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 backup my /home folder on my PC to my NAS using restic (used to use borg, but restic is more flexible). I backup somewhat important data to an external SSD on a weekly basis and very important data to cloud storage on a nightly basis. I don't backup my *arr media at all (unless you count the automated snapshots on my NAS), as it's not really important to me and can simply be redownloaded in most cases.

So I don't and wouldn't apply the 321 rule to all data as it's simply too expensive for the amount of data I have and it'd take months to upload with my non-fiber internet connection. But you should definitely apply it to data that's important to you.
