Example—Performing an Incremental Backup of root (`/`)

The following example shows how to do an incremental backup of the root (/) file system. The following ufsdump options are included:

9 specifies that this is a 9 level dump (or an incremental backup)
u specifies that the /etc/dumpdates file is updated with the date of this backup
c identifies a cartridge tape device
f /dev/rmt/0 identifies the tape device
/ is the file system being backed up

# ufsdump 9ucf /dev/rmt/0 /
  DUMP: Writing 63 Kilobyte records
  DUMP: Date of this level 9 dump: Fri Jul 13 10:58:12 2001
  DUMP: Date of last level 0 dump: Fri Jul 13 10:46:09 2001
  DUMP: Dumping /dev/rdsk/c0t0d0s0 (starbug:/) to /dev/rmt/0.
  DUMP: Mapping (Pass I) [regular files]
  DUMP: Mapping (Pass II) [directories]
  DUMP: Mapping (Pass II) [directories]
  DUMP: Mapping (Pass II) [directories]
  DUMP: Mapping (Pass II) [directories]
  DUMP: Estimated 200 blocks (100KB).
  DUMP: Dumping (Pass III) [directories]
  DUMP: Dumping (Pass IV) [regular files]
  DUMP: Tape rewinding
  DUMP: 124 blocks (62KB) on 1 volume at 8 KB/sec
  DUMP: DUMP IS DONE
  DUMP: Level 9 dump on Fri Jul 13 10:58:12 2001
