Disaster recovery testing validates that systems and data can be restored within defined RTO and RPO objectives. It covers multiple testing methods from simple checklist reviews to full-scale failover exercises, and highlights what modern DR tests must evaluate: backup integrity, application dependencies, infrastructure recovery, identity/access, and automation scripts. A practical Python script example shows how to automate post-restore validation for a PostgreSQL database. Common DR test scenarios include accidental deletion, data corruption, ransomware simulation, infrastructure outages, and credential failures. The post advocates integrating DR testing into CI/CD pipelines and treating it as a continuous practice rather than an annual compliance checkbox.
