Replication
Replication is the process of copying recovery points and transmitting them to a
secondary location for the purpose of disaster recovery. The process requires a
paired source-target relationship between two cores. Replication is managed on a
per-protected-machine basis; meaning, backup snapshots of a protected machine
are replicated to the target replica core. When replication is set up, the source core
asynchronously and continuously transmits the incremental snapshot data to the
target core. You can configure this outbound replication to your company’s own
data center or remote disaster recovery site (that is, a “self-managed” target core) or
to a managed service provider (MSP) providing off-site backup and disaster recovery
services. When you replicate to an MSP, you can use built-in workflows that let you
request connections and receive automatic feedback notifications.

Replication 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.
