When you are in the process of acquiring an iOS device, your tool may give you a clue as to what you will be dealing with when parsing the data. Here we can see that UFED is prompting us to �Encrypt backup� for Beth�s iPhone. Your tool may only prompt you if iTunes has not already encrypted the backup. If you do not see this prompt in your tool (assuming you are using a tool like UFED), you will see a screen that states that iTunes backup encryption is already set on the device. Get ready to crack that password if this is the case.
