An excerpt from the Amanda user's crontab on my amanda server:

45 0 * * 2-6 /usr/local/sbin/amdump Daily && /usr/bin/eject -q /dev/nst0 >& 
/dev/null

That's all it takes.  The '&&' will ensure that the eject command only
executes if the amdump run returns zero (meaning it completed
successfully).  The redirection of stdout/stderr into /dev/null ensures
you don't get obnoxious emails from cron following a run where there was
no tape in the drive and so nothing to eject.
