Personally, I back up everything on my NAS except my movie library, because that is something I can relatively easily restore by just downloading buying it again, and because it’s of course the biggest chunk of data. For the other data, I’m using a very affordable Hetzner server auction system with a lot of disks in a striped array. This gives me the maximum amount of storage, and given that I can just create the backup again should the stripe fail, I’m not worried about redundancy on the backup itself.
