Disaster Recovery Plan

Design recovery strategies with defined objectives, tested procedures, and regular validation.

Context

You are planning disaster recovery. Define RTO/RPO requirements, design backup and failover strategies, plan testing. Read business impact analysis, current backups, and regulatory requirements.

Domain Context

Based on IT disaster recovery best practices (NIST, ISO 27031):

• RTO (Recovery Time Objective): How long can system be down? 1 hour? 1 day? Determines failover strategy.
• RPO (Recovery Point Objective): How much data loss acceptable? 1 hour? 1 day? Determines backup frequency.
• Backup Strategies: Full (complete copy), incremental (only changes since last backup), continuous replication
• Failover: Automatic (heartbeat-driven) vs manual (operations-triggered). Planned vs unplanned.
• Testing: Regular drills validate procedures; practice before disaster strikes
