Solve : .bat to make backups without overwrite larger file?

1.	Solve : .bat to make backups without overwrite larger file?
Answer» I tired to fit as much as possible into the topic. I know how to SIMPLY COPY stuff from one dir to ANOTHER. How would i copy stuff from one dir to the other with out over writting the larger file? I need to backup txt files every HOUR, but sometimes the origional txt files get messed up (why i need backups), then it copys over the messed up files and BLAM backups are pointless. So Please help my write a batch file that will copy files as long as they are larger in file size.This may take a utility that's a bit more complex than a batch file. Most backups are keyed on the age of the file, not the size. I suspect you could do this with AutoIt HTTP://www.autoitscript.com/autoit3/ without too much trouble...
