I’m running my media server with a 36tb raid5 array with 3 disks, so I do have some resilience to drives failing. But currently can only afford to loose a single drive at a time, which got me thinking about backups. Normally I’d just do a backup to my NAS, but that quickly gets ridiculous for me with the size of my library, which is significantly larger than my NAS storage of only a few tb. And buying cloud storage is much too expensive for my liking with these amounts of storage.
Do you backup only the most valuable parts of your library?
I do not backup my media. When my zfs blows up, i need to start getting everything back again. I can live with it, it is nothing important. Thanks to sonarr/radarr etc, my media will recover itself over time anyway.
Important stuff is backed up at least twice locally and 1 times off side.
