REL13-BP03: Test disaster recovery implementation to validate the implementation
Regularly test your disaster recovery procedures to ensure they work as expected and meet your defined RTO/RPO objectives. Include both technical testing and business process validation to identify gaps, improve procedures, and build confidence in your recovery capabilities.
Implementation Steps
1. Develop DR Testing Strategy
Create a comprehensive testing strategy that covers all aspects of disaster recovery.
2. Design Test Scenarios
Develop realistic disaster scenarios that test different failure modes and recovery paths.
3. Execute Regular DR Tests
Conduct scheduled disaster recovery tests with varying scope and complexity.
4. Validate Business Processes
Ensure business processes can continue during and after disaster recovery.
5. Document and Improve
Capture lessons learned and continuously improve DR procedures based on test results.
