Take a look to the FGDataBackup on
http://www.versiontracker.com/dyn/moreinfo/macosx/29322
It's a complete backup data from disk folders to CD or DVD media. The software calculate the total size of the selected folders and span data on different media as necessary for complete the backup.
Kind regards.
I developed, time ago, a little utility for save good preferences and restore it, when need.
The name is FGPreferecesManager.
