Note: With Global Deduplication, the Rapid Recovery Replication process is self-optimizing with a unique Read-Match-Write (RMW) algorithm that is tightly coupled with deduplication. With RMW replication the source and target replication service matches keys before transferring data and then replicates only the compressed- encrypted- deduplicated data across the WAN resulting in a 10x reduction in bandwidth requirements.
Note: Bandwidth that ISPs specify is typically the total available bandwidth. All devices on the network share the outgoing bandwidth. Make sure that there is enough free bandwidth for replication to accommodate the change rate or apply some QoS policy on your router or firewall device in order provide dedicated bandwidth for replication.
