HyperV Plugin: Working Directory not cleaned up after a backup job is aborted.
The plug-in does not currently clean up the Working Directory after a backup job is aborted. This prevents subsequent backups of the same machine and also prevents the mounting of other VMs. To work around this issue, you must manually delete the related files from the Working Directory.
This is a product defect. This will be fixed in a future version of HyperV plugin.
Manually delete the related files from the Working Directory.
