice option for people who want file synchronization utilities to be able on there. Now the hyper backup is cool. But of course, if you're storing everything on here, we would want to replicate this to yet another Synology, right? Well, they built that in there as well. So let's look at the hyper backup.  And we can say back up now. So let's back up any changes that may be on this system. And what we're doing is we're backing up to this 918. So the 3200 is in the other room that we're logged into and showing you on the screen. And then this is the 218. That's the destination for it. And this is a really nice compatibility feature of Synology, even though we have the nice high end, no expensive model Synology, we want to back up everything on there. We can create a backup job. And we'll go ahead and do this to add a backup. What do we want to back it up to a remote NAS device next, you enter the IP address, and I entered the IP address of this 218 sitting next to me, you put the username and password in. And that's it. It starts running the backups. There's really not much else to it. So actually, I'll walk you through it real quick. So we'll go here, data, Synology, next. And if you hit the little poll down, it searches the local network and can find it for you. Username is LTS, password. We're going to just copy it out of Bitwarden over here. So you go here, copy password, paste. It can look up YouTube demo, next. Pick what you want to back up. Just check the box, do everything. Next. Yep. Back up all those applications, send that data over there. Back this NAS up to there we go. Apply, just let it do the backup. You can choose rotation settings on there. They've made it really, really easy to take two Synologies, have one as a destination, and one as a source. We'll say, yes, we're going to let it back up and let it do this in the background. So we can have this job at running at one schedule, this job running in our schedule. And of course, you can do this in reverse. You can take the two Synologies and maybe they're both, you know, you have a client with more than one remote site and they want their remote sites to be their offsite backup. Synology has got you covered on that. They'll let you pick those as destinations back and forth. So another feature I really like is this hyper backup. And if you didn't notice, if I scroll down a little further, it does have the ability to choose Amazon Drive, Dropbox, HDrive, JD, Cloud, Microsoft Azure, IBM SoftLayer, Google Drive, and S3 Storage, which is different than Amazon because it can do S3 specific URLs. And I've never used this, but apparently it has S3 China in there. That's kind of interesting. So if you'd like to send your data to China, or maybe for compliance reasons, you can't let your data leave China. That is an option that they have in here, which is pretty slick. All right, onto a couple more features. Now I didn't dwell on this, but maybe I should at least bring it up. Yes, this is a full-blown NAS file server. So this will do Windows share emulation. So you can create folders and shares and everything else. That is completely a native, not application, but a native system that is built into this. It also, and I covered this in my other video when I reviewed the SA3200. Yes, it does both iSCSI, it does NFS shares. So all the other general NAS expected behaviors, I don't want to leave you assuming they're in there, but I will assure you, yes, they are in there so you can set all those up, including managing users, managing permissions, and creating user sets. Also, and this is another question that's come up quite a bit, is can I replace Active Directory? And actually you can. They have the directory server built in. So let's say you have a need for Active Directory because you need some central user management to manage all those permissions and certain domain policies and, you know, you minimum password complexity, etc. Well, that's a feature you can do. Now this is all emulated because it's built on Linux. They run Samba and Samba has the ability to act as a Windows domain controller and without a Microsoft server in between. So this does have that option. So you can set up user, computers, domain policies. To an extent, it's not going to be as full-featured as a full-blown Microsoft server. But if you're looking for a solution in between for maybe a small office with a few people, this is that solution that works out rather well that you can just drop in. So you combine that with the file server dimension where you control the permissions, you have the central user management, you can have these systems joining this as a domain. That's another feature that's built in to this analogy system there. And those are some of the most common ways we install it. Now I'm going to say we use the domain auth one extremely rare because pretty much most of the people, this is complementary or they just need file server access in there. So complementary to an existing Windows controller, which it can be integrated with, or they just need some basic, you know, small offices with a couple of lawyers offices seem to have a lot of these and a couple of design offices we do that we put these in where they go, you know, we're not worried. We only have like three people. You can set the permission for those three people in the office. We just need a common shared place to store all of our data, like our design files, our legal documents, and then of course have an encrypted backup that goes off site. So we have redundancy on those, or in the case of synchronization, so they can synchronize them. So when they come and, you know, load them on your laptop wherever they're traveling to and set up a, you know, remote sync option to this right here, the Synology. And once again, when you start syncing large files and you go, maybe I don't want to pay for all that storage in one of the other commercial storage providers, but those are some of the solutions on there. Most commonly, of course, it's just basically being a NAS for small business. The last thing I'm going to cover is surveillance station. This is another really popular use case for Synology, but as I stated in the beginning, when you're selecting out your NAS, you have to have something powerful off to run this. And especially with when it comes to IP cameras, having data retention on 4k cameras is doable and possible, but you have to scale out a machine that can handle the amount of days you need to hold on to that data. That being said, if you have a bunch of cameras, a bunch of 4k cameras, you also have to take into consideration that you probably don't want to use the Synology NAS for both surveillance station under a really heavy load and at the same time trying to use it for all of your users to actively back up their PCs while at the same time trying to do all the file sharing, there are some limitations. But one of the upsides of this, let's say you have a large file server that you built that is for the other four mentioned uses, so you're using as a file server and you go, you know, I'd like all my data not just to be on a raid that's on my Synology surveillance station, but backed up nightly to another NAS that's within the same building. I say within the same building because getting this much data off site can be challenging, especially with the, you know, modern 4k cameras. But if you're backing up motion only, okay, maybe that's a solution. Either way, Synology does have options for that where you can take and set this up and create redundant Synologies for your destination because maybe you really want to hold on to the data on some type of schedule for compliance or whatever your reasons are for wanting to hold that data. Sometimes, especially warehousing companies we've set these up at, they've really got some compliance things where stuff sits in your warehouse for X amount of days. They want to at least hold the footage for the amount of days based on how long that sits in there. And in some places, when it comes to commercial shipping and export import companies, there are a lot of laws around that they have to hold that data so they have to be able to track that information. Now, I'm not going to dive deep into Synology set it to many times. Synology surveillance station because the video I have on it goes a lot more in depth and it has a wide variety of camera support and it's a great system. We do deploy a lot of that and it's nice because they do have a couple add-ons including so you can display on a TV and NASA's dedicated towards setting up some knowledge surveillance station like as a dedicated box including with HDMI ports on there. So they sell special versions of their Synology that still runs the destination manager but also has the added option of that. So that's kind of my review of the NAS system. Like I said, it's been great. We've found them very reliable. We found them to fit a lot of these small businesses. It fits into a good solution for them that's very affordable, that's been very reliable and kind of easy to deploy. And having some of those tools especially like local onsite for people to have backups of their local workstations and being able to go to restore portal because I know everyone should be saving things on a NAS but especially when you deal with and we have a lot of clients that work specifically in the design field. Once their computers are set up, they're set up and they're looking for a way to back up all that configuration and full image and like I said, that Synology backup active backup which I have a video on can do full bare metal restores and it's not just about sure we have backups of the data but you know long it takes to set up a design system and all the different CAD systems and load all the details in it and get it configured the way you want it. I don't know myself but I know from designers they tell me it takes a really long time and having a full image backup on a regular even multiple times a day is possible with Synology and have it all local local and onsite so like I said it's a good solution for that.
