how much backing up would you do of a media server?
I have a nas with 2x10tb drives. I mostly just have music, movies and tv shows on it.
People talk about raid not being a backup, but is that relevant for non-original data? I mean I can always get the media again if need be. It would just be an inconvenience.
I only back up my music collection because I put extra effort into organising and tagging everything, plus some of it is rips of CDs not available anywhere. As for movies and TV shows, I only back up configurations and catalogues of the relevant apps, the contents themselves are 1) too big to be feasible to back up and 2) 99% of the time available to re-download.
This is how I do it. I have all my media on a raid 5 tho. Broken hdds are unavoidable in the long run, so I want protection for that. If something goes sideways at rebuilding, so be it. Most of the movies and shows I'm wondering what I save them for anyways. My music collection is worth more to me and backed up properly. Same goes for my personal stuff.
I have the equivalent of RAID 5 too, but mind the usual "RAID is not a backup" - if you deliberately delete something (or something goes wrong with an app managing your media), hardware redundancy won't save you in any way; it only helps if the data is intact and you want to remedy a hardware failure.
