I got tired of the kludgey batch files and windows scheduling issues or even trying to figure out windows backup or some over-the-top program that does everything. I end up downloading this tiny app to back up my work files to another drive. I can quickly check it to see the status of the copy, when the next one will occur and it creates a log. It is dead simple, uses 3MB memory and never complains even if the files are open. In fact I have never even noticed it working.
