Is there any way to take these backup fragments from my second to last backup and turn them into a usable backup? iTunes is showing me only the most recent.

Ok. When I synced today at 5:10PM, it backed up. Somehow, that sync deleted Garageband and all it's data (like the song I've been working on for a month), presumably because it was updated today. Before I realized this, I had synced again (10:02 pm). So iTunes only shows me THAT backup. I can see a bunch of files from the 5:10 backup. Apple told me that you, Obi-wan, the community, are pretty much my only hope. Have one of you guys (or gals) figured out how to do this?

Turn the quarks of a backup into the atoms of a backup?
