IaasVMProvider Service Stops
The service named IaasVMProvider is set to Automatic but is always at a Stopped Status.
It is normal for it to Stop when there is no backup running to conserve resources. When a backup job runs it will be started and then stop again as needed. It is part of the VMSnapshot extension which allows Azure Backup to take application-consistent backup of the VM.
