I have a folder of MP3s, some of which date back to 1999, just a few years after the format was popularised. Most of them have utterly terrible names (think RIDEONAM.MP3). I think at this point they might even survive the heat death of the universe. And they’ll still be terribly-organised.
RAID1 combined with a separate backup drive on a different machine (Raspberry Pi with a USB->SATA drive bay works). ZFS with EEC RAM helps a lot, too (as another poster mentioned).
No, it’s not a full 3-2-1 backup solution, but you have to spend quite a bit as a data hoarder to actually get that. As far as I can tell, few data hoarders actually have a 3-2-1 backup without squinting about the details. Having any backup is better than no backup.
