Azure Site Recovery is an Azure service that can help organizations protect their data and workloads by providing business continuity and disaster recovery services. This service helps ensure that your VM workloads remain available even in the event of a planned or unplanned outage. Azure Site Recovery consists of several steps, namely Replication, Failover, Re-protect, and Failback. On Azure Stack HCI clusters running the May 2023 cumulative update of version 22H2 and later, it is possible to replicate your on-premise Azure Stack HCI virtual machines into Azure to protect your critical workloads. You can then create recovery plans within Azure that allow you to failover and recover the VMs in Azure if there is an outage on your Azure Stack HCI cluster. Once the outage is corrected, you can fail back the VMs to the Azure Stack HCI cluster.
