How VM Restore Works

When you run a VM restore, Veeam Backup for Microsoft Azure does the following:

1. Retrieves the configuration of each Microsoft Azure VM from the configuration database.
2. Retrieves backed-up Azure VHDs from either a backup repository or snapshot. You can select a backup source from which to perform a VM restore at the Instances step of the Restore Virtual Machines wizard.

To retrieve backed-up VHDs, Veeam Backup for Microsoft Azure uses the following APIs:

• Blob Service REST API — to retrieve managed VHDs from snapshots.

• Azure Compute API — to retrieve unmanaged VHDs from snapshots.
• Veeam VM Backup API — to retrieve managed and unmanaged VHDs from a backup repository.

For more information about managed and unmanaged VHDs in Microsoft Azure, see this Microsoft article.

3. Restores both the configuration and the VHDs of each Microsoft Azure VM to the specified Microsoft Azure subscription.
