- # Modifications by P. E. Cantrell to level-1 for a level-2
- # floppy disk dump. The level-2 dump will backup everything
- # since the most recent tape or floppy disk level-1 dump or
- # level-0 tape dump.
- # Added new files $fsname.level-1-floppy and $fsname.level-2-floppy
- # for use with level-2 floppy disk backups. We rewrite *.level-1-floppy
- # whenever we do a tape level-0 backup or a tape or floppy level-1
- # backup. $fsname.level-2-floppy would be used for a level-3 backup
- # if you wrote one.
