Step 5. Select Azure VM
At the Virtual Machine step of the wizard, select the Microsoft Azure VM where Veeam Backup for Microsoft Azure is deployed, that is, the Veeam Backup for Microsoft Azure appliance, and specify a description for future reference.
The network security group in which Veeam Backup for Microsoft Azure appliance locates must allow the Veeam Backup & Replication server to access the appliance using HTTPS. For more information on how to configure access, see Microsoft Docs.
