Restore backups in an air-gapped or network-segmented lab, then verify data integrity with file counts, SHA-256 hashes, and database consistency checks. Measure the full timeline from incident declaration to service restoration and compare actual RTO/RPO against tiered targets.

Measure RTO as the time from incident declaration (T0) to full service restoration (T4), including validation and hardening time. Measure RPO as incident time minus the backup timestamp, not the backup schedule interval.

The workflow supports Veeam Backup & Replication, Commvault, Rubrik, AWS Backup, Azure Backup, Restic, and Velero for Kubernetes. Each provides restore points that can be validated in an isolated recovery environment.

Restores fail due to corrupted incremental chains, missing application dependencies, wrong recovery sequencing, or backups encrypted by the ransomware itself. Quarterly restore testing and immutable or air-gapped backup storage prevent these failures.

No, recovery tests must run in an air-gapped or segmented lab with no routes to production, verified with ip route show. Testing on production risks spreading the infection and invalidates the test results.

Do not use it during a live ransomware attack; use dedicated incident response playbooks instead. This skill is designed for planned drills, tabletop exercises, and compliance audits, not active incident response.
