Just wondering if there was ever a resolution to this?  I have QuickBooks Desktop Pro 2019 and recently upgraded to a new computer with Windows 10 and my automatic (local) backups are not working.  I have tried deleting the scheduled backup and creating a new one, double checking the backup location (manual backups work), uninstalling and reinstalling QuickBooks and also checking the compatibility mode.  When I try to change the compatibility mode, it doesn't give me an option for Windows 10 - Windows 8 is the latest version it shows.  I even called QuickBooks support and they told me I would have to pay for premium support or figure it out myself.  So here I am.  Any suggestions would be greatly appreciated.
