Back Up Exec solution for 3 Servers

Hello all,
My client is requiring a new apps server, a new exchange server and has an existing Terminal server. We put forward a solution for backing it all up to a NAS box and aske our reseller the best way to do it.
We have discussed with them and they have suggested we run the Backup exec on the apps server, with an exchange agent for the exchange server and an agent for the terminal server and active directory back up agent. We have also taken 2 System recovery licenses to.
These are exactly what we have been quoted on.
