Replication

Replication is the process of copying or duplicating data, tasks, or activities from one system or location to another, ensuring consistency and reliability. In computing, it means copying data from a primary server to a backup server so that the information is maintained in multiple places. This helps prevent data loss in case of failures and allows for easier access or recovery. Essentially, replication ensures that multiple copies of information stay synchronized, providing stability, fault tolerance, and availability across systems or locations.
