Tell me more ×  This is the scenario. I have a local server in
the office that I want to back up programmatically (via a bash
script) everyday to an external hard disk that I will bring
home.  The data in the hard disk must be encrypted.  I can see
three viable solutions for that and I am here to ask your
opinions about which one will work best for my case.  solution
1: encrypt each and every file via the backup script before
copying it on the hard disk  solution 2: encrypt the entire
volume on the HD  solution 3: buy an external hard drive that
offers hardware encryption  My goals are: * the solution should
be easy to implement * I need to be able to copy the entire
backup to HD without human intervention (only using a script) *
I need to be able to read the backup on the HD programmatically
(there shouldn't be any human entering the password) *
decrypting the files should be fairly quick * the backup written
on HD must be as reliable as possible  Thanks in advance,
