Backing up VHD's with Backup Exec 12.5

Hi,
I have just run up a Hyper-v on a box and have one VM on it running Server 2008. I have another server that has Backup Exec 12.5 for Windows Servers on it. I have installed the Windows remote agent on the Hyper-v box.
I am trying to backup the folder on the Hyper-v box that contains the VHD files for the VM. The backup job runs and completes successfully but the VHD's are not backed up. Should I be able to do this with Backup Exec or do I require the "Backup Exec Agent for Microsoft Virtual Servers"

When Backup Exec detects Microsoft Virtual Server on a computer, it creates a Microsoft Virtual Server container. The container appears under User Data, which appears under Shadow Copy Components in the backup selections list. The Microsoft Virtual Server container includes each guest virtual machine that resides on the virtual server, which is also called the host. It also contains the Virtual Server Configuration. You can back up the entire host, individual guest machines, or the Virtual Server Configuration.

Virtual Server Configuration contains the Virtual Server configuration settings and virtual networks. You should always have a current backup of the Virtual Server Configuration. Back up the Virtual Server Configuration whenever you make changes to configuration files.

Backup Exec uses Microsofts Volume Shadow Copy Service (VSS) to back up Virtual Server data. Backup Exec takes a snapshot of the Virtual Server Host while applications and services are still running. The host in turn takes snapshots of all the guest virtual machines it contains.

Only the guest virtual machines that run Microsoft Windows Server 2003 or later with virtual machine additions installed are available for backups without downtime. Any other guest virtual machines are briefly placed in a saved state for backups. The amount of downtime that is required depends on your computers resources.

When you select a guest virtual machine for backup, the backup is a full image of the entire guest virtual machine.

The backup includes the following components:

Differencing virtual hard disk

Undo virtual hard disk

.vhd files

.vmc files

.vsv files

If the parent differencing disk is modified after it is backed up, the related child disks do not work. To ensure an accurate restore, the parent differencing disk should be locked so that it cannot be modified after it is backed up.

Backup Exec can back up only the files that reside on the virtual server. Virtual machines that have iSCSI or remote .vhd files are excluded from backup jobs.
