Create a snapshot policy

Create snapshot policies with a maximum of six retention rules that each specify a retention period and number of snapshots to retain, and then add source volumes to the policy.

1. On the menu bar, click Protection > Snapshot Policies.
2. Click Create Snapshot Policy.
3. In the Create Snapshot Policy dialog box, assign the policy a name and the time interval between snapshots.
4. Create retention rules:
   1. In the Retention field, add the number of snapshots to retain.
      A retention period is created for the specified number of snapshots times the snapshot interval.
   2. Optionally, to create an additional retention rule, click Add Retention and repeat the previous step. Each rule is based on the specified number of snapshots times the previous retention period.
      Up to six retention rules can be created.
5. Optionally, clear the Read Only check box to cancel read-only access. This check box is selected by default.
6. Optionally, select the Secured check box to prevent the snapshots created by the policy from being modified or deleted before the end of the expiration date.
7. Click Create or Create and Activate to add the snapshot policy to PowerFlex.
   If created, but not activated, the snapshot policy shall be paused.
8. In the Snapshot Policy was successfully added dialog box, click Assign volume to snapshot policy.
9. In the Select volumes you wish to assign to the policy window, select one or more volumes, and click Assign Policy.
10. Verify that the operation has finished successfully, and click Dismiss.
