Overview
DR encompasses the plans, processes, and technology required to restore IT operations after a disruptive event. Key metrics: RTO (how quickly must systems be restored?) and RPO (how much data loss is acceptable?).
Key Concepts
RTO: Maximum acceptable time to restore IT operations. RPO: Maximum acceptable data loss. DR site: Secondary location for restoration. Hot site: Fully operational with real-time replication. Warm site: Partially configured. Cold site: Empty facility.
Best Practices
Define RTO and RPO for each critical system before selecting DR strategy. Test DR plans annually. Document DR procedures in detail. Ensure DR plans account for ransomware scenarios.
Key Considerations
DR is expensive — cost must be justified by cost of downtime. Not all systems require the same DR tier. Cloud DR provides geographic diversity without secondary data center investment.
