Backup and restore
A successful backup job shows that a process completed. It does not by itself show that required records can be restored, accessed, related, and interpreted. Define the record population, attachments, metadata, audit trail, electronic signatures, relationships, configuration, retention, encryption keys, retrieval method, restoration environment, and data-protection controls used during testing.
Disaster recovery
Define the approved recovery requirement, accountable supplier and customer responsibilities, recovery environment, system dependencies, data and configuration recovery, identity and interface recovery, verification, deviations, business workaround, reconciliation, return to service, and conclusion. Use applicable system, recovery, and continuity requirements; do not invent separate validation requirements only because disaster recovery testing occurs.
Completed fictional exercise
A supplier reports that the eQMS database backup completed. The customer’s annual recovery exercise restores a representative environment and retrieves CAPA records, attachments, audit history, signatures, and linked changes. Records are present, but the signing certificate needed to interpret legacy signature detail is missing and the outbound training interface resumes from an old checkpoint, producing duplicate messages.
The exercise remains unsuccessful for the defined use. The team restores the certificate chain, corrects the interface checkpoint procedure, repeats retrieval and duplicate-prevention checks, reconciles queued transactions, and documents the actual recovery time and retained limitations before approving closure.
Regulatory and procedural context
Primary sources. 21 CFR Part 11 ↗ addresses protection and ready retrieval of records in scope. EU GMP Annex 11 ↗ addresses business continuity and data availability for applicable GMP systems.
Company procedure. The organization’s approved validation, change-control, supplier-management, information-security, data-integrity, records-retention, and Quality approval procedures determine the required records, roles, and approval route.
CSVtoCSA practitioner interpretation. Recovery evidence should show that regulated records and required process functions remain usable and meaningful, not only that infrastructure restarted. This is a recommended validation approach, not a statement that every listed activity is a direct regulatory requirement.
