Veeam version is 6.5
In Windows 2012
I created the same two online backup jobs, one of the backup jobs allocation two Hyper-V virtual machines, two Hyper-V virtual machines belong to the same disk.
Perform the same two backup jobs at the same time, Three virtual machine backup successfully, a virtual machine failure.
Unable to create snapshot(Hardware Provider)(mode:Crash consistent).Details:Failed to create VSS snapshot set.Another shadow copy creation is already in progress. Wait a few moments and try again.--tr:Failed to perform pre-backup task;
Is it right? Veeam is not support this kind of scene.
