DR Testing and Validation Guide

Tabletop exercises, simulation tests, and full failover testing — how to validate your DR plan

Executive summary

DR testing validates that recovery plans work as documented and RTO/RPO objectives can be achieved. DR plans that have never been tested consistently fail during actual disasters.

Key takeaways

This guide covers the essential concepts, best practices, and decision frameworks for DR Testing and Validation Guide.
DCS Global engineers have deep expertise in this area across national and international projects across North America, Europe, Asia-Pacific, and the Middle East.

Overview

DR testing levels: tabletop exercises (discuss response to hypothetical scenarios), simulation tests (test specific procedures without full failover), full failover tests (actually fail over to DR site).

Key Concepts

Tabletop exercise: Discussion-based, no systems affected. Simulation test: Test specific procedures without full failover. Full failover test: Actually fail over and verify operations. Failback test: Return to primary after failover.

Best Practices

Conduct tabletop exercises quarterly. Simulation tests semi-annually. Full failover tests annually for critical systems. Document results and remediate gaps. Measure actual RTO and RPO.

Key Considerations

Full failover tests carry risk — plan carefully and have rollback procedures. Some systems cannot be tested without impacting production. DR testing reveals gaps that documentation reviews miss.
