78This is an automated report from the backup script running on 
79`hostname`. 
80
81Volume ${volno} of the backup needs to be put in the tape drive.  Usually
82whoever prepared the backup leaves labeled tapes on top of the drive
83itself.  If there aren't any more, information about where to find tapes
84and how to label them are posted on the wall by apple-gunkies (unhelpfully
85obscured by a bookshelf).  An online copy (which is probably more
86up-to-date) can also be found in ~friedman/etc/fsf/backup.how.
