How to Configure the Azure Restore Proxy Appliance Size
Purpose
Challenge
Attempting to restore a Linux workload fails to Microsoft Azure when using a proxy appliance size that is not available for subscriptions that have VM size limitations.
The following error may be found in:
C:\ProgramData\Veeam\Backup\AzureAppliance.Job.Azure_Helper_Appliance_Deployme.log
The requested VM size for resource 'Following SKUs have failed for Capacity Restrictions: Standard_D2lds_v5' is currently not available in location 'japanwest'. Please try another size or deploy to a different location or different zone. See https://aka.ms/azureskunotavailable for details. (Veeam.Backup.AzureAPI.CAzureWebException)
Cause
The error shown occurs when the helper appliance size Veeam Backup & Replication attempted to create is not available.
When performing Restore to Azure for Linux workloads, a helper appliance is used. That helper appliance's VM size is selected using a sizing algorithm based on the region associated with the Microsoft Azure Compute account. However, the helper appliance deployment may fail if the selected VM size is unavailable for the subscription selected within the Helper Appliance Configuration.
Solution
No workaround is available for earlier versions.
The following registry setting overrides the automatic sizing algorithm and uses the specified VM size for the helper appliance.
Create the following registry value on the Veeam Backup Server:
Key: HKEY_LOCAL_MACHINE\SOFTWARE\Veeam\Veeam Backup and Replication
Value Name: AzureApplianceRmVmSizeOverride
Value Type: String Value (REG_SZ)
Value Data: standard_d2s_v3 (example value, an empty string is the default value)
Notes:
- No reboot or service restart is required.
- The setting must be applied before adding the Microsoft Azure Compute account.
If the Azure Compute account has already been added, it must be readded to force redeployment of the helper appliance using the VM size specified.
