restoring mailbox in exchange 2010 using DPM 2010

I'm restoring a single mailbox using DPM 2010 to a restor DP

I first created the RDB with

new-mailboxdatabase -Recovery -Name MBrestore -Server servername -EdbFilePath "f:\Mailbox\MBrestore\mbrestore.edb" -LogFolderPath "f:\Logs\mbrestore\"

In DPM I pointed to this DB

The mailbox is 250 megs, so far DPM has restored 179GB (the full  .EBD file is 713GB).

Anyone know why this is so large? What do I do now to get it to a PST file so the user can scan through it to find out what they are is missing?

cheers Mark

When I am doing this in our enviroment  it is like this:
I have to restore full mailbox database.
Then mail admin maps recovered users mailbox to user current mailbox - folder Recovery or something simmilar.
User moves lost mails from Recovery folder to current mailbox and deletes folder Recovery.

Thanks, it does seem to create a giant DB which blew out my host last night. I'm doing this again on a host with enough room. Once this has finished does anyone know how to create a pst out of this afterwards?
