Example—Performing a Full Backup of root (`/`)

The following example shows how to do a full backup of the root (/) file system. The system in this example is brought to single-user mode before the backup. The following ufsdump options are included:

0 specifies a 0 level dump (or a full 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.

For example:

# init 0
ok boot -s
# ufsdump 0ucf /dev/rmt/0 /
  DUMP: Date of this level 0 dump: Tue Oct 07 16:23:08 2003
  DUMP: Date of last level 0 dump: the epoch
  DUMP: Dumping /dev/rdsk/c0t0d0s0 (starbug:/) to /dev/rmt/0.
  DUMP: Mapping (Pass I) [regular files]
  DUMP: Mapping (Pass II) [directories]
  DUMP: Writing 63 Kilobyte records
  DUMP: Estimated 296644 blocks (144.85MB).
  DUMP: Dumping (Pass III) [directories]
  DUMP: Dumping (Pass IV) [regular files]
  DUMP: Tape rewinding
  DUMP: 296224 blocks (144.64MB) on 1 volume at 424 KB/sec
  DUMP: DUMP IS DONE
  DUMP: Level 0 dump on Tue Oct 07 16:23:08 2003
