SYSTEM AND METHOD FOR SYNCHRONIZING DISTRIBUTED STORED DOCUMENTS

A system for synchronizing distributed stored documents includes a core-node (110), a plurality of branch-nodes (120, 130), and a network (140) connecting the core-node with the branch-nodes. Each branch-node includes: a branch-database server (123, 133) for storing a summary of all distributed stored documents, wherein the summary can be updated in accordance with a sync message received from the core-node; and a branch-FTP (File Transfer Protocol) server for storing the distributed stored documents, the branch-FTP server having the function of exchanging documents with the core-node. The core-node includes a core-database server (113), a core-FTP server (309), and an application server (310). The core-database server stores a summary of all distributed stored documents. The core-FTP server is used for storing the distributed stored documents. The application server comprises a sync controlling module (313) that controls data exchange between the core-FTP server and the branch-FTP servers. A related method is also disclosed.
