Security DVR work-around? (Symlink Question)

Greetings,

I have a q-see PC based DVR that came with some pretty terrible software. I'd like to be able to write data to my local hard-disk and to my network share at the same time. I've got plenty of network bandwidth available to do this, and plenty of storage on the network also. The reason I want to do this is that my NFS is stored in the building behind my house (which is my computer shop) and I am worried that someone may break into my house and steal my DVR with all of the evidence of their break in. The software doesn't allow these shenanigans at all, so I need to come up with some kind of work-around that is live and in real time. Any suggestions?
