The above statement is false. I got a new phone that never had my user data on it before. I restored = it from backup. The new phone had all my app data on it. It was only missing the device password (which needed to be set for the = new device anyway) and my TouchID hash because that is stored in the = processor and cannot be copied off the device. Ralf=E2=80=99s statement = above is demonstrably false. I understand the chafing at the closed system, but don=E2=80=99t make = false claims. Ralf is correct that iCloud backups do not contain the full app. They = instead contain the incremental diff between the current state of your = app with your app data and the original. This dramatically reduces the = bandwidth used in backup, just like many of us use rsync for the same = reason. Why would Apple send the whole app back to their servers when = they already have it? They can just send the diff like rsync does and = dramatically reduce the storage and bandwidth load.=
