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.
