Network computer system and method for executing data synchronization process thereof

Claim 1

A network computer system, comprising: a server computer; a plurality of network computers; at least one network for coupling between the server computer and the plurality of network computers, wherein the server computer stores original resources having data including at least an OS and a synchronization list for identifying synchronous objects for synchronization of the original resources to each one of the plurality of network computers, the OS includes a synchronization process for the synchronization of the original resources, and wherein each of the plurality of the network computers includes a local storage for storing downloaded replicas of the original resources from the server computer to the network computer and a downloaded replica list of the synchronization list of the server computer for identifying synchronous objects for executing the synchronization, the synchronization list includes optional information for determining execution of the synchronization between the server computer and the local storage, and the local storage is used to store the replicas of the resources stored in the server computer and the replica list of the synchronization list stored in the server computer; means for operating the each of the plurality of network computers by using resource replicas stored in the local storage without accessing to the server computer; means for comparing the synchronization list in the server computer and the replica list in the local storage at a synchronization stage in an on-line connection to the server computer; and means for executing the synchronization between the resources in the server computer and the resource replicas in the each of the plurality of network computers using a result of a comparison by the comparing means.
