What term is used for real-time data copying to a remote location for recovery purposes?

The term used for real-time data copying to a remote location for recovery purposes is remote replication. Remote replication involves continuously mirroring data from a primary location to a secondary one, ensuring that up-to-date copies are maintained and can be accessed in the event of a disaster or data loss. This process is critical for organizations that require high availability and quick recovery of their data.

Remote replication typically utilizes technologies that allow for minimal data loss, as it transfers data instantly or near-instantly. This feature can significantly reduce downtime during recovery, as organizations can quickly switch to their replicated data if an outage occurs or if the primary site fails.

In contrast, the other options provided do not specifically describe the ongoing real-time aspect necessary for immediate recovery scenarios. For instance, remote backup could refer to scheduled backups that may not capture the most current state of the data at the time of failure, while data duplication can imply a one-time copy rather than a continuous, real-time process. Cloud migration involves moving data and applications to a cloud environment but does not inherently indicate the real-time copying mechanism used for recovery.
