Exchange 2010 individual mailbox from .edb

I'm trying to restore an Exchange 2010 mailbox using BackUp Exec 2010 R3.  When I view the media, I see just the database.edb, along with a subfolder containing CMP Files, DELTA Files, ARRAY Files, BLKS Files, VIEW Files.  I thought I was suppose to be able to see the individual mailboxes.  From the looks of it, the person who configured the backups didn't include the Information Store selection, is this correct?  Am I able to restore a single mailbox from this backup, or do I need to restore the entire database to get what I need?
