Learn the failover and failback stages in Site Recovery on Azure. Learn Business Continuity and Disaster Recovery (BCDR) strategy in Azure.
Failover and failback in Site Recovery has four stages
Stage 1: Fail over from on-premises: After setting up replication to Azure for on-premises machines, when your on-premises site goes down, you fail those machines over to Azure. After failover, Azure VMs are created from replicated data.
Stage 2: Reprotect Azure VMs: In Azure, you reprotect the Azure VMs so that they start replicating back to the on-premises site. The on-premises VM (if available) is turned off during reprotection, to help ensure data consistency.
Stage 3: Fail over from Azure: When your on-premises site is running as normal again, you run another failover, this time to fail back Azure VMs to your on-premises site. You can fail back to the original location from which you failed over, or to an alternate location.
Stage 4: Reprotect on-premises machines: After failing back, again enable replication of the on-premises machines to Azure.
