And I already plan to extend my Nethserver instance to be a Plex Media Server, to host:
Videos.
Music.
Photos.
But, before add a bunch of disks in the MicroServer, I ask myself… And because raid is not a backup: How to backup such quantity of disk space?
And don’t answer another NAS
Using online backup/storage with something like backblaze or crashplan. (how are you going to manage encryption?)
Or would an USB external drive be sufficient? However, you will take some, albeit low, risk with a single disk. The chance both your server and the usbstorage dies together is very low. It might happen, for example when your house gets destroyed, but then I think you have other things to worry about when that happens.
I also think now to put two HDD with the same size in the bay on and bay 2 and only use one of them, and regulary rsync on the second one.
I know that it’s not optimal because it’s in the same machine, but it’s better than nothing, affordable…
