Data Replication is the process of creating and maintaining copies of data from a source system or database in one or more target systems or locations to ensure data availability, redundancy, and disaster recovery capabilities. Data replication techniques include full replication (copying entire datasets), partial replication (selective replication of specific tables or records), synchronous replication (real-time replication with immediate consistency), asynchronous replication (delayed replication with eventual consistency), and bidirectional replication (synchronization of changes between source and target systems). Data replication is commonly used for data distribution, data sharing, high availability, fault tolerance, and disaster recovery purposes in distributed systems and databases.
