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?

      Just want to note here:

      Snapshots are NOT a backup.

      While btrfs is quite stable corruption/disk failure can always happen. Bcachefs had a little opsie daisy that caused some FS level corruption. Snapshots won’t help in this case.

      Snapshots are great for quick restoration on user error.

        bcachefs is very early tho, and the corruption was reversible becuase of the COW nature, but i agree

      Helpful yes, but far from enough. It only helps in some scenarios (like accidental deletes, malware), but not in many others (filesystem corruption, multiple disks dying at once due to e.g. lightning, a bad PSU or a fire).

      Offsite backup is a must for data you want to keep.
