Azure Backup already supports backup and restore of virtual machines created through the classic and Azure Resource Manager deployment models, along with Azure Premium Storage VMs. Azure Backup now supports backup and restore of virtual machines encrypted through Azure Disk Encryption.
With this release, customers can now back up VMs encrypted through either a BitLocker encryption key or a key encryption key (KEK). Customers can also back up and restore keys and secrets along with the VM. Also, users with the right permissions can perform these operations by using the Azure portal and PowerShell. So this capability can help maintain the security, privacy, and sovereignty of enterprise data throughout the backup lifecycle.
