MBL backup to CrashPlan Pro

Hello,  I have a lot of very important data stored on My Book Live that I would like to have automatically backup (as my computer does) to my CrashPlan Pro account.

The problem is that while I can see the MBL loaded in Finder on my MacBook Pro, it comes up under Shared and not Places so I cannot navigate to it with CrashPlan to establish a backup.

Any suggestions on how to resolve this issue or how to create another automatic backup from the MBL?

Thanks!

Maybe that application is not designed to backup a network location
