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?

    The software borgbackup does some insane compression.

    It is more effective if you backup multiple machines tbh (my 3 linux computers with ~600gb used each get compressed down to a single ~350gb backup, because most of the files are the same programs and data over and over again)

    But it might do a decent enough job in your case.

    So one of the solutions might be getting a NAS and setting up borgbackup.

    You could also get a second one and put it in your parents or best friends home for an offsite backup.

    That way you don’t have to buy as large of a drive capacity, but will only have fixed costst (+electricity) instead of ongoing costs for some rented server storage.

    I guess that would be about 400$ per such a device, if you get a used office pc and buy new drives for it.

    Tape seems to be about half the price per TB, but then you need special reader/writer for it, which are usually connected via SAS and are FUCKING EXPENSIVE (over 4000$ as far as I can see).

    It only outscales HDDs in price after like ~600TB

      How do you handle the cache invalidation issue with Borg when backing up multiple systems to one repo? For me if I access a Borg repository from multiple computers (and write from each) it has to rebuild the cache each time which can take a long time.
