How should an organization test and validate its disaster recovery plan to ensure it actually works during a real event?
AdvancedAnswer
Effective disaster recovery testing involves regularly performing actual failover drills, not just reviewing documentation, using tools like AWS Fault Injection Simulator to intentionally introduce failures and validate that automated recovery mechanisms behave as expected, and documenting clear runbooks with defined roles and responsibilities so that during a real event, the response is well rehearsed and confusion is minimized.
