Backup Exec V-Ray Edition

Hi,

We plan to purchase BE2014 V-Ray Edition for the following working Environment:

      2 Clustered Hyper-V Host with 2 Processors having 8 cores each

      Each host has 3 Virtual Machines:

           File Server using 4 cores

           Management using 2 cores

           AD using 2 cores

We would like to back the images of the virtual machines and the files and folders in the File Server Virtual Machine

Appreciate if you enlighten as to how many licenses should we need to pruchase;

Thanks,

PTU
