Abstract:
An example of an information processing system includes first storage means for storing saved data of an application and a second storage means. The information processing system, every time saved data is updated, stores, in the first storage means and the second storage means, identification information indicating the updated saved data. Further, the information processing system, every time saved data is updated, stores, in at least one of the first storage means and the second storage means, the identification information corresponding to the saved data before being updated. Use of the saved data stored in the first storage means is allowed at least under the condition that the identification information indicating the same saved data is stored in the first storage means and the second storage means.
