This article explains how to either upload a VHD from your local machine to an Azure managed disk or copy a managed disk to another region, using AzCopy. This process, direct upload, enables you to upload a VHD up to 32 TiB in size directly into a managed disk. Currently, direct upload is supported for standard HDD, standard SSD, and premium SSD managed disks. It isn't supported for ultra disks, yet.

If you're providing a backup solution for IaaS VMs in Azure, you should use direct upload to restore customer backups to managed disks. When uploading a VHD from a source external to Azure, speeds depend on your local bandwidth. When uploading or copying from an Azure VM, your bandwidth would be the same as standard HDDs.
