Before you start

·        Azure user account needs permission to enable replication of an Azure VMS

·        Subscription should be enabled to create VMs in the target location you want to use as DR region.

Creating the Recovery vault.

Log in to the Azure portal Click New > Monitoring & Management > Backup and Site Recovery.

Add a name to identify the vault, select subscription, create a resource group or use an Exciting One. Specify an Azure region

If you want to quickly access the vault from the dashboard, click Pin to dashboard and then click Create.

Enable replication

In Recovery Services vaults, click the vault name. In the vault, click Replicate button on the top.

 

Configure Source

Select Azure - PREVIEW in the Source.Select the source Azure region where the VMs are currently running.Select VM Deployment model Resource Manager or Classic.Select the Source resource group of the VMs.

After all this configuration  Click Ok.

Virtual machines

When clicked Ok it automatically moves the VM selection 

In my case i have an IIS Server  that i will replicate as you can see in the above image.

After Selecting VM Click OK for the Next step.

Configure settings

By default, Site Recovery automatically creates settings in the target location using settings that are configured in the source location, including a target resource group, storage accounts, virtual network, and availability sets (all are created with the suffix asr).

Click Customize to override the default target settings and specify the settings of your choice.

Customize target resources

In case you want to change the defaults used by ASR, you can change the settings based on your needs.

1. Customize: Click it to change the defaults used by ASR.
2. Target resource group : You can select the resource group from the list of all the resource groups existing in the target location within the subscription.
3. Target Virtual Network: You can find the list of all the virtual network in the target location.
4. Availability set : You can only add availability sets settings to the virtual machines which are a part of availability in source region.
5. Target Storage accounts:

By default, Site Recovery creates a replication policy that takes app-consistent snapshots every 4 hours, and retains recovery points for 24 hours. To create a policy with different settings, click Customize next to Replication Policy.

To Customize Click Replication policy  Customize

Click Create target resources to start provisioning. It should take a minute or so. Don't close the blade during provisioning, or you'll need to start over.
