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.
What would you do?
I just want to add, you may not need to backup what you think you can redownload easily.
There are cases of series or movies being really difficult to find or it takes you a long time to find a working torrent. For those it definitely should make sense to back them up, but its a bit subjective feeling which ones those might be.
Another thing in my case, I got movies and seriea for my child on the server. He expects that is accessible, always, and is too young to understand that data can get lost. So I am also backing that up, it could be easily replaced but it would take me time and this would result in my child being unhappy. Not worth it!
