Site Recovery is a service that keeps corporate apps and workloads operational during outages, assuring smooth business processes. This feature offered by Azure works in such a way that it copies activities from a primary location to a secondary location with the help of physical and virtual machines (VMs). When your primary location goes down, you switch to the secondary location, where you can access the apps. You can roll back to the principal location once it has been restored. Site Recovery ensures replication for Azure VMs, on-site VMs, Azure Stack VMs, and physical servers.
