GxP Backup, Disaster Recovery & SOP Qualification

Regulatory Mandate (/backup-restore)

In regulated Life Sciences manufacturing, data durability and continuity are strictly audited under:

  • FDA 21 CFR § 11.10(c): Protection of records to enable their accurate and ready retrieval throughout the records retention period.
  • EU Annex 11 Clause 7 (Data Storage): Regular backups of all relevant data must be made. Integrity and accuracy of backup data and the ability to restore the data must be checked during validation and monitored periodically.
  • EU Annex 11 Clause 16 (Business Continuity): Arrangements for alternative operations in the event of a system breakdown.
  • ISPE GAMP 5 Appendix S1 (Business Continuity): Defining RTO (Recovery Time Objective) and RPO (Recovery Point Objective).

GxP Backup & Disaster Recovery Console Interface

Dual Backup Architecture

The platform governs two distinct operational backup tracks:

1. Automated Cloud Snapshot & WAL Archiving (SOP-IT-018)

  • Continuous Write-Ahead Log (WAL) streaming and daily AES-256 encrypted database snapshots.
  • Geographic replication to secondary disaster recovery data centers.
  • Write-Once-Read-Many (WORM) immutability enforcement.
  • Strict SLA thresholds:
    • Recovery Point Objective (RPO) <= 1.0 hour.
    • Recovery Time Objective (RTO) <= 4.0 hours.

2. Manual Qualified Person (QP) Dual-Custody Protocol (SOP-IT-019)

  • Applied to standalone, air-gapped laboratory analytical instruments (such as Waters Alliance HPLC EQ-HPLC-001 or benchtop mass spectrometers) that cannot run network agents.
  • Mandatory Requirements:
    1. Operator qualification verification against enterprise LMS (LMS-SOP-IT-019-QUAL).
    2. Physical WORM optical/tape media burning.
    3. Cryptographic SHA-256 hash generation of raw chromatographic sequence folders.
    4. Dual 21 CFR Part 11 digital signatures (PERFORMED_BY system operator and independent QA VERIFIED_BY).

Web Console Features

Operational Use Case Scenario Workflows

Disaster Recovery and Data Durability govern the preservation of regulated electronic records against hardware destruction, ransomware, or accidental corruption.

    DR->>UI: Initiates periodic restoration qualification drill
    UI->>Sandbox: Restores latest AES-256 cloud snapshot & WAL stream
    Sandbox-->>UI: Sandbox container active and listening
    UI->>DR_Agent: Executes 3-tier data reconciliation audit
    DR_Agent->>PG: Reconciles table row counts and schema checksums

    DR_Agent->>Qdr: Reconciles 1,536-dim vectors and payload metadata
    DR_Agent-->>UI: Asserts 100% parity; RTO = 18 min (SLA <= 4h), RPO = 0 min
    QA->>UI: Reviews reconciliation matrix & signs Part 11 certification

1. Context & Operational Pre-conditions

  • Regulatory Requirement: EU Annex 11 Clause 7 requires regular backups and periodic testing of the ability to restore data.
  • System State: Continuous WAL replication active under SOP-IT-018; target RTO is 4.0 hours, target RPO is 1.0 hour.

2. Sandbox Drill Initiation

  1. The Disaster Recovery Lead navigates to /backup-restore and opens Restoration Dry-Run Qualifications.
  2. Clicks Initiate Sandbox Drill.
  3. System pulls the most recent daily encrypted snapshot from object storage and restores it into an ephemeral sandbox environment.

3. Automated 3-Tier Database Integrity Reconciliation

The DisasterRecoveryAgent executes automated reconciliation across the three databases:

  1. PostgreSQL Relational Layer:
    • Compares row counts across all 18 tables against source database pre-snapshot metadata.
    • Result: 100% row match; zero orphan foreign keys.
  2. Memgraph In-Memory Graph Layer:
    • Verifies 505 Document nodes, 202 Asset nodes, and all topological relationships.
    • Result: Graph path traversals execute with zero integrity faults.
  3. Qdrant Vector Layer:
    • Audits 1,536-dimensional embedding collection count and payload GUIDs.
    • Result: 100% vector parity with zero missing points.

4. SLA Evaluation & QA Sign-Off

  • Achieved RTO: 18 minutes (SLA benchmark: $\le$ 4 hours).
  • Achieved RPO: 0 minutes (continuous streaming captured the final transaction commit).
  • The QA Validation Auditor reviews the reconciliation report and applies an electronic signature: I certify that the sandbox restoration dry-run successfully verified data recoverability and SLA compliance.
  • The qualification certificate is archived in PostgreSQL table restoration_drill_runs.

Scenario 2: Standalone Analytical HPLC Manual Dual-Custody Backup (SOP-IT-019)

3. WORM Media Creation & Checksum Calculation

  1. The analyst burns the raw chromatographic run folder 2026_09_SEQ_04 onto Write-Once-Read-Many (WORM) optical media.
  2. Computes the SHA-256 hash using the validated lab utility: e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855
  3. Enters the calculated hash and optical disc physical storage slot identifier (SLOT-SAFE-A12).

4. Dual 21 CFR Part 11 Electronic Signature

  1. Primary Performer: Analyst enters credentials and signs with reason PERFORMED_BY: I certify that the raw chromatographic data was copied without alteration.
  2. Secondary Verifier: Independent QA Specialist inspects the media label and hash printout, enters credentials, and signs with reason VERIFIED_BY: I have independently verified media integrity and custody documentation.
  3. Record is written to the append-only table backup_execution_ledger protected by database triggers against modification.
