This operation copies data from RV to MV.
It is performed to restore data from the backup volume (RV) when a failure occurs in MV.
When Restore is executed, the RV contents at the point of starting Restore are reflected copied into the
MV. At this time, you can determine whether to reflect the updated data of the MV into the RV by
choosing either of the following:
• Restore with RV being updated: Restore(update)
Restores the MV while automatically reflecting the updated data of the MV into the RV. Even after
the difference between MV and RV is resolved and Restore is completed, any data update made to
MV is reflected to RV.
• Restore without RV being updated: Restore(protect)
Restores the MV without reflecting the updated data of the MV into the RV. After the difference
between MV and RV is resolved and Restore is completed, Separate is automatically executed. The
Restore(protect) function enables you to save the RV data in the state before the restoration.
The product DynamicDataReplication Ver2 or RemoteDataReplication Ver2 is necessary for using
the function.
