Restoring Azure VMs Using the HotAdd Transport Mode

By default, Azure VMs with the disk size greater than 8TB are restored by DirectUploadtoManaged disk for full VM and attach disk restores; however, this approach does not allow you to restart the restores. To restart the Azure VM restores, you can use the HotAdd transport mode by adding the bAzurePreferHotAddRestoreForLargeVM entity setting.

With HotAdd transport mode, virtual disks from the Azure virtual machines that are being backed up will be mounted to the access node. This will allow the access node to access virtual disks as local disks.

Backups You Can Use for Restore

• Backup copy

• Streaming copy

Supported Operations

• In place and out of place full VM restores

• Disk attach restores

• Conversion from Hyper-V to Azure and VMware to Azure

Prerequisites

• At least one disk size of the VM must be greater than 8TB.

• Verify that the access node is in the same subscription, same region, and same availability zone of the destination VM.
