One easy and effective feature that Windows Movie Maker offers is the ability to backup Collections that you have made alterations on. If you have used effects on a clip or even deleted some sections, it is a good idea to save those changes, especially since video projects are so sensitive and can take a toll on your computer memory. If you accidentally remove critical media, or make non-reparable cuts on one of your clips, you can back track and save some of your lengthy editing work. Though it does not back up the original files you are using in the program, it will protect the editing project itself.
