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?
4 bay nas 22tb drives = 88tb as a single volume. Backed up to offline single storage drives that are timestamped. Anything newer than that timestamp gets rsynced/robocopied to a new drive until it’s full., update timestamp, swap drive and rinse repeat. If a drive fails, just replace it and copy the contents of the backup drives to master and restored. Alternatively you can set a single disk tolerance raid.
