Which disaster recovery technique replicates primary systems in real-time to minimize downtime?

• A. Backup
• B. Failover
• C. Mirroring
• D. Redundancy

Answer: (C)

The correct answer is mirroring because this technique involves replicating data in real-time or near real-time, which ensures that an exact copy of the primary system is maintained at all times. This allows for rapid switching to the mirrored version in the event of a failure, thereby minimizing downtime. Mirroring is typically used in environments where data integrity and availability are critical, allowing organizations to continue operations seamlessly even when the primary system is compromised. In the context of disaster recovery, mirroring is particularly effective because it enables organizations to maintain an up-to-date replica of their data and systems, ensuring that the most recent transactions and changes are preserved. This capability is vital for businesses that require constant access to their information and can't afford interruptions—such as financial institutions, healthcare providers, and any organization that relies heavily on real-time data. Other techniques like backup involve creating copies of data at specific intervals, which can lead to data loss if an issue occurs after the last backup but before a failure. Failover refers to switching to a standby system when the primary system fails, but it usually does not focus on real-time replication. Redundancy, while important in disaster recovery, refers to having extra components or systems in place to take over in case of failure, but it
