These steps use this sample scenario:
  • Backup job performed using: mediaserver1, mediaserver2, mediaserver3, and mediaserver4
  • Restore job using only: mediaserver4
Upon completion of the restore process and resuming normal configuration, the changes made to NetBackup and DSA must be reversed to reflect the previous configuration.
  1. Make these changes for Veritas NetBackup:
    1. Open bp.conf on the master server for editing:
      /usr/openv/netbackup # vi bp.conf
    2. Enter FORCE_RESTORE_MEDIA_SERVER = media_server_performing_restore at the bottom of the file; in this example to restore using mediaserver4 only:
      FORCE_RESTORE_MEDIA_SERVER = mediaserver1 mediaserver4
      FORCE_RESTORE_MEDIA_SERVER = mediaserver2 mediaserver4
      FORCE_RESTORE_MEDIA_SERVER = mediaserver3 mediaserver4
    3. Create an empty file named: No.Restrictions, at this location on the master server:
      /usr/openv/netbackup/db/altnames # touch No.Restrictions
    NetBackup changes are dynamic, so restarting NetBackup or its services is not required.
  2. Make these changes for DSA in the BAR Setup portlet:
    1. Create a new target group to include mediaserver4.
    2. Create a restore group to map the old target group to the new target group.
    3. Create a restore job using the new restore target group.
