Question Please...

Is there such burning program that allows you to burn back-up data continuously and/or cut the data? When backing-up a file that's about 800MB on a 700MB CD-R, I want to continuously burn the extra 100MB on another disc, therefore, cutting the 800MB file (such as a movie file, or whatever the case maybe) to 700MB. Or another example, I'm trying to back-up a movie file, which is 705MB in size, into a 700MB disc, but I don't really need that last fifteen minutes or so of the movie so I don't care if it's cut (the extra 5MB). I don't really know if those are even possible, that's why I'm asking. I'm currently running Nero, but it doesn't let me go through when the file size exceeded the disc. Thanks!
