Which technique would be best for minimizing downtime in an online store during a disaster?

• A. Load Balancing
• B. Mirroring
• C. Snapshot Backup
• D. Cloud Storage

Answer: (B)

Minimizing downtime during a disaster is crucial for an online store, as even brief periods of unavailability can lead to revenue loss and customer dissatisfaction. Mirroring is effective in this context because it involves creating an exact copy of data or systems in real-time or near-real-time. This means that if one server or data center goes down, the mirrored version can take over almost instantly, ensuring that customers can continue to access the online store without interruption.

This technique not only keeps the data synchronized between the primary and mirrored systems but also provides high availability. In the event of a disaster, failover procedures can redirect traffic to the mirrored site, allowing the business to maintain operations with little to no downtime.

Other methods, while beneficial in their own right, do not provide the same level of immediate continuity in the face of a disaster. Load balancing helps distribute traffic across multiple servers but does not inherently protect against a single point of failure, particularly if the primary site fails completely. Snapshot backups, although valuable for data protection by taking point-in-time copies, typically require recovery time that could lead to downtime during a disaster recovery scenario. Cloud storage is great for data accessibility and recovery, but the same delays in restoring services may occur, depending on the specific implementation and
