Consider the following scenario:
Note If you use System Center Data Protection Manager 2007 to back up the virtual machine files, you may receive the following error message:
One or more volumes are missing for the following applications:
Backup Using Child Partition Shapshot\vmname (ID:3504)
Ensure that the dependant volumes for the data sources are online.
This problem occurs because the file path is misreported in the writer metadata that is sent to the backup applications by the Hyper-V Management service (Vmms.exe). Therefore, backup applications cannot recognize the volume, and the backup operations fail.
