DPM Pricing

I am trying to figure out if I should purchase DPM which I do prefer as I have extensive experience using the product at previous companies I worked for however the licensing always confuses me. If too expensive I will possibly be looking at Hyperoo or Altaro instead.

If I have 1 server to be backed up with say 8 VMs on it.

Hence 1 backup server

and 1 Server with 8 VMs on it.

How much will this cost me? The CPU being used in a Intel Xeon E3-1230 Quad Core 3.2GHz
