When you are preparing to back up or clone a resource, you might find it helpful to view a graphical representation of all backups and clones on the primary and secondary storage.

About this task

In the Topology page, you can see all of the backups and clones that are available for the selected resource or resource group. You can view the details of those backups and clones, and then select them to perform data protection operations.

You can review the following icons in the Manage Copies view to determine whether the backups and clones are available on the primary or secondary storage (Mirror copies or Vault copies).

  • primary storage icon displays the number of backups and clones that are available on the primary storage.

  • secondary storage Mirror icon displays the number of backups and clones that are mirrored on the secondary storage using SnapMirror technology.

  • secondary vault icon displays the number of backups and clones that are replicated on the secondary storage using SnapVault technology.

    The number of backups displayed includes the backups deleted from the secondary storage. For example, if you created 6 backups using a policy to retain only 4 backups, the number of backups displayed is 6.

Note Clones of a backup of a version-flexible mirror on a mirror-vault type volume are displayed in the topology view, but the mirror backup count in the topology view does not include the version-flexible backup.

If you have secondary relationship as SnapMirror Business Continuity (SM-BC), you can see following additional icons:

  • replica site up implies that the replica site is up.

  • replica site down implies that the replica site is down.

  • relationship is reestablished implies that the secondary mirror or vault relationship has not been re-established.

Steps

  1. In the left navigation pane, click Resources, and then select the appropriate plug-in from the list.

  2. In the Resources page, either select the resource or resource group from the View drop-down list.

  3. Select the resource either from the resource details view or from the resource group details view.

    If the resource is protected, the Topology page of the selected resource is displayed.

  4. Review the Summary card to see a summary of the number of backups and clones available on the primary and secondary storage.

    The Summary Card section displays the total number of backups and clones and total number of log backups.

    Clicking the Refresh button starts a query of the storage to display an accurate count.

    If SnapLock enabled backup is taken, then clicking the Refresh button refreshes the primary and secondary SnapLock expiry time retrieved from ONTAP. A weekly schedule also refreshes the primary and secondary SnapLock expiry time retrieved from ONTAP.

    When the application resource is spread across multiple volumes, the SnapLock expiry time for the backup will be the longest SnapLock expiry time that is set for a Snapshot in a volume. The longest SnapLock expiry time is retrieved from ONTAP.

    For SnapMirror Business Continuity (SM-BC), clicking the Refresh button refreshes the SnapCenter backup inventory by querying ONTAP for both primary and replica sites. A weekly schedule also performs this activity for all databases containing SM-BC relationship.

    • For SM-BC, Async Mirror, Vault, or MirrorVault relationships to the new primary destination should be manually configured after failover.

    • After failover, a backup should be created for SnapCenter to be aware of the failover. You can click Refresh only after a backup has been created.

  5. In the Manage Copies view, click Backups or Clones from the primary or secondary storage to see details of a backup or clone.

    The details of the backups and clones are displayed in a table format.

  6. Select the backup from the table, and then click the data protection icons to perform restore, clone, mount, unmount, rename, catalog, uncatalog, and delete operations.

    Note You cannot rename or delete backups that are on the secondary storage.

    • If you have selected a log backup, you can only perform rename, mount, unmount, catalog, uncatalog, and delete operations.

    • If you have cataloged the backup using Oracle Recovery Manager (RMAN), you cannot rename those cataloged backups.

  7. If you want to delete a clone, select the clone from the table, and then click delete icon.

If the value assigned to SnapmirrorStatusUpdateWaitTime is less, the Mirror and Vault backup copies are not listed on the topology page even if data and log volumes are successfully protected. You should increase the value assigned to SnapmirrorStatusUpdateWaitTime using Set-SmConfigSettings PowerShell cmdlet.

The information regarding the parameters that can be used with the command and their descriptions can be obtained by running Get-Help command_name.

Alternatively, you can also refer to the SnapCenter Software Command Reference Guide or SnapCenter Software Cmdlet Reference Guide.
