Example--Performing a Full Backup, Individual Home Directory

The following example shows how to do a full backup of the /export/home/kryten directory. The following ufsdump options are included:

  • 0 specifies that this is 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

  • /export/home/kryten is the directory being backed up

# ufsdump 0ucf /dev/rmt/0 /export/home/kryten
  DUMP: Writing 63 Kilobyte records
  DUMP: Date of this level 0 dump: Fri Jul 13 11:30:45 2001
  DUMP: Date of last level 0 dump: the epoch
  DUMP: Dumping /dev/rdsk/c0t3d0s7 (pluto:/export/home) to /dev/rmt/0.
  DUMP: Mapping (Pass I) [regular files]
  DUMP: Mapping (Pass II) [directories]
  DUMP: Estimated 232 blocks (116KB).
  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

Example--Performing a Full Backup to Remote System (Solaris 9 Data to Solaris 9 System)

The following example shows how to do a full backup of a local /export/home file system on a Solaris 9 system (starbug) to a tape device on a remote Solaris 9 system (earth).The following ufsdump options are included:

  • 0 specifies that this is 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 earth:/dev/rmt/0 identifies the remote system name and tape device

  • /export/home is the file system being backed up

# ufsdump 0ucf earth:/dev/rmt/0 /export/home
  DUMP: Writing 63 Kilobyte records
  DUMP: Date of this level 0 dump: Wed Sep 05 14:52:31 2001
  DUMP: Date of last level 0 dump: the epoch
  DUMP: Dumping /dev/rdsk/c0t0d0s7 (starbug:/export/home) to earth:/dev ...
  DUMP: Mapping (Pass I) [regular files]
  DUMP: Mapping (Pass II) [directories]
  DUMP: Estimated 266 blocks (133KB).
  DUMP: Dumping (Pass III) [directories]
  DUMP: Dumping (Pass IV) [regular files]
  DUMP: Tape rewinding
  DUMP: 250 blocks (125KB) on 1 volume at 247 KB/sec
  DUMP: DUMP IS DONE
  DUMP: Level 0 dump on Wed Sep 05 14:52:31 2001
