What is the expected outcome of synchronous replication in a disaster recovery context?

In a disaster recovery context, synchronous replication ensures that data written to the primary site is simultaneously written to the backup site in real-time. This means that both locations hold identical data at any given moment. As a result, the expected outcome is that the data remains current in the backup, allowing for minimal data loss in the event of a failure or disaster. This capability is vital for organizations that require high availability and cannot afford to lose any in-flight transactions or data changes, as the backup is effectively an exact mirror of the primary site.

Synchronous replication is often contrasted with asynchronous replication, where there may be a delay between writing to the primary and the secondary storage, potentially resulting in outdated data residing in the backup until it synchronizes. Therefore, in this context, the option stating that the data remains current in the backup accurately reflects the primary benefit of synchronous replication technology.
