Overview

Cloud DR models: backup and restore (lowest cost, highest RTO), pilot light (core infrastructure pre-deployed), warm standby (scaled-down environment running continuously). DRaaS providers: Zerto, VMware Cloud DR, AWS CloudEndure.

Key Concepts

DRaaS: Managed DR service handling replication, failover orchestration, and testing. Replication: Continuous copying to cloud DR target. Failover: Activating cloud DR when primary fails. Failback: Returning to primary after recovery.

Best Practices

Test cloud DR failover quarterly. Verify recovery time from cloud DR. Implement immutable backup in cloud DR. Document failback procedures.

Key Considerations

Cloud DR recovery time depends on internet bandwidth. Egress costs during failover can be significant. Regulated industries must verify data residency requirements. DRaaS pricing models vary.
