The copy process and the Veeam Backup are completed successfully when run separately?
Can you reproduce the error?
I can imagine that backup fails when copying an amount of data during the snapshotting proces, but I am not sure why that would cause a PSOD.
when run separately the copy process and the Veeam backup work like a charm. I will try to reproduce the PSOD on friday afternoon, I have scheduled a server maintenance then.
thanks for the hint to the knowledge base article. I have a single esxi host with vmware vsphere essentials. I have no distributed virtual switches or port groups defined that could cause the problem.
it seems very simmilar to the following backtrace:
