Abstract

The invention provides an intelligent user operation discovery method of a file system, which comprises the steps of: using a node mark of the file system as a unique mark, and comparing a node of a local synchronous catalogue with the file system node when the former synchronization operation is successful so as to identify user operation behaviors. In particular, the method in the invention comprises the steps of: using the node mark ino number of the file system as the unique mark, comparing the ino number with the change of paths and contents of the corresponding nodes to identify such user operations as newly adding, deleting, renaming, moving and file content amending, and the like. The method of comparing by the node mark of the file system is combined with a traditional directory tree comparison method to discover the user operation behaviors. The file synchronous system of the invention is used for reducing the synchronous operation quantity and reducing the dissipation of network flow.

Description

technical field

[0001] The invention relates to a user operation discovery method of a file system and a synchronization system applying the method, belonging to the technical field of computer networks. Background technique

[0002] With the development of the Internet, more and more user data is put on the Internet. Network storage is booming, forming a very good complementary relationship with traditional local hard disk storage. In this state, how to synchronize the user's local data to multiple devices has become a topic of concern to many users.

[0003] Synchronous network storage such as qbox.me is a typical synchronization software, which allows users to automatically synchronize data on PCs (including Windows / MacOS / Linux platforms) with the Web and mobile phones without any user intervention. Even if the user closes the synchronization software, if the user performs a series of operations on the directory to be synchronized, after the synchronization software is ...

Examples

Embodiment Construction

[0046] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0047] First, let's introduce the background knowledge. Generally speaking, the file system is the place where users store data. Although they are all physically hard disks, there are actually many forms of file systems. The file system organizes information in a tree form, which can be called "directory" or "folder" with sub-nodes (collectively referred to as "directory" in this article); the storage of data content is called "file". Both directories and files are "nodes" in the file system. Under Windows, the two most popular file systems are NTFS and FAT32; under Linux, it is the EXT3 file system.

[0048] According to the characteristics of the file system, the file system can be divided into two categories:

[0049] One category is that the "node" of the file system itself has a unique identifier; for example, the NTFS and EXT3 file sys...
