Episode 25 — Disaster Recovery Purpose: Restore IT Services Fast and Validate the Return
This episode introduces disaster recovery as the focused effort to restore IT systems and data after an outage or major disruption, and it clarifies how disaster recovery differs from broader business continuity. You will learn how disaster recovery emphasizes technical restoration activities such as rebuilding servers, restoring backups, failing over to alternate infrastructure, and confirming services function correctly after recovery. We will define recovery time objective (RTO) and recovery point objective (RPO) in practical terms and explain why these metrics matter in CC-style questions. You will practice identifying disaster recovery needs in scenarios like ransomware recovery, major hardware failure, cloud region outage, or data corruption that requires restoration to a known-good state. Real-world examples will include validating backup integrity, documenting recovery steps in runbooks, and ensuring recovery actions do not reintroduce the original failure through misconfiguration or incomplete patching.
