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 have to say that I was really surprised that apparently there isn’t a general solution for gluing together different-sized drives in an array reasonably-efficiently other than Synology’s Hybrid RAID. I mean, you can build something that works similarly on a Linux machine, but there apparently isn’t an out-of-the-box software package that does that. It seems like the kind of thing that’d be useful, but…shrugs
I think unRAID does that. But I never looked into it much tbh.
