Abstract

A data storage method and system of the portable terminal for storing data efficiently through a synchronization service are provided. The data storage method of a portable terminal includes determining whether a residual storage space of a data storage region of the portable terminal is equal to or less than a predetermined threshold value, performing, when the residual storage space is equal to or less than the threshold value, a packet data protocol context activation procedure, determining whether a new data save command is detected, storing, when the new data save command is detected, the new data in the residual storage space, and increasing the residual storage space to be equal to or greater than the threshold value by at least one of deleting synchronization-complete data among synchronization-enabled data stored in the portable terminal and transferring synchronization-incomplete data to a predetermined synchronization service server.
