You can use ONTAP System Manager classic (available in ONTAP 9.7 and earlier) to create and manage Snapshot policies in your storage system.

About Snapshot policies

When applied to a volume, a Snapshot policy specifies a schedule or schedules according to which Snapshot copies are created and specifies the maximum number of Snapshot copies that each schedule can create. A Snapshot policy can include up to five schedules.

For vault relationships, the SnapMirror Label attribute is used to select Snapshot copies on the source volumes. Only Snapshot copies with the labels configured in the vault policy rules are replicated in backup vault operations. The Snapshot policy assigned to the source volume must include the SnapMirror Label attribute.

Create Snapshot policies

You can create a Snapshot policy in System Manager to specify the maximum number of Snapshot copies that can be automatically created and the frequency of creating them.

Steps

  1. Click Protection > Snapshot Policies.

  2. Click Create.

  3. In the Create Snapshot Policy dialog box, specify the policy name.

  4. Click Add, and then specify the schedule name, the maximum number of Snapshot copies that you want to retain, and the SnapMirror label name.

    The maximum number of Snapshot copies that can be retained by the specified schedules must not exceed 254.

  5. Click OK, and then click Create.

Edit Snapshot policies

You can modify the details of an existing Snapshot policy, such as the schedule name, SnapMirror label, or the maximum number of Snapshot copies that are created, by using the Edit Snapshot Policy dialog box in System Manager.

Steps

  1. Click Protection > Snapshot Policies.

  2. In the Snapshot Policies window, select the Snapshot policy that you want to modify and click Edit.

  3. In the Edit Snapshot Policy dialog box, select the schedule that you want to modify and click Edit.

  4. Click OK.

  5. Verify the changes you made to the selected Snapshot policy in the Edit Snapshot Policy dialog box and click Save.

Delete Snapshot policies

You can use System Manager to delete Snapshot policies. If you delete a Snapshot policy that is being used by one or more volumes, Snapshot copies of the volume or volumes are no longer created according to the deleted policy.

Before you begin

You must have dissociated the Snapshot policy from each volume that uses it.

Steps

  1. Click Protection > Snapshot Policies.

  2. Select the Snapshot policy and click Delete.

  3. Select the confirmation check box, and then click Delete.

Snapshot Policies window

You can use the Snapshot Policies window to manage Snapshot policy tasks, such as adding, editing, and deleting Snapshot policies.
