Abstract
An information center backs up the vehicle-use data of an on-vehicle terminal apparatus. The vehicle-use data used by the on-vehicle terminal apparatus is classified into standard data or custom data. The standard data is used in the same manner by numerous vehicles, while custom data is unique to each vehicle. The custom data is sent unchanged to the information center but, for the standard data, identification codes are sent rather than the raw standard data. This data is backed up and stored in the information center, where they remain available for retrieval should the data on the vehicle side be damaged. Because the volume of backup data is reduced, the communication time can be shortened and the required backup memory capacity in the information center can be reduced.
