BackupExec 2012 License for Applications and Database

Hi,

I got two (2) servers running the following:

Server 1 Windows 2012 DataCenter with four VMs

- VM 1 = runs Exchange

- VM 2 = runs Exchange

- VM 3 = SQL

- VM 4 = AD

Server 2 Windows 2012 STD

- Active Directory

Question:

1. How many license for Backup Exec Agent for Applications and Databases do I need for my First Server?

              ---> Do I still need purchase a  license for Backup agent for windows and how many?

2. Are there are other licenses required to restore Virtual Machine OSE to a Physical OSE on different hardware ?  

              ---> Virtual to Physical conversion.

3. For my second server, I understand a license for Backup Exec Agent for Applications and Databases si required to backup my AD.

             ---> Do I need a backup agent for windows to allow me to do a full system backup (image backup) and  baremetal restore ?

Thanks,

Paul
