I agree. ...and it really comes down to specifics.
I think that home & small office file servers should be mirrored and
snapshotted. Consumer grade kit is so cheap, I can't see a reason not to.
If I somehow came into possession of real server hardware and decided to
use it at the house, I'd redeploy an older (cheap) desktop with a couple of
large sata drives to act as a backup server, i.e. something to rsync to, and
create snapshots of the data.
