Replication is known as which continuity concept?

Replication is closely associated with the concept of fault tolerance. Fault tolerance refers to the ability of a system to continue operating properly in the event of a failure of one or more of its components. In the context of data replication, this means that multiple copies of data are stored across different locations or devices. If one copy becomes unavailable due to hardware failure, data corruption, or any other issue, the system can continue to function using the remaining copies.

By ensuring that there are multiple versions of data, replication enhances a system's resilience. This capability is essential in minimizing downtime and maintaining availability, which are critical aspects of reliable IT systems. Therefore, replication plays a vital role in implementing fault tolerance, ensuring that data integrity is maintained even during unexpected events.

Other options may relate to different facets of data management and recovery, but they do not specifically encapsulate the primary purpose of replication in terms of maintaining operational continuity.
