Recovery drill reveals configuration drift

Short summary

A quarterly recovery drill exposed configuration drift, not backup failure. Three silent changes—service endpoints, CA rotations, security policies—accumulated in the recovery environment while the backup stayed consistent. Before drills, verify six specific gaps: endpoints, trust chains, network policies, DNS, secrets, and storage paths.

• •Backup integrity alone does not guarantee recovery success; recovery environments accumulate configuration drift independently
• •Three drift vectors caused application failure: service endpoint changes, CA trust path rotations, and security policy tightening
• •Pre-drill validation must check six failure modes: endpoints, cert chains, ACLs, DNS, secrets, and storage paths
