Job log reports the following error:
V-79-40960-38690 - Backup Exec cannot export configuration for the 'VMNAME ' virtual machine. Refer to the Windows Event Log on the Hyper-V host for more details.
Backup Exec cannot remove the 'C:\VirtualMachines\VMNAME\RCT_Backup_VMNAME ' directory. Delete the directory from the Hyper-V server manually.
Beremote debug log on the Hyper-V host server will report the following error:

This issue occurs if the Virtual Machine name has a SPACE character in the name of the virtual machine name. As seen in the above log snippet there is a trailing SPACE character at the end of RCT file path of this virtual machine. This space character is added to the path from the Virtual Machine name defined in Hyper-V. The same Beremote debug log will show this space when getting the Virtual Machine name.
