Backup Exec 2012 - How to license B2D-Capacity

Hi,

am new to BUE and have the following question:

I am used to implement staging capacities with other vendor backup

software products. How does this work with BUE 2012?

Do i have to buy a special option like Advanced Backup to disk or something else?

Do i have to buy Capacity? What do i have to consider

when using Backup Exec as v-Ray-Edition?

Thanks in advance for your replies.

Best regards

Lucas
