Carbon Backup....Just maybe a decent backup tool
Seems like ROM Manager has created a new backup tool called Carbon which will be able to backup across different Android devices. It is still beta, and requires root, but looks promising. Check out the link from AndroidCentral.
Better write up in AndroidPolice here http://www.androidpolice.com/2013/01/14/koushs-latest-app-is-carbon-not-that-carbon-a-free-app-backup-solution-for-google-drive-and-more/
Hopefully this doesn't just turn into vapor ware like the last Carbon named app we heard of....
