This solution applies to the Barracuda Backup Agent when in use with Windows  2008/2012/2016.


In some cases, you may experience issues with snapshot backups, and the Windows Event logs may show a message like: 

The shadow copies of volume C: were deleted because the shadow copy storage could not grow in time. 
Consider reducing the IO load on the system or choose a shadow copy storage volume that is not being shadow copied.
