Standard Operating Procedure: Disaster Recovery Plan (DRP) Deployment

1. Document Control Block

---

2. Executive Summary & Purpose

The purpose of this procedure is to provide a standardized framework for the creation, maintenance, and execution of a Disaster Recovery Plan (DRP). This ensures organizational resilience, minimal RTO (Recovery Time Objective), and strict adherence to RPO (Recovery Point Objective) targets during catastrophic infrastructure failure or service disruption.

3. Scope & Prerequisites

• Scope: Applies to all Tier-0 and Tier-1 mission-critical infrastructure within Template Registry environments.
• Required Tools: Git-based version control, encrypted Vault/Secrets Manager (HashiCorp), automated backup orchestration (Veeam/AWS Backup), and a secondary "Warm" off-site recovery site.
• Prerequisites: Completed Business Impact Analysis (BIA) and a documented Asset Inventory List.

5. Step-by-Step Procedure

Phase 1: Preparation & Templating

• Initialize the DRP repository from the master template.
• Define RTO/RPO metrics for each business-critical application.
• Identify and catalog all external dependencies (APIs, third-party SaaS).

Phase 2: Execution & Failover

• Trigger: Verify "Disaster" status via monitoring alerts (OpsGenie/PagerDuty).
• Isolation: Sever connection between compromised segment and production environment.
• Provisioning: Execute Infrastructure-as-Code (Terraform) scripts in the secondary DR region.
• Data Recovery: Pull the latest immutable snapshot from the off-site storage.
• Verification: Run smoke tests to validate data integrity and system latency.

Phase 3: Restoration & Sign-off

• Perform DNS cutover to the DR infrastructure.
• Conduct full regression testing.
• Author Post-Mortem Report (PMR) within 72 hours of restoration.

6. Quality Assurance & Pro-Tips

Best Practices:

• Immutable Backups: Ensure backups are WORM (Write Once, Read Many) to prevent ransomware encryption.
• Chaos Engineering: Conduct quarterly "Game Day" drills where you intentionally simulate a partial outage.

Metrics & Thresholds:

• RTO Target: < 4 hours.
• RPO Target: < 15 minutes.
• Success Threshold: 100% data parity check against last known good state.

Common Pitfalls:

• Credential Rot: Ensure service account passwords for DR systems are synced in the Vault.
• Configuration Drift: If your IaC scripts haven't been run against production in 30 days, your DR will fail.

7. Frequently Asked Questions

Q: Why is my DR site showing latency higher than production? A: Typically, DR environments are provisioned as "Pilot Lights" to save cost. Scale the auto-scaling groups manually to match production capacity before traffic cutover.

Q: Can I restore from an encrypted backup if the encryption key is lost? A: No. Disaster Recovery is entirely dependent on Key Management Service (KMS) availability. Ensure keys are cross-region replicated.
