SBS Backup File Sizes don't match?

I have a customer using the SBS Backup Wizrard to backup their server.  I am doing some verification of their disaster recovery plan, and noted that on the backup media, their priv1.edb file only takes up 7MB.  On Disk, it's about 8GB.  The backup method is "normal," and the backups all show "success."  Is NTBackup incorrectly reporting the size of the data on tape?  Has anyone else noticed a significant difference in file size on Tape vs size on disk of backup files, and .edb files in particular?

I strongly believe there is something wrong with the backup size, could you run ntbackup manually again & check this. Also ensure that you have correct selection of stores in place, expand Microsoft Exchange information store & ensure the Mailbox store & public fodler store is selected.

The information store is selected, and that's something else... when checking the size on Tape (NTBackup, restore, and checking the size of the component but NOT restoring) the Exchange Information Store has a size of 0KB...

I have attached the backup logs, and a screenshot of the Restore tab in NTBackup where I am concerned about the .edb file sizes.  On the manual backup tape I just made, it appears as though the file sizes look much better when going into the "Restore" tab.  The "Information Store" shows no files... is that normal?  

I will check it in the morning after another Automated run.

Everything is in fact getting backed up, NTBackup apparently just doesn't give the file size of the Information Store on the "Restore" tab in NTBackup.
