Looking for a program that will span disks and copy data in native format

I know that there are a lot of programs that will allow you to backup your entire hard drive. The ones that I have seen so far compress or alter the files so that you have to use thate same software again to restore the files back to native format.
I would like to know if anyone has heard of a program stand alone or plug-in, that will allow you to backup directories to cd and will automatically span disks and not split individual files in the process. The most desirable program will allow you to:

  1. Backup directories
  2. Span disks automatically
  3. copy the files to cd in a readable format so that you can just go to any one of the disks and it will be readable

Is there anything out there like that?

Any and all help appreciated:confused:
