The transfer phase in RecoverPoint is the replication process in which host writes are sent from the source RPA to the target RPA after the “Write Phase” has taken place.  The transfer phase occurs differently depending on the consistency group settings.  I will go over the most common replication used in RecoverPoint the Non-Distributed Group setting.

After the source RPA’s have processed the data they send the data to the target RPA’s across the WAN

The target RPA’s receive the data and writes them to the target journal volumes

Once the writes have been successful to the journal the target RPA’s send an acknowledgment to the source RPA’s.

As you can see replication for Non-Distributed Groups is quite simple.  The next blog will cover Asynchronous Distributed Groups Replication
