After creating and attaching volumes, you can implement data protection by creating incremental snapshots.

You can use the Snapshot method if you don't need continuous copying but want to schedule the copy depending on expected changes in the data.

Note: For volumes on the following storage systems, you can create snapshots by accessing Storage Advisor Embedded:

VSP E series
VSP G/F350, G/F370, G/F700, G/F900

The snapshot creation process creates the secondary volume on a snap pool. If there is more than one snap pool, the least-used snap pool is used.

Note: To create snapshots outside of Ops Center Administrator for a volume that is in Ops Center Administrator, use a new snapshot group.

In the Protect Volumes window, select the volumes you want to protect, then click Snapshot.
Enter a number from 1 to 1024 in the Snapshot Retention Policy (Max 1024) field to specify the number of snapshots to be created.
When the specified number of snapshots is reached, older snapshots will be deleted as new ones are added. The maximum number of snapshots that can be retained is 1024.
You can enable Consistency to perform data protection on all pairs in the group simultaneously.
Consistency acts as a filter for replication groups, so your choice might affect the availability of replication groups.
Set an hourly, daily, weekly, or monthly schedule. A volume cannot have more than one schedule. The schedule is based on UTC time.
- Hourly: Select a start time in minutes after the hour, and the number of hours between snapshots to start creating snapshots at the selected time and interval.
- Daily: Select a start time, available in five minutes increments, to start a snapshot every day at the selected time.
- Weekly: Select a start time and a day to create a snapshot every week at the selected date and time. You can select more than one day to create more than one weekly snapshot.
- Monthly: Select a start time and the day of the month (from 1 to 31) to create a snapshot one time a month at the selected day and time.
In Volumes to be Protected, select a Replication Group for each volume or select Use New and enter a name for the new replication group in the Replication Group Name. Up to 26 alphanumeric characters, hyphens (-), and underscores (_) are allowed. Spaces are not allowed.
(Optional) Select the pool from the list of available pools. The default selection is Auto Selected, which means that Ops Center Administrator selects the best pool based on utilization and tier requirements.
If you choose a Thin (DP) pool or a Snap (HTI) pool, the replication technology used will be Snap on Snap, unless there is already a Snap volume created in an earlier version of Ops Center Administrator. In that case, the replication technology used will continue to be Snap.
Click Submit.

A summary message is displayed, and snapshots are created according to the schedule. The replication group can be viewed on the Replication Groups window.
