HPE Primera Remote Copy synchronization
Remote Copy performs either full synchronization or delta resynchronization on the volumes in a Remote Copy group.
- Full synchronization
Copies the entire source Remote Copy group to the secondary storage system.
Initial synchronization of the volumes in a Remote Copy group is always a full synchronization. Initial synchronization occurs when you create a Remote Copy group and select Initial Sync. Full synchronization of the volumes also occurs when you select the Sync action in a Remote Copy group.
- Resynchronization
Copies only the data that changed since the previous synchronization. Resynchronization occurs based on the replication mode.
