I am currently working on an Azure project that involve creation of new VM and migration from VMware on-premises VM.
Part of the project is to configure Azure Backup for the VM.
I had some issue with migrated servers and will provide here after some more information
I created Backup Policy based on customer expectation and then tried to deploy on all my servers.
However part of the servers were migrated server from on-premises and on those servers the deployment failed.
I need to troubleshoot the deployment failure.
I get the message UserErrorGuestAgentStatusUnavailable – VM agent unable to communicate with Azure Backup
Searching on Internet I find this interesting article: https://docs.microsoft.com/en-us/azure/backup/backup-azure-troubleshoot-vm-backup-fails-snapshot-timeout
In my case the information provided in this article are the following:
UserErrorGuestAgentStatusUnavailable – VM agent unable to communicate with Azure Backup
Error code: UserErrorGuestAgentStatusUnavailable
Error message: VM Agent unable to communicate with Azure Backup
The Azure VM agent might be stopped, outdated, in an inconsistent state, or not installed and prevent Azure Backup service to trigger snapshots.
- If the VM agent is stopped or is in an inconsistent state, Restart the Agent and retry the backup operation (try an ad-hoc backup). For steps to restart the agent, see Windows VMs or I Linux VMs.
- If the VM agent is not installed or is outdated, install/update the VM agent and retry the backup operation. For steps to install/update the agent, see Windows VMs or Linux VMs.
So here are the steps to fix this:
- Open Web browser and go to https://go.microsoft.com/fwlink/?LinkID=394789&clcid=0x409, save and run
- Click on Next
- Accept the license agreement and click on Next
- Click on Finish
After few moment, the service will starts and we can configure Azure Backup on those servers.
Feedback
I am really surprised that Microsoft does not include this tool as part of the migration process.
However it’s not time consuming to download and install it and it does not required a server reboot.
You just need to ensure to do this on your migrated server if you want to enable Azure Backup on those servers.
