I assume the problem is unauthorized recovery of not-my-data ?

...but if a random user has login access to the server and there are
default settings on the tape drive ?

You can code the crontab line that runs amdump to offline the tape
after amdump completes, then if the tape drive is in a protected
computer room you are all set. This has been documented in the
amanda-users list. Something like

        amdump config && mt -f /dev/tape offline

Might be a little trickier with a jukebox or something that can load
a tape. Perhaps changing protections on the drive to 770 for either
the amanda user or whatever group its in.

As far as access to generic data online, its whatever your normal
access and protections are.
