SOA-C03 - Reliability and Business Continuity - Section 2.7
Follow disaster recovery procedures and select a strategy across Regions from backup and restore through pilot light and warm standby.
Compare the four DR strategies - backup and restore, pilot light, warm standby, and multi-site active/active - by their cost, recovery time objective, and recovery point objective trade-offs. Apply cross-Region replication to select the minimum-cost strategy that still meets the stated RTO and RPO requirements.
