Today I will be elaborating on that article slightly to explain a new feature that was announced last week around being able to protect Azure VM's using managed disks.

What are managed disks?
Managed disks are basically VM level disks that are managed and controlled by Azure. What this means is that when you are creating a new VM you are given an option of using an existing storage account and creating a normal disk in this location or the option of selecting a managed disk. A managed disk simplifies overall storage management and is also more reliable as its managed by Azure and will have better high availability during planned or unplanned maintenance. This can really help with making your life easier!
What is Azure Site Recovery?
As mentioned in the previous article Azure Site Recovery is used to be able to provide a business continuity disaster recovery (BC/DR) service for your IaaS VM's in Azure or on premises. ASR can also be used to migrate your on premises VM's into Azure. For further information on configuring this to protect an indivudual VM's please view the full article here: http://www.ruckcloud.ml/2018/02/using-azure-site-recovery-to-replicate.html
The new feature announced is implemented within the disaster recovery (preview) section and relates to your selections for setting up protection. You now have the option to select managed disks for replication. What this means is that you can select the manage disks that you would like to migrate to the secondary region, thus creating a fail-over copy. This also means that you will not need to select a storage account to migrate unless you still have VM's that may be located in them. Below is an image from Microsoft depicting this:
As you can see from this image, you now have the following options:
Source Managed Disk - Your original primary location VM managed disk
Replica Managed Disk - Your new replica managed disk location for protection
Replica Managed Disk Type - The type of managed disk that was initially selected
So in order to sum up this service, the advantage that this gives us is that any VM's with managed disks can easily be replicated to a secondary region through the Azure Site Recovery (preview) service without the need of managing multiple storage accounts within the target location in order to manage all of your replicated virtual machines.
