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?
Re needing lots of space: you can use --link-dest to make a new directory with hard links to unchanged files in a previous backup. So you end up with de-duplicated incremental backups.
But borg handles all that transparently, with rsync you need to carefully plan relative target directory paths to get it to work correctly.

Yeah Borg will see the duplicate chunks even if you move files around.
