Add QoS function to SQL in a VM backup
During the Azure SQL backup of an VM, disk latency is extremely high and overloads the VM causing applications to fail. Suggested solution to resize the VM or to scatter the backup do not work. Please add a QoS function to the Azure SQL Backup to limit the load during the backup

This is very important. I have read you can use the Resource Governor inside the VM to throttle the backup, but this is only available to Enterprise (unless something has changed). We shouldnt have to upgrade a standard SQL IaaS VM from an E4s (which handles its normal workload) to an E48 just so a piece of Azure (SQL Backup for Azure VM) can talk to another part of Azure (VM disks).
