Full volume restore using MARS console stuck at Estimating size of Backup items...

Question

Hi, I've been attempting to start a full volume recovery from MARS, however it has been stuck at "Estimating size of Backup items..." for 24 hours and I believe there is nothing currently in progress.

Additionally, on the Backup jobs blade in portal.azure.com it appears as the restore is still running:

For context, the full backup is around 2.68TB, and about 600k files.

There are no logs on the Windows Event Viewer computer where MARS is running.

Could someone please point me to the right direction to further troubleshoot this?

Hello @FCQ Thank you for contacting us through Microsoft Q&A platform. Sorry for the inconvenience caused to you!

It sounds like you're encountering some challenges with your Azure Backup recovery process. Please follow the suggestions below and see if this helps:

1. First thing, please ensure that you are running the latest version of MARS agent [Version. 2.0.929] - download it from here or from the Azure portal as mentioned in this section.

If you are already using the latest version of MARS agent, there are a few things you can try to resolve the issue:

2. Since you mentioned that the restore job still appears to be running in the Azure portal, try cancelling the job from there if possible. Sometimes, jobs can get stuck on the MARS agent side but still appear as running in the portal. Cancelling the job from the portal might help to resolve the issue.
3. If cancelling the job doesn't work or if you're unable to cancel it from the portal, try restarting the Microsoft Azure Recovery Services (MARS) agent service on the machine where it's installed. This might help to reset the agent and allow you to start a new recovery job.
4. Check the status of the Azure Backup Agent service:

• Open the Services console on the server where the Azure Backup Agent is installed.
• Verify that the service is running and set to start automatically.
  • If the service is not running, start it and try the backup again

5. Check the status of the Volume Shadow Copy service:

• Open the Services console on the server where the backup is being taken.
• Verify that the Volume Shadow Copy service is running and set to start automatically.
  • If the service is not running, start it and try the backup again.

6. If none of the above steps resolve the issue, try restarting the backup.

If the issue persists after trying these steps, you may need to contact Azure technical support for further assistance.
