Lan-Free Backup With BE 2012

Hello every one

I have question regarding Backup Exec 2012 Lan-Free Backup.

I got  6 ESX Host , all of my VM's are on EMC SAN and connected by FC to my ESX Hosts.

• What licenses (Agent & Option) I need to backup my servers using FC Network?
• What type of storage i can Use for my Backup exec server(Backup Storage)? can it be on another SAN Storage?
• After backing up my servers using Lan-Free Solution can i do Granular Recovery's? (Exchange -AD -SQL...)
• Can i Use only ADBO Option to do a lan-free backup?

Thank you guys
