Scheduled volume encrypt decrypt

[jacoporicci]

Hello, I was wondering if something like this exists:

 

I want to do offsite backups of my nas on a server I've set up at the office.

The problem is that we already had a breach by thieves and I want to have the volumes in that server encrypted in case they get stolen.

I don't care about the drive itself but I don't want my private data to be accessible by a thief.

 

What I was thinking about is some sort of a software that can encrypt a volume and then decrypt it if a certain condition is satisfied to make it accessible by the backup software that can use it as a destination drive.

I was thinking about making a script that reads a key that I store here at home and if it can read that key then it unlocks the volume. So in case they steal the drivers I can just delete that key and if they reconnect to the internet the script doesn't see that key and doesn't unlock the software.

 

To make this i need something I can control via command line, but since I only know a scripting language called AutoIt i will just be replicating a user typing command so I was looking for a premade solution that can do this.

Is there something around there?

 

Thanks and sorry for the long post.
