Backing up a deduped file system

Here is the set up.

Windows server 2008 RC with a 8Tbye FC mapped LUN.

VSphere set up with a hosts datastore mapped to an NFS share on the above windows server.

a VMware DR appliance with a VMDK on the above NFS datastore.

So the VDR appliance is backing up to the VMDK which is on the LUN on the 2008 server...

that all works fine, until I go to backup the data on the windows server. I can't back up the LUN from the SAN server as its to dumb to allow that. So I have to back up the disk on the windows server that contains the VMDK, but of course when I do this using the wndows back up tool, it un-dedupes the data and then re-dedupes it making for a very slow back up.

So the question is, there a simple block level back up tool or other method to copy the VMDK files from the windows server in there native form so avoiding issues with any dudupe?
