Disaster Recovery
The restoration of technology systems and data after a major disruptive event.
In simple terms
Disaster recovery is how a business brings essential systems back after an outage.
Technical explanation
Recovery plans define backups, restoration steps, dependencies, and target times and data-loss tolerances.
Recovery concerns rebuilding technology and data to an acceptable state after serious disruption. Sequence matters: identity, network, application, and data dependencies may need restoration in a particular order.
Examples in practice
After server damage, a company rebuilds from tested backups in a separate environment.
The company restores its identity service before the payroll application because staff cannot access payroll without it. A rehearsal exposes a missing encryption key, which the team adds to its recovery plan.
Why it matters
A written plan needs restoration practice to be dependable.
