Standard SSD: Azure Backup Failure

imagesI have been undertaking a customer deployment and thought I would share this nugget of information which may save you some time.

Standard SSD

Even though Standard SSD are now GA as per this article.  We are unable to backup VMs with Standard SSD, receiving in total two error messages.

The first error message is the initial job to configure the backup fails with the message ‘Deployment to resource group ‘name’ failed.  Additional details from the underlying API that might be helpful: At least one resource deployment operation failed.  Please list deployment operations for details.  Please see https://aka.ms/arm-debug for usage details.

Azure Backup 01

Digging a bit deeper we receive the Error Code ‘UserErrorGuestAgentStatusUnavailble’ with a recommended action of ‘Ensure the VM has network connectivity and the VM agent is update and running.  For more information, please refer to https://aka.ms/guestagent-status-unavailable’.

A quick reboot of the VM and this resolves the initial ‘configure backup error’ with Standard SSDs.

We then go to protect the VM and undertake the initial backup and this is where the problem occurs.  After two plus hours, you will receive an error notification which states ‘The storage type is not supported by Azure Backup’.

Azure Backup 02

This is a known issue and is documented in the ‘Prepare Resource Manager Deployed VMs‘ article under the section ‘Limitations when backing up and restoring a VM’.

So for now, you can deploy VMs with Standard SSD but you can’t back up the entire VM using Azure IaaS VM Backup!

Update

Azure Backup now supports Standard SSD see blog post here.
