I recently switched from QB Enterprise 2012 to QB Premier 2019.  Data files were converted and the new installation is working fine.  I set up the backup routine to the same way it was set up in the old Enterprise product.  The backup is set to run nightly, saving the backup to the E drive which is a separate drive attached to my computer via a USB connection.  This drive has plenty of free space and the process worked flawlessly under Enterprise.   When I run the backup manually for the Premier product, the backup works fine.  However when it runs automatically overnight, I only get a very small TMP file.  I have stored my Windows password as required.  Any help would be greatly appreciated.  Thank you.
