Disaster recovery
Recovery readiness is demonstrated, not declared.
Exercises reveal whether the people, access, dependencies and technical steps in a recovery plan are actually ready to work together.
Choose the exercise for the question
A tabletop discussion can test decisions, contacts and assumptions without moving production workloads. A restore test can validate a selected copy and application. A controlled failover exercise can examine a broader transition. These exercises provide different evidence and should not be described as equivalent.
Define the scope, success criteria and safety boundaries before starting. A limited database restore may be useful, but it cannot prove that the entire business can operate from a recovery environment. Make the untested parts visible in the results.
Test the difficult dependencies
Include access to credentials, network configuration, encryption keys, supplier support and business approval. A technically correct procedure can fail if the person executing it cannot sign in or the required external support contact is no longer valid.
Where appropriate, ask a trained backup person to follow the documented steps. If they need undocumented help at every stage, the exercise has found a knowledge dependency. Record that finding without turning the test into a blame exercise. The purpose is to improve the capability.
Close the loop after the exercise
Record timings, outcomes, deviations and evidence. Assign each gap an owner and follow-up date, then repeat the relevant portion after changes. Review the plan when applications, providers, staff or business priorities change. An old successful exercise does not establish readiness for a materially different environment.
In practice
The recovery account depends on the failed identity service
Illustrative scenario, not a client case study.
In a hypothetical logistics company, a tabletop exercise assumes the primary identity service is unavailable. The team discovers that access to the recovery console normally relies on that same service. The backup data exists, but the documented access path is not independent.
- The exercise records the circular dependency and identifies the recovery-console owner. The team does not improvise by broadly disabling authentication controls in production.
- The responsible administrators design and approve a protected emergency-access method supported by the provider. They establish storage, monitoring and review procedures for that access.
- A controlled follow-up exercise verifies the access path and a scoped restore. The results distinguish what was tested from other recovery dependencies that still need validation.
The first exercise was valuable precisely because it found a failure. Readiness improved when the dependency was addressed and the correction was tested, not when the plan was marked complete.
What to put in place
- Define the scope and success criteria of each exercise.
- Test access, people and suppliers as well as restoration steps.
- Record gaps with owners, dates and supporting evidence.
- Repeat relevant tests after corrections and significant changes.
The takeaway
A credible readiness statement says what was tested, when it was tested and what remains unproven. That is more useful than an unsupported promise of seamless recovery.
