A friend has kindly allowed me to store a hard drive at his house to use as an offsite backup. I normally use rsync-backup to make backups of my home directory and have always done this (just being lucky!) to 2 separate USB drives. This has been great but the chance of a house fire has always terrified me. My previous job let me keep a drive in a desk drawer but wouldn't allow it to be connected to the network. It was such a pain to bring it home every few weeks and rsync that laziness prevailed. My friend's ONE request is that the drive be encrypted so there's no chance of privacy issues -- either him reading my files, or him being somehow liable for anything that might be on the drive.
I have googled a LOT about this topic but the problem is that most of the whole drive encryption walk throughs are for an OS. Not a remote drive. I am hoping that someone out there knows how to set this up so that (ideally) a cron job can run at a regular time nightly or maybe weekly, updating everything from the drive at my house onto the one at his place. He has high speed cable, so it shouldn't be problematic to do this and I'm going to FIRST do the initial rsync at home...then give him the drive, he'll install it at his place and give me access via a unique server, and hopefully things will go from there.
Thank you for any and all help with this project. If this is easily answered somewhere, please let me know where -- I've done tons of searches and just can't find the right keywords to get the info I want. I end up just getting to pages for making LUKS volumes within an OS...and I either don't understand how that's the answer or else it's NOT the answer.
I should add that I'm avoiding Cloud-based options because of expense. I have about 6TB of data (I'm a photographer/videographer working with very large files over decades...) and I just can't afford the fees involved with typical cloud storage. Even if I could, I would want to know how to ensure the data's encrypted and how to do regular automated backups. But this option to have my own hard drive at a friend's place seems awesome.
Again, thank you! :-)
