I can't recommend Tarsnap (https://www.tarsnap.com/ https://www.tarsnap.com/) enough for personal backups for hacker-types. Everything is encrypted client-side, so don't lose you key or thee is literally nothing you can do to get at your data again. It's also deduplicated and compressed so you can do snapshots often (on my machines I have a cron that runs every six hours) without going broke since (similar to git) you're only storing changes.

How does dedupe work with client-side encryption -- are the snapshots and diffs done on the client before encryption and upload?
- CamTin 12y ago
  Yes, exactly. The client source is available too if you like, though it's not really free software since the license still only allows you to use it with the official Tarsnap service.

    Sounds useful, I need to look for FOSS software that can do the same for local storage targets.

      As soon as I finish the client-side encryption module for Snebu, would anyone be willing to give it a quick audit? I want to make sure I'm not making any critical mistakes (I will be using external libraries, such as openssl for encryption, but still...)

I LOVE Tarsnap and use it for offsite backups for my most critical information (configuration, projects, documents, etc). For various reasons it's one of the only systems whose cryptography I trust enough to store very personal information. I think this ends up costing me about 30 cents per month. However, for things like photos the cost (as little as Colin charges) start to really add up. I do my photos on Apple and recently dumped my library into iCloud (offsite backup I guess) and then I periodically rsync that to my NAS. Photos are also backed up to Time Machine on a separate disk. I figure this gives me a fair bit of redundancy and covers me if iCloud deletes all my photos too. I've tried to do the Time Machine disk shuffling (swapping disks between home and office) but if it's not automated, it doesn't happen.
