Azure Backup Server: Unprotected servers still showing up in the Azure portal even though their protection was stopped 3 months ago

To help protect your hybrid backup setup with an Azure Backup Server (MABS), Microsoft introduced some security features built on three principals – Prevention, Alerting and Recovery. These features are enabled by default for newly create Recovery Services vaults, for existing vaults this link will show you how you can enable them. One of these features related to recovery will ensure you that Azure backup will retain all deleted backup data for 14 days, which ensures you can recover data using any old or recent recovery point(s).


Sometime ago I reconfigured a Protection Group which protected some Hyper-V VMs. Two Domain Controllers (DCs) were taken out of the Group and setup to only backup the C drive and the System State. On the MABS server all configuration went well and did not cause any specific issues or errors. However last week when I was checking the Recovery Services vault used to store the cloud backups,I noticed those two DCs were still showing up in the Backup items overview.


Like you can see, those two VMs are still there with no Disk or Cloud Recovery Points created after the protection was disabled.


To get the issue fixed, I followed some standard steps I always follow when having issues with a MABS. The first one is checking the current Azure Backup Agent version installed on the MABS, which was version 2.0.9109.0. Because there is a newer version available (at the time of writing version 2.0.9118.0), step one was getting that one in place.


To download the latest agent go to your Recovery Services vault blade in the Azure portal. Select Backup and on the Getting Started with Backup blade, select Backup goal. In the drop-down menu(s), select On-premises and Files and folders, click OK. In the Prepare Infrastructure blade, click Download Agent for Windows Server or Windows Client. Save MARSAgentInstaller.exe.



Install the latest agent on the MABS server. After the agent installation completes restart the following service:

Microsoft Azure Recovery Services Management Agent




Although the agent is now at the latest version it still did not fix the protection status of the deleted servers in the Azure portal.

After doing a little more troubleshooting (reading the logs, etc.) , I decided to open an Azure support ticket. The support agent who assisted me, told me, just like I already suspected, that this was currently  the default behavior from the azure backup service in some Azure regions (current backend design behavior like they say). The product team was already aware of this issue and they definitively will fix it in some later update.

If you cannot wait for the update, there is a quicker fix for the issue, you just need to delete the whole MABS server from the Azure portal and reconnect the server all over again. However, for me and even more for the customer this was a no go. So, we will wait for the proper backend update which will hopefully not take that long anymore.

Hope this helps whenever you face the same backup behavior in the Azure portal with your deleted MABS backups.
