ProcedureHow to Use ufsdump to Perform Backups

You can perform full or incremental backups using the ufsdump command. This procedure backs up the zone /export/my-zone to /backup/my-zone.ufsdump, where my-zone is replaced with the name of a zone on your system. You might want to have a separate file system, for example, a file system mounted on /backup, to hold the backups.

  1. Become superuser, or assume the Primary Administrator role.

    To create the role and assign the role to a user, see Using the Solaris Management Tools With RBAC (Task Map) in System Administration Guide: Basic Administration.

  2. (Optional) Shut down the zone to put the zone in a quiescent state and to avoid creating backups of shared file systems.

    global# zlogin -S my-zone init 0
  3. Check the zone's status.

    global# zoneadm list -cv

    You will see a display similar to the following:

    ID  NAME     STATUS       PATH                           BRAND      IP
     0  global   running      /                              native     shared
     -  my-zone  installed    /export/home/my-zone           native     shared
  4. Perform the backup.

    global# ufsdump 0f /backup/my-zone.ufsdump /export/my-zone

    You will see a display similar to the following:

    DUMP: Date of this level 0 dump: Wed Aug 10 16:13:52 2005
    DUMP: Date of last level 0 dump: the epoch
    DUMP: Dumping /dev/rdsk/c0t0d0s0 (bird:/) to /backup/my-zone.ufsdump. 
    DUMP: Mapping (Pass I) [regular files]
    DUMP: Mapping (Pass II) [directories]
    DUMP: Writing 63 Kilobyte records
    DUMP: Estimated 363468 blocks (174.47MB).
    DUMP: Dumping (Pass III) [directories]
    DUMP: Dumping (Pass IV) [regular files]
    DUMP: 369934 blocks (180.63MB) on 1 volume at 432 KB/sec
  5. Boot the zone.

    global# zoneadm -z my-zone boot
