I am setting up a very basic storage-only NAS box for myself and my parents. It will have two mirrored disks, and will be accessed locally by me and via Tailscale by my parents. That is the extent of the requirements and setup I have done so far.
the server is currently running Truenas Scale, and is working just fine, with one exception - the drives are on all the time, and I sleep in the same room. From what I can tell, there is no easy way to get Truenas to spin down drives, and this server will spend most of its time inactive anyway.
Long story short, am I stupid for considering a basic Debian install instead? Frankly, I could probably run Windows and have easy access to Backblaze, too.
Go for it if your complexity is two mirrored disks. Anything seriously important stick it into a directory to be backed up off-site with incremental backups or however you'd prefer to sort that out.
