Embodiment Construction

[0014] Such as figure 1 Shown is an implementation environment diagram of the distributed file synchronization system and method of the present invention. The system is composed of enterprise information system nodes scattered in different geographical locations, which specifically includes a master node 110 and several branch nodes 120, 130 (only two are shown in the figure). These nodes are connected by intranet 140, and all adopt three-layer (or multi-layer) structure: a database server (113, 123 or 133), a series of application servers (112, 122 or 132), and scattered clients (111, 121 or 131). The composition of each node will be introduced below by taking the master node 110 as an example.

[0015] The master node 110 includes a database server 113, an application server system 112 and several clients 111 (only one is shown in the figure). The database server 113 is used to store all data related to the enterprise, and is responsible for managing the reading, writing ...

Abstract

The system includes a main node, several branch nodes and network connecting the main node with the said branch nodes. The main node is a center for controlling synchronization operation. The main server includes a main data server, a main FTP server and an application program server. A synchronization control module in the application program server is utilized to control data transmission between main FTP server and branch FTP server in branch node, as well as to update file digest information of database server in main node. Branch node in the system includes at least one branch database server and a branch FTP server. Running synchronization program in application program server at main server makes file synchronization operation separate from branch node so as to expand branch node easily.

Description

【Technical field】 [0001] The invention relates to a file synchronization system and method, in particular to a distributed file synchronization system and method. 【Background technique】 [0002] With the development trend of economic globalization, a large number of large enterprise groups that cross regions and borders have emerged. The branches of these enterprise groups are distributed all over the world, and the branches need to share information to work together. Therefore, how to manage and control its data to realize the sharing of enterprise information resources has become an important part of the operation of this type of enterprise. The development of information technology has made cross-institutional and cross-regional data access and collaboration possible. At present, in order to improve the efficiency of data access and reduce the loss of failures, enterprises generally use distributed data management systems. [0003] A distributed data management system ...
