The backups occupy the entirety of your drive. You'll want to use "Smart Update", not "Copy Newer" -- and to recover, you'll typically start up from the backup, or copy the files back.

Please see the User's Guide for more -- Help > User's Guide. It goes into detail about how to work with all aspects of SuperDuper!

Note, too -- if you don't see anything on the FireWire drive, it could be a bug in Finder. Try Cmd-Option-Clicking its dock icon, and then choose "Relaunch". Then, check again.

Hope that helps!
