Returning to the original backup and standby configuration

You can return to the original backup and standby configuration.

Steps

  1. Break the SnapMirror relationship.
  2. If the active SnapVault secondary storage system is damaged or destroyed, convert the SnapMirror destination device to an alternative SnapVault secondary system to carry on the task of backing up data from the primary storage system.

    For details on converting a SnapMirror destination to a writable volume, see the Data ONTAP Data Protection Online Backup and Recovery Guide for 7-Mode.

  3. Activate the SnapVault license on the new SnapVault system, and use the snapvault start and snapvault snap sched commands to complete configuration of the new SnapVault secondary storage system.
  4. Perform an initial SnapMirror transfer from the new SnapVault secondary volume to the new volume using the following command:
    snapmirror initialize

    Attention: Using the snapmirror initialize command will destroy all existing data on the new volumes. For details on converting a SnapMirror destination to a writable volume or qtree, see the Data ONTAP Data Protection Online Backup and Recovery Guide for 7-Mode.

    If you are able to use your original SnapVault secondary volumes as the new SnapMirror destinations and you used volume cloning to go beyond 255 Snapshot copies, which is the limit imposed on a volume by Data ONTAP, the original SnapVault secondary volumes might not be large enough to accommodate the replication. If this is the case, you can add disk space to the original SnapVault secondary volumes.
