Mirror and vault relationships

You can use Storage Manager to create and manage mirror and vault relationships by using the mirror and vault policy.

  • Creating a mirror and vault relationship from a destination SVM
    You can use Storage Manager to create a mirror and vault relationship from the destination storage virtual machine (SVM) . Creating this relationship enables you to better protect your data by periodically transferring data from the source volume to the destination volume. It also enables you to retain data for long periods by creating backups of the source volume.
  • Deleting mirror and vault relationships
    You can use Storage Manager to end a mirror and vault relationship between a source and destination volume, and release the Snapshot copies from the source volume.
  • Editing mirror and vault relationships
    You can use Storage Manager to edit a mirror and vault relationship by modifying the selected policy or schedule. However, you cannot edit the parameters of an existing policy or schedule.
  • Initializing mirror and vault relationships
    You can use Storage Manager to initialize a mirror and vault relationship if you have not already initialized the relationship while creating it. When you initialize a relationship, a complete baseline transfer of data is performed from the source volume to the destination.
  • Updating mirror and vault relationships
    You can use Storage Manager to manually initiate an unscheduled incremental update. You might require a manual update to prevent data loss due to an upcoming power outage, scheduled maintenance, or data migration.
  • Quiescing mirror and vault relationships
    You can use Storage Manager to quiesce a destination volume to stabilize the destination before creating a Snapshot copy. The quiesce operation enables active data transfers to finish and disables future transfers for the mirror and vault relationship.
  • Resuming mirror and vault relationships
    If you have a quiesced mirror and vault relationship, you can resume the relationship by using Storage Manager . When you resume the relationship, normal data transfer to the destination volume is resumed and all the protection activities are restarted.
  • Breaking mirror and vault relationships
    You can use Storage Manager to break a mirror and vault relationship if a source volume becomes unavailable and you want client applications to access the data from the destination volume. You can use the destination volume to serve data while you repair or replace the source volume, update the source volume, and reestablish the original configuration of the systems.
  • Resynchronizing mirror and vault relationships
    You can use Storage Manager to reestablish a mirror and vault relationship that was broken earlier. You can perform a resynchronization operation to recover from a disaster that disabled the source volume. For Infinite Volumes, the resynchronization operation recovers the volume and its constituents.
  • Reverse resynchronizing mirror and vault relationships
    You can use Storage Manager to reestablish a mirror and vault relationship that was previously broken. In a reverse resynchronization operation, the functions of the source and destination volumes are reversed. You can use the destination volume to serve data while you repair or replace the source, update the source, and reestablish the original configuration of the systems.
  • Aborting mirror and vault relationships
    You can abort a volume replication operation if you want to stop the data transfer. You can abort a scheduled update, a manual update, or an initial data transfer.
  • Restoring a volume in a mirror and vault relationship
    You can use Storage Manager to restore Snapshot copies to a source volume or to other volumes if the source data is corrupted and is no longer usable. You can replace the original data with the Snapshot copies in the destination volume.
