Hat was mit den Backup-Werkzeugen dump/restore zu tun

man dump:

[...]
-0-9 Dump levels.  A level 0, full backup, guarantees the entire file system
	 is copied (but see also the -h option below).  A level number above 0,
	 incremental backup, tells dump to copy all files new or modified since
	 the last dump of the same or lower level. The default level is 9.

[...]														 

-W Dump tells the operator what file systems need to be dumped. This
   information is gleaned from the files /etc/dumpdates and /etc/fstab. The -W
   option causes dump to print out, for each file system in /etc/dumpdates the
   most recent dump date and level, and highlights those file systems that
   should be dumped. If the -W option is set, all other options are ignored, 
   and dump exits immediately.

-w Is like W, but prints only those filesystems which need to be dumped.

und das ist der Output den IRIX liefert:

 0-9 This number is the dump level.  All files modified since the last date
	 stored in the file /etc/dumpdates for the same filesystem at lesser
	 levels are dumped.  If no date is determined by the level, the
	 beginning of time is assumed; thus the option 0 causes the entire
	 filesystem to be dumped. For instance, if you did a level 2 dump on
	 Monday, followed by a level 4 dump on Tuesday, a subsequent level 3
	 dump on Wednesday would contain all files modified or added to the
	 filesystem since the level 2 (Monday) backup.  A level 0 dump copies
	 the entire filesystem to the dump volume.
