Replication may use any of a number of methodologies including mirroring or shadowing, and may be performed synchronous, asynchronous, or point-in-time depending on the technologies used, recovery point requirements, distance and connectivity to the source database, etc. Replication can if performed remotely, function as a backup for disasters and other major outages.
