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?
My library is not nearly as large as yours but I’ve got the things that i can get back over time like movies and shows and stls and I’ve got the things that i can’t get back cached elsewhere.
