Titanium Backup is the most powerful backup tool on Android, and then
some. You can backup, restore, freeze (with Pro) your apps + data +
Market links. This includes all protected apps & system apps, plus
external data on your SD card. You can do 0-click batch & scheduled
backups. Backups will operate without closing any apps (with Pro). You
can move any app (or app data) to/from the SD card. You can browse any
app’s data and even query the Market to see detailed information about
the app. Needs ROOT, Android 1.5-5.0+ (ARM,x86,MIPS)
