This is an automated report from the backup script running on

`hostname`.
|

|
||
Volume ${TAR_VOLUME} of the backup needs to be put in the tape drive.
|
||
Usually whoever prepared the backup leaves labeled tapes on top of the
|
||
drive itself. If there aren't any more, information about where to find
|
||
tapes and how to label them are posted on the wall by apple-gunkies
|
||
(unhelpfully obscured by a bookshelf). An online copy (which is probably
|
||
more up-to-date) can also be found in ~friedman/etc/fsf/backup.how.

The backup has been continued, so for now no further attention is required.
