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?
Short answer: figure out how much of that is actually irreplaceable and then find a friend or friends who’d be willing to set aside some of their storage space for your backups in exchange for you doing the same.
Tailscale makes the networking logistics incredibly simple and then you can do the actual backups however you see fit.
