Snapshots enable point-in-time recovery of volumes. You can schedule for volume snapshots to be taken automatically by using snapshot policies. You can also modify a snapshot policy as needed, or delete a snapshot policy that you no longer need.

Create a snapshot policy

A snapshot policy enables you to specify the snapshot creation frequency in hourly, daily, weekly, or monthly cycles. You also need to specify the maximum number of snapshots to retain for the volume.

1. From the NetApp Account view, click Snapshot policy.

   

2. In the Snapshot Policy window, set Policy State to Enabled.

3. Click the Hourly, Daily, Weekly, or Monthly tab to create hourly, daily, weekly, or monthly snapshot policies. Specify the Number of snapshots to keep.

   Important

   For monthly snapshot policy definition, be sure to specify a day that will work for all intended months. If you intend for the monthly snapshot configuration to work for all months in the year, pick a day of the month between 1 and 28. For example, if you specify 31 (day of the month), the monthly snapshot configuration is skipped for the months that have less than 31 days.

   See Resource limits for Azure NetApp Files about the maximum number of snapshots allowed for a volume.

   The following example shows hourly snapshot policy configuration.

   

   The following example shows daily snapshot policy configuration.

   

   The following example shows weekly snapshot policy configuration.

   

   The following example shows monthly snapshot policy configuration.

   

4. Click Save.

If you need to create additional snapshot policies, repeat Step 3. The policies you created appear in the Snapshot policy page.

If you want a volume to use the snapshot policy, you need to apply the policy to the volume.

Apply a snapshot policy to a volume

If you want a volume to use a snapshot policy that you created, you need to apply the policy to the volume.

You cannot apply a snapshot policy to a destination volume in cross-region replication.

1. Go to the Volumes page, right-click the volume that you want to apply a snapshot policy to, and select Edit.

   

2. In the Edit window, under Snapshot policy, select a policy to use for the volume. Click OK to apply the policy.

   

Modify a snapshot policy

You can modify an existing snapshot policy to change the policy state, snapshot frequency (hourly, daily, weekly, or monthly), or number of snapshots to keep.

1. From the NetApp Account view, click Snapshot policy.

2. Right-click the snapshot policy you want to modify, then select Edit.

   

3. Make the changes in the Snapshot Policy window that appears, then click Save.

Delete a snapshot policy

You can delete a snapshot policy that you no longer want to keep.

1. From the NetApp Account view, click Snapshot policy.

2. Right-click the snapshot policy you want to modify, then select Delete.

   

3. Click Yes to confirm that you want to delete the snapshot policy.
