Replication is the copying of data from one system or site to another to protect against loss and support recovery or availability. In data centers it runs synchronously for zero data loss over short distances or asynchronously across longer distances, and underpins disaster recovery, high availability and geographic redundancy. It keeps a secondary copy aligned with the primary.
