I have the same problem. After I installed Windows 10 Professional and DBAR 1.9.0.22 Premium I'm not able to create a Windows 10 system backup. After approx. 1 hour I get the error message 'A system error has occurred'.
I have run a disk check of the backup disc and it reported that the disc is OK, I have tried to reboot, uninstall and reinstall DBAR 1.9.0.22. It did not help.
What can I do to make a system backup of Windows 10?
