Abstract:
A data synchronization device for performing synchronization of data between devices retaining data, said data synchronization device having a synchronization process unit for comparing a first set of data retained in a first device with a second set of data retained in a second device and generating synchronized data;a first access unit sequentially updating the first set of data based on the synchronized data each time a synchronized data is generated, and releasing the first device from the synchronization process when updating of the first set of data based on all the synchronized data is complete; wherein the first device and the second device are connected via a network; the first access unit disconnects a connection of a network in the first device after the updating of the first set of data based on all the synchronized data is complete; wherein the second access unit records obstructed information in an obstructed information storage unit when an obstruction has occurred while updating the second set of data; and the second set of data is updated based on the obstructed information when other synchronization processes are performed in advance of these other synchronization processes.
