Both Azure Backup and Azure Site Recovery are set up and managed by an Azure Recovery Services vault.

Whereas Azure Backup takes a one-off backup at daily intervals, Azure Site Recovery continually replicates your VM's disks to another region. In the event that you need to failover, a new VM is created and attached to the replicated disk in the paired region, as we can see in the following diagram:

As we can see from the preceding diagram, Azure Site Recovery requires a VNET and subnet in the paired region that your replicated VMs can attach to. When you set up a VM to use Site...
