Creating a new SnapMirror relationship and cloud backup

Contributors netapp-forry netapp-aherbin

Using NetApp Data Availability Services (NDAS), you can create new SnapMirror relationships between the ONTAP source and the ONTAP target storage, and then extend them to the cloud.

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.

About this task

In the NDAS app Data Protection window, volumes with one shield checked (indicating local Snapshot copies only) or with no shields checked (no local Snapshot policy in place) are ready for the source-to-target-to-cloud backup workflow. NetApp Data Availability Services will apply the default local Snapshot policy if none exists for a volume.

Once the source-to-target-to-cloud backup workflow has been established, regular backups are performed according to the default NDAS policy.

In the background, the NDAS app updates the cloud-resident catalog with metadata for all the cloud backups whenever a scheduled backup runs. This metadata includes information on the data objects that were backed up, including file and volume names, timestamps of backups, and capacity of the data objects.

  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 “Local snapshots” annotation, which indicates that only SnapShot copies are available on the source cluster and a SnapMirror target relationship has not yet 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 and actionable.
      You can select multiple volumes to protect in this workflow.

  2. Click the Protect button.

    The Protection Strategy for the workflow appears, consisting of a set of default secondary locations, cloud locations, and backup policies are displayed. Details about default and other available policies can be found in the Policies window.

  3. Verify the displayed defaults, then click Protect.

    Backup is initiated for the volumes indicated. The initial Snapshot copy backup from source to target and from target to cloud is a full backup; subsequent backups are incremental.

    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. Progress of the backup can be monitored on the Activities window, and overall status of the data protection environment is shown in the Dashboard window. When the backup is complete all three shields for the volumes are displayed green in the Data Protection window.
