What disaster recovery technique should a manufacturing company employ to quickly recover from a disaster while minimizing data loss?

• A. Replication
• B. Mirroring
• C. Incremental backups
• D. Data archiving

Answer: (B)

The best disaster recovery technique for the manufacturing company to employ is mirroring. This approach involves creating an exact real-time copy of data in a different location, ensuring that any changes made to the primary data are simultaneously reflected in the secondary location. As a result, if a disaster occurs and the primary system fails, the company can quickly switch to the mirrored copy with minimal downtime and almost no data loss.

Mirroring provides a continuous backup of data, making it particularly beneficial when immediate data availability is crucial for operations, such as in a manufacturing context. Since the mirrored data is current and actively synchronized, the company can rely on it to restore full functionality with as little disruption as possible.

In contrast, replication, while effective, may involve a delay in syncing changes, potentially resulting in some data loss. Incremental backups, on the other hand, only capture changes made since the last backup, which means if a recent event leads to data loss, more recent changes could be lost when restoring. Data archiving is primarily focused on long-term storage and retrieval of inactive data, making it less suitable for rapid recovery scenarios where immediate access to the latest operational data is essential.
