There is one particular file in a user's OneDrive that keeps failing to be backed up. It is a OneNote file and the size is about 3.8 GB.

The error in the Job Log is:
System.Exception: Throttling error happened after maximum retries at LibCvOneDrive.CvOneDrive.<PartialDownloadForUrl>d__198.MoveNext()

 

And the more detailed log:

Hi Sidi,

From log lines it looks like this OneNote file is being throttled by Microsoft. Please check if the file is constantly open or being modified which could be the reason why file access is being throttled. 

Also, I would suggest you to open a ticket with the Support team to review and troubleshoot this further. You can do this from Metallic Support Portal.

Thanks for your response Gnana. I did open a ticket with Metallic Support but they said the issue is with Microsoft not Metallic. I will check with the user about the file being open all the time.
