I've been using Iomega Backup Software version 1.0 with my Windows XP and will be upgrading to a Windows 10 computer. I've tested the 1.0 version on Windows 10 and it will not work. This is a great backup program because it will automatically sense which files have been modified and instantly back them up. I have not been able to find any other backup program that will do this. I see that an Iomega 3.3 version was made but I cannot find a legitimate download for it anywhere. First, would this version work with Windows 10, and second, if so, is there a place to obtain a copy? If not, does anyone know of any other backup program that would automatically run in the background, sense when a file was modified, and instantly back that file up? It doesn't have to be a free program. Any help you can give me would be greatly appreciated.
