File data synchronizer in a distributed data computer network

摘要

In a computer network comprised of multiple nodes spread across different geographic locations and connected through a communication system, a Distributed Data Synchronizer (DDS) synchronizes files across the network so that user applications running at the various nodes can share common databases of information. In a preferred embodiment, rather than store master files at a server node, each node stores a master copy locally in a disk drive. When a user application modifies one of the local files, the DDS communicates the update to the appropriate remote nodes under the control of a user defined script file.
