Deduplication. Windows Server 2012 r2 & Backup Exec 2014

Hi, I've just installed Backup Exec 2014 on Windows Server 2012 R2.

Upon configuring storage my plan was to create a deduplication volume to use as my main backup target.

However, this appears to not be an option and the textbox suggests using Windows to control Dedupe. (I can add the role easily enough)

My quesion is : Is this correct or have I missed something?

My other backup exec server is windows 2008 and backup exec 2014. On that server has the option to create the Disk folder as a deduplication store.

Thanks.
