I’m considering getting a NAS device to act as media server/hub for movies, pictures, etc. I’m also looking to backup files from multiple computers (2 laptops and 1 desktop) that are on my home LAN. The question I have is does it make sense to use a single NAS device for both purposes? To me, that seems a little risky, if the NAS goes down for whatever reason then I lose my backups. Is it better to dedicate the NAS as media server only and have a separate NAS for backup?
