Disaster and Recovery Plan Template

Standard Operating Procedure: Disaster Recovery & Business Continuity (DRBC)

---

1. Executive Summary & Purpose

This document establishes the institutional framework for responding to catastrophic IT infrastructure failures. The purpose is to minimize Recovery Time Objective (RTO) and Recovery Point Objective (RPO) through standardized recovery workflows, ensuring data integrity and system availability during unplanned downtime.

2. Scope & Prerequisites

• Scope: Encompasses all production environments, cloud-native infrastructure, on-prem databases, and mission-critical SaaS integrations managed by Template Registry.
• Prerequisites:
  • Active Disaster Recovery site (or multi-region cloud failover).
  • Off-site encrypted backups (immutable storage).
  • Verified communication channels (e.g., PagerDuty, Slack, out-of-band VoIP).
  • Credential management (Break-glass accounts stored in hardware security modules).

3. Roles & Responsibilities (RACI)

4. Step-by-Step Procedure

Phase I: Detection & Classification

• Verify alert veracity against monitoring telemetry.
• Declare formal DR event if threshold > 15-minute outage.
• Notify all stakeholders via incident bridge.

Phase II: Isolation & Assessment

• Terminate connections to compromised/failed environments.
• Preserve forensic logs and volatile memory dumps.
• Determine data corruption vs. hardware failure vs. external attack.

Phase III: Execution (Recovery)

• Trigger Infrastructure-as-Code (IaC) deployment to clean environment.
• Restore database snapshots to the last known "Good State" (RPO).
• Validate integrity checksums of restored assets.
• Redirect DNS/Load Balancers to the recovered environment.

Phase IV: Post-Mortem & Normalization

• Transition from DR environment to primary production (if stable).
• Perform Root Cause Analysis (RCA).
• Update DR documentation based on recovery telemetry.

5. Quality Assurance & Pro-Tips

Best Practices:

• Immutable Backups: Ensure backups are air-gapped or utilize S3 Object Lock to prevent ransomware encryption.
• Infrastructure as Code: Always rebuild environments; never "repair" them during an active DR event.
• Chaos Engineering: Run quarterly "Game Day" exercises to test failover readiness.

Common Pitfalls:

• Credential Rot: Ensure break-glass passwords are tested monthly.
• Configuration Drift: Ensure DR IaC scripts are synced with production configurations.

Metric Thresholds:

• Target RTO: < 60 minutes.
• Target RPO: < 5 minutes of transaction loss.

6. Frequently Asked Questions

Q: How do we determine when to initiate a full failover?
A: Initiate a failover if the diagnostic indicates a localized outage exceeding the RTO threshold or if a catastrophic security breach occurs that renders the primary environment non-trustworthy.

Q: Where are the master encryption keys located?
A: Master keys are held in a geo-redundant Hardware Security Module (HSM). Access requires dual-authentication from the Lead Systems Engineer and the Security Officer.
