I've been backing up to a dedicated hard disk within the same server for all my backups in case my disks fail. And as I run more and more services, the concern of disks failures grow bigger.

I'm looking for a cheapish off-site backup solution and I'm just curious what everyone does for their 3-2-1 backup solutions.

I've got a Tarsnap account backing up my especially important data every night, which is admittedly only a couple of gigabytes of scans of important documents, hard to replace files, etc. It's doing snapshot-style backup with a backup for every day in the last week, every week of the last month, every month of the last year, and the last three years. Paying less than a dollar a month for it, so it's working out.

That stuff also gets rsync'd each night onto my NAS, which has its own automated LVM snapshot system going on along the same lines, and I'm using syncthing to mirror it onto my other PCs as a final last-ditch backup (and in case I need it elsewhere). Finally, there's an external hard drive I keep manual backups on every once in a while.

Larger datasets that aren't really stuff I want to pay for on the cloud (14 TB worth) just get stored on the NAS and a drawer full of external hard drives. Not ideal, but it's just way too much data.
