Hear, hear!
I think it's also worth mentioning that "snapshots" ala LVM, NetApp, etc,
are also *not* a backup. They help when accidentally deleting or changing
a file, nothing more. If your disk, enclosure, appliance, etc. dies,
is consumed by fire, suffers water damage, etc, the data is still GONE.
Separate physically different storage of the data is a backup. Snapshots
are useful to create a static image of the data to do the copying, but
just aren't sufficient in themselves.
