The process of copying data to remote locations, and then keeping the replicated data synchronized with the primary data. Data replication is distinct from data distribution. Replicated data is stored copies of data at one or more remote sites throughout a system, and it is not necessarily distributed data. Contrast with data distribution. See also disk replication and transaction replication.
The act of copying data transactions to another location, usually as a preventive measure.
The copying of data to and from sites to improve local service response times and availability; frequently employed as part of a backup and recovery strategy.
Data replication refers to a data storage and backup strategy that copies data from a host computer to another computer, which may or may not be at a remote location. Replication over a computer network can make data backup entirely independent of local data center physical storage.
