How should I do backups? (sh.itjust.works)

I have a server running Debian with 24 TB of storage. I would ideally like to back up all of it, though much of it is torrents, so only the ones with low seeders really need backed up. I know about the 321 rule but it sounds like it would be expensive. What do you do for backups? Also if anyone uses tape drives for backups I am kinda curious about that potentially for offsite backups in a safe deposit box or something.

TLDR: title.

Edit: You have mentioned borg and rsync, and while borg looks good, I want to go with rsync as it seems to be more actively maintained. I would like to also have my backups encrypted, but rsync doesn't seem to have that built in. Does anyone know what to do for encrypted backups?

I have a machine at my parents’ house that has a single 20TB drive in it. I’ll log in once in a while and initiate an rsync to bring that up to current with my RAID at home. The specific reason I do it manually is in case there’s a ransomware attack. I won’t copy bad data. That’s also the reason I start it from the backup machine. The main machine doesn’t connect, the backup machine does, so ransomware wouldn’t cross that virtual boundary.

I would like to replicate your setup in the future. How do you connect between the two machines, using tailscale or something like that?

It’s just over ssh. They’ve both got their own subdomains.
