Add an RCG 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 from the replication consistency group (RCG) to the policy.

1. On the menu bar, click Protection > RCGs.
2. From the RCGs list, select the desired RCG, and click More Actions > Add 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 Rules area, 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.
8. In the Snapshot Policy was successfully added dialog box, click Assign volume to snapshot policy.
