VCB with VMFX and RDM disks

We are currently looking at implementing VCB, and we have some machines with RDM Disks. These disks have been connected in physical mode because of SAN implications, but the OS is all installed on VMFX disks (C$). The RDM's are just data. I know that VCB can't back up RDM Physical disks, but can we use VCM to back up the C$'s so that we can restore the server and reconnect the RDM's if we need to? We will use a separate back up utility to back up the data. I've looked at the docs and can't say anywhere where it talks about this. I May of course be being dim - please tell me if I am!
