How should I do backups? - eviltoast

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?

    It is unrealiatic, that in a stable software release there is suddenly, after you tested your backup a hard bug which prevents recovery.

    How is unrealistic? Think of this:

    • day 1: you backup your files, test the backup and everything is fine
    • day 2: you store a new file that triggers a bug in the compression/encryption algorithm of whatever software you use, now backups are corrupted at least for this file Unless you test every backup you do, and consequently can’t backup fast enough, I don’t see how you can predict that future files and situations won’t trigger bugs in a software

      We talk about software that is considered stable. That has verification checks for the backup. Used by thousands of ppl. It is unrealistic.
