Howto export Tapes from Library via Backup Exec 2012

Hi there,

i got a problem.

I want to export circa 35 Tapes from my robotic Library (Quantum i500) to the export slots.

How can i do this with Backup Exec 2012?

I have already moved the Media to a Mediavault which is called "Off-Site Fullbackup"

I have associated the Media with a Mediaset.

But i can not tell BE 2012 to export all those tapes which are located in the MediaVault.

Thanks for you answers.

Cheers,

Sebastian
