Distributed file synchronization system and method

Abstract

The invention relates to a distributed file synchronization system and method. The distributed file synchronization system comprises a master node used for storing synchronous files, scanning all synchronous files thereof according to a fixed time, generating meta information of the synchronous files and sending the meta information to a database server; slave nodes, used for downloading the synchronous files from the master node and storing the synchronous files; and the database server, used for receiving the meta information sent by the master node, separately matching the meta information sent by the master node with the meta information of the slave nodes stored in local, driving the corresponding slave node to download the synchronous file corresponding to the meta information sent by the master node from the master node in the case of a matching failure and adding the meta information sent by the master node in a local storage space of the meta information of the corresponding slave node. By adopting the distributed file synchronization system and method provided by the invention, automatic synchronization of the synchronous files issued by the master node on the slave nodes, namely the automatic synchronization of distributed files, is achieved effectively, and the defects of troublesome work and error proneness of manual synchronization are avoided.

Description

technical field [0001] The invention relates to the technical field of computer network processing, in particular to a distributed file synchronization system and method. Background technique [0002] Nowadays, with the increase of user demands from all walks of life and the increase in the number of users, traditional single-node applications cannot meet the increasing user demands, so distributed came into being, and now distributed has become a familiar concept , distributed can linearly improve the overall performance of the application as the number of distributed nodes increases, but distributed also brings us a lot of troubles, such as full synchronization and differentiated synchronization on different distributed nodes, so that application publishers can One is to synchronize each synchronization file to all distributed nodes, and to ensure the differential synchronization of some differentiated files, which makes the work of the publisher very cumbersome and error-...
