Extending an existing SnapMirror relationship to the cloud

Contributors netapp-forry netapp-aherbin

To back up an existing SnapMirror relationship to the cloud, you identify volumes to be backed up and create NetApp Data Availability Services workflows for backup operations according to the policies you select.

Before you begin

You must have registered NetApp Data Availability Services with ONTAP secondary storage and added a cloud or StorageGRID target for a source-to-target-to-cloud workflow. Both should be visible within the Targets window.

About this task

Using NetApp Data Availability Services, you can extend existing SnapMirror secondary relationships for cloud backup. In the Data Protection window, volumes with two shields checked are ready for cloud backup.

Note: Only SnapMirror relationships of type MirrorAndVault and MirrorAll can be extended to cloud. SnapMirror relationships of type MirrorLatest cannot be extended to cloud.

Once the cloud backup workflow has been established, regular backups are performed according to the policy you selected.

In the background, NetApp Data Availability Services updates the cloud-resident catalog with metadata for all the cloud backups whenever a scheduled backup runs.

  1. In the Data Protection window, identify the volume you want to back up to the cloud.

    Volumes that are ready for cloud backup are identified with the “Backed up to disk” annotation, which indicates that a SnapMirror secondary has been created.

    If you want to protect a new volume, it might not appear in the volume display for up to 30 minutes while the volume rediscovery process is taking place.

    • In tabular view: click on the checkbox. (Tabular view is the default beginning with release 1.1.2.)

    • In tile view: hover in the upper right corner of the desired volume’s tile to display a round checkbox, then click on the checkbox.

      When you click on the checkbox, the previously greyed-out Protect button at the top of the Data Protection window is displayed.

      You can select multiple volumes to protect in this workflow. All the volumes that are selected should already be backed up to a disk target.

  2. Click the Protect button.
    The existing protection strategy for the source-to-target replication is automatically recognized and displayed. This is not changed by the NetApp Data Availability Services operation.

    Existing default and custom backup policies are displayed.

  3. Select the displayed backup policy and click Protect.
    Backup to cloud is initiated for the volumes indicated. The initial SnapShot copy backup is a full backup; subsequent backups are incremental, as between the SnapMirror source and target targets.

    When the backup has begun, the Data Protection window with all available volumes is displayed, and the status of the newly initiated backup is updated. The overall status can also be monitored on the Dashboard window.
