Let us turn now to the other Carbon app for Android (no, not that one -- this one), which today has seen its second beta release. This Carbon serves as a way to back up your app and, perhaps more important your app data, and move both between devices.
This second beta brings Dropbox support, gives more control over what you can back up (more apps at once, or all apps), and you can choose to backup everything at once, if you want. This one's still a root-only thing, but Koush says that should change with the third and final beta release.
