I have the same problem as emgh3 with my ReadyNas+ NAS storage device. I am using Windows XP SP 2 and the same version of Retrospect Professional. When I use duplicate, every single file copied from the host PC to the REadyNas+ receives an error for "different creation time/date". When these same files are included in a normal or reycle backup; none of these files display the error. This is very disconcerting. I just copied 654 .tif files to the ReadyNas+ and received 654 warnings. Anything I can do to stop the warnings and fix this matter?
