Is there any free app out there that can do spanning backups? I got files that will cover more than one DVD. I know I can use a hard drive and use Carbon Copy Cloner to do a make a safe and bootable backup of my whole drive. However, I was wondering if there was a way to say burn a copy of my home folder across a few DVD's. I know of Toast and .Mac's Backup can do that. Anything out there that's free?
