Smartware won't backup Outlook files if the file size is unchanged

My Outlook files haven’t been backed up for a week so I ran a backup and again they were not backed. I noticed that the file size in the backup was the same as the original on disk (file dates were different) so I compacted my outlook file ran another backup. This time the new outlook file was copied to the My Cloud drive.

Hello, how do you have your backup schedule working?
