Write-order-consistent data is distributed to the replica volumes © Copyright 2009 EMC Corporation. All rights reserved. 6 RecoverPoint Remote Protection Process— CRR 1. Data is split and sent to the 2a. Host splitter RecoverPoint appliance in one of three ways 3. Writes are 6. Data is received, 7. Data is written to acknowledged uncompressed, the journal volume 2b.
