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?
Synology Nas(12TB raid 1)
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
Both UnraidFS and mergerFS can merge drives of separate types and sizes into one array. They also allow removing / adding drives without disturbing the array. None of this is possible with traditional RAID (or at least not without a significant time sink for re-making the array), no matter the type of RAID you use.
