Abstract: A PC performs full synchronization with a cloud system, whereas a smart phone performs thumbnail synchronization with the cloud system. Furthermore, when uploading a photograph to the cloud system, the PC and the smart phone create a thumbnail “medium” from the original photograph and send the thumbnail “medium” to the cloud system together with the original photograph. Furthermore, when creating the thumbnail “medium” and when one side is excessively longer than the other side, the PC and the smart phone reduce the long side to a predetermined threshold while maintaining the aspect ratio.

Abstract: An information processing terminal includes a processor configured to execute a process. The process includes sharing, first storing, second storing, acquiring, and synchronizing. The sharing includes sharing a storage device with other information processing terminals in an information processing system that synchronizes data among the storage device and all of the information processing terminals. The first storing includes storing data and update information indicating whether the data is updated after synchronization. The second storing includes storing a latest date and time at which the data stored and data stored in the storage device are synchronized. The acquiring includes acquiring a latest date and time at which the storage device is synchronized with any of the information processing terminals when synchronizing data. The synchronizing includes synchronizing, when the latest date and time acquired and the latest date and time stored match each other, with the storage device, the data.
