### First we'll delete old files
       0 15 * * 5 if test -f /disk3/backup_from_pc/*.*; then rm
       /disk3/backup_from_pc/*.*; fi       

### Maggi, what have we done( for last week)?
         0 16 * * 5 find /disk3 \( -name '*.BDU' \) -mtime -7 -exec cp {}
         /disk3/backup_from_pc/{} \;

### And now we are coping all our information to the tape drive
         0 17 * * 5 /usr/sysadm/privbin/backup -c recurring-990698733 -i
         'backup_from_pc' -v -n -f /dev/tape -m euclid -s 
         /var/sysadm/backups/recurring-990698733
