4 Types of Disaster Recovery Tests You Need to Know | Resilience Testing | Harness

Your production system will fail. The question is whether you'll know how to bring it back up.

Disaster recovery testing is the third pillar of resilience testing, alongside load testing and chaos engineering. But most teams don't know there are actually 4 distinct types of DR tests, each with different risk levels and complexity.

This video breaks down the complete DR testing ladder: tabletop exercises where teams talk through recovery plans, simulation tests that execute real recovery steps in safe environments, parallel testing that runs backup systems alongside production, and full interruption tests that completely cut over to disaster recovery sites.

Whether you're building resilience into microservices, cloud infrastructure, or distributed systems, understanding these DR testing approaches helps you validate recovery plans without gambling with uptime.
