Problems solved by technology

And when node C only accesses the file after node B updates the file, then the first synchronization is redundant
[0005] Second, in some cases, the amount of network traffic for synchronous operations is too large
For example, a file is required by all nodes in the network. After the file is updated, it needs to be synchronized with all network nodes at the same time. The sudden data transmission is too large.

Embodiment Construction

[0022] refer to figure 1 As shown, it is a schematic diagram of the implementation environment of the multi-node file synchronization system and method of the present invention. The system includes multiple slave nodes 100A, B, C, a network 110 and a master node 120 . Each slave node 100A, B, C includes a slave application server 101 , an agent program 102 , a slave file server 103 and a slave database 104 . The master node 120 includes a master application server 121 , a synchronization program 122 , a master file server 123 and a master database 124 .

[0023] Among them, the slave nodes 100A, B, and C refer to network nodes acting as servers in corresponding subnetworks (not shown), these subnetworks also include multiple clients (not shown), and interconnect devices through multiple networks Access network 110. These client running programs send file operation requests to the slave nodes 100A, B, and C. In the description of this preferred embodiment, each slave node 1...

Abstract

The system comprises a master node, multiple slave nodes, and network connecting the master node to these slave nodes. The slave node comprises a slave application server, a slave file server and a slave database. The master node comprises a master application server, a master file server and a master database. Based on file updated record in the master database, running an agent program on a slave application server and running a synchronous program on the master application server complete synchronization between files in the master file server and files in slave file server. The system and method realizes synchronization of files shared between master node and slave nodes on network, as well as reduces unnecessary file synchronization operation and prevents the condition of too large networked traffic needed by some synchronization operations.

Description

【Technical field】 [0001] The invention relates to a file synchronization system and method, in particular to a system and method capable of realizing file synchronization between server nodes in a network. 【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 in various places, and the branches in various places need to share information for joint operations. Therefore, how to manage its data to realize the sharing of enterprise resources has become an important part of the operation of this type of enterprise. With the development of network communication technology, cross-regional data access and collaborative editing become possible. For this reason, enterprises generally adopt distributed file management systems. [0003] A distributed file management system is a file management system that is phy...
