Validating Backup Integrity for Recovery
When to Use
Use this skill when:
- Verifying backup integrity before relying on backups for ransomware recovery
- Building automated backup validation pipelines that run after each backup job
- Auditing backup infrastructure to confirm recoverability for compliance (SOC 2, ISO 27001, NIST CSF RC.RP-03)
- Detecting silent data corruption (bit rot) in backup storage before a disaster occurs
- Validating that immutable or air-gapped backups have not been tampered with
Do not use for initial backup configuration or scheduling. This skill focuses on post-backup validation.
Prerequisites
- Access to backup storage (local, NAS, S3, Azure Blob, GCS)
- Python 3.9+ with
hashlib(standard library) - Backup manifests or baseline hash files for comparison
- Isolated restore environment for restore testing
- Backup tool CLI access (restic, borgbackup, rclone, or vendor-specific)
