Recovery
Restoring systems and data to normal operations after an incident or outage.
Recovery restores systems and data to normal operation after eradication, validating that they’re clean before returning to production. Two objectives drive it: RTO (recovery time objective) sets how fast service must be back, and RPO (recovery point objective) sets how much data loss is tolerable, which dictates backup frequency. DR exercises validate these procedures before a real outage tests them for the first time.
