Modify snapshot policy

PowerFlex allows you to modify the parameters of snapshot policies, when required.

1. On the menu bar, click Protection > Snapshot Policies.
2. In the list of snapshot policies, select the relevant policy, and then click Modify > Modify Policy.
3. In the Modify Snapshot Policy dialog box, change the desired parameters:
   1. In the Retention field, set 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.
   3. Optionally, clear the Read Only check box to cancel read-only access. This check box is selected by default.
   4. 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.
4. Click Modify.
5. Verify that the operation has finished successfully, and click Dismiss.
