Backup Exec 12.5 Rev 2213
Exchange 2007 SP1

Full Backup of new Exchange server shows as successful, and displays the right amount of data as having been backed up for the Information Store. However, when trying to expand the backup to test restores, I see the red icon indicating "Backup log contains corrupt data" and it will not expand to show me the mailboxes or items within the store.

Has anyone come across this before and know the fix?
