BMR is a right direction to take when backing up VMs in Azure. You won't get access to VM snapshots with backup software, hence the requirement to back them up from within the VM itself.
The above applies to use cases when you a) must use NBU and b) need to make application-aware backup or take backup data out of Azure, for example to store it in AWS, on-premises or elsewhere. If there is no requirement to access backup data but just to have backup orchestration and you can afford to store backups Azure ($$) - have a look at Veritas CloudPoint which is available at Azure Marketplace - it's a cloud snapshot orchestration tool that supports Azure
