🛡️ DISASTER RECOVERY PLAN

Information System Resilience Strategy

🎯 Goal: Minimize downtime, data loss & financial impact

🔵 1. The Recovery Team (Who)

Role Responsibility
Incident CommanderDeclares disaster, authorizes plan activation
IT Recovery LeadManages technical restoration (servers, network)
Communications LeadInternal updates & external PR/customer comms
Security OfficerEnsures physical & cyber security during recovery
Liaison OfficerCoordinates with vendors, law enforcement & legal

🟠 2. Risk Assessment (Why)

⚠️ Common Threats:

⚡ Power Outage 🌊 Natural Disaster 💀 Cyberattack 🔌 Hardware Failure 🦠 Pandemic / Human Error

📊 Business Impact Analysis (BIA):

  • Critical (Tier 1): ERP, Customer DB, Payment Gateways
  • Important (Tier 2): Email, Internal File Shares
  • Low (Tier 3): Dev environments, Archive logs

🟢 3. Recovery Strategies (How)

🏢 Recovery Sites

Hot Site: Fully operational duplicate — RTO: Minutes

Warm Site: Partially equipped — RTO: Hours/Days

Cold Site: Empty facility with power — RTO: Weeks

💾 Backup Types

Full: Complete copy of all data

Incremental: Changes since last backup

Differential: Changes since last full backup

Snapshot: Instant point-in-time copy

📏 Key Metrics

RTO (Recovery Time Objective): How long can we be down? (e.g., 4 hours)

RPO (Recovery Point Objective): How much data can we lose? (e.g., 15 mins)

🔴 4. The Recovery Process (Timeline)

Phase 1 · 0–1 Hour

Detection & Activation

Monitor alerts → Assess severity → Decision: Activate DRP?

Phase 2 · 1–2 Hours

Notification & Mobilization

Alert Recovery Team → Notify stakeholders → Redirect traffic to backup site

Phase 3 · 2–24 Hours

Restoration & Recovery

Restore from latest clean backup → Rebuild infrastructure → Verify integrity

Phase 4 · 24–48 Hours

Validation & Return

Test functionality (QA) → Failback to primary site → Monitor stability

Phase 5 · 1 Week Later

Post-Mortem

Document lessons learned → Update DRP based on gaps found

🟣 5. Communication Plan

  • Internal: Slack/Teams channel, SMS alerts, Emergency hotline
  • External: Press release, Customer status page (status.company.com)
  • Regulatory: Notify compliance bodies if data breach occurred (GDPR/HIPAA)

🟡 6. Testing & Maintenance

  • Tabletop Exercise: Discussion-based walkthrough (Quarterly)
  • Simulation: Test failover to backup site (Bi-Annually)
  • Full Interruption Test: Shut down primary site (Annually)
  • Review: Update contact lists & software versions (Monthly)
