To restore, you can choose each, which partition you want to restore. Be careful with efs: these are device specific Data (Imei and other), do NOT (!!!) restore them on a different device, even if it is excactly the same model... restore efs only on the device where it came from... something like passeport for the individual device.. I have NEVER(!) restored efs partitition, if this is not nessesary, and that is very seldomly the case: I always backup this partition, but i never restore it! Be carefull and think before you do any action! ;-)
