I would like to be able to efficiently backup, uncompressed, my mp3 collection across multiple discs. If it were just a once-and-done deal, I would do it manually with ImgBurn but, since I would want to update it as new files are added, I need something more efficient. WinRAR will span the discs but I do not know if it will do it without compressing the files. SyncBack Pro looks like it would work but that seems like gross overkill. There must be a simple solution that I am overlooking. Any suggestions?
