I just looked at the output of a scheduled backup task of type Email in v11. It was only 75k, even though the Outlook files being backed up were in excess of 100MB. I had this problem in v10 as well. Looks like a bug to me; anyone else have a similar problem? On a more positive note, an email backup with the exact same configuration that was run immediately instead of being run as a scheduled task worked as expected. Could there be something wrong with the 'Schedule a backup task' wizard, or whatever you call it?
