During the restoration phase of a disaster recovery operation, an organization is preparing to restore multiple critical systems. Which of the following approaches represents the BEST strategy for system restoration?
Restore systems with the latest technology first
Restore systems based on the priority list outlined in the disaster recovery plan
Restore systems that are less damaged first to achieve early recoveries
Restore critical systems concurrently to minimize business downtime
The correct answer is to restore systems based on the priority list outlined in the disaster recovery plan. During restoration, organizations should follow a structured approach based on business impact analysis (BIA) results and recovery time objectives (RTOs) that were established during DR planning. This ensures that the most critical business functions are restored first.
Restoring systems with the latest technology first ignores the actual business criticality of each system. Restoring less damaged systems first might be easier but doesn't align with business priorities. Restoring critical systems concurrently would overwhelm available resources, causing inefficiencies and possibly extending the overall recovery time for truly critical systems.
