Embodiment Construction

[0091] The secure network storage system CorsBox based on personal user sharing is mainly composed of client software, server software and cloud storage service platform. The data synchronization method based on the directory tree runs in the CorsBox system.

[0092] In the CorsBox system, the server and cloud storage are connected through an Ethernet switch, and the client and server are connected through the Internet. The directory tree stored on the client is called the client directory tree, the directory tree stored on the server is called the server-side directory tree, and the directory tree constructed by scanning the disk in real time when the client needs to use it is called the disk directory tree.

[0093]When the client needs to synchronize, it first sends a synchronization request to the server, and the server returns its server-side directory tree after verifying the user's identity.

[0094] The server-side directory tree is stored on the server side, and is us...

Abstract

The invention discloses a data synchronization method based on a directory tree in a safe network disc system, belongs to the field of multi-machine synchronization and particularly relates to the field of file synchronization. The method is characterized in that a client is required to store only one client directory tree to complete synchronization, the storage efficiency is improved, a server can know the real-time situation of cloud data according to the directory tree, the system overhead is reduced, two-time directory tree comparison and one-time result comparison are merely performed during the process of generating the synchronization operation, the data synchronization efficiency is improved, the entire data synchronization process is unrelated to content of data, the data security during the synchronization process is guaranteed, and thereby the method can be applied to any network disc system which is provided with a security mechanism.

Description

technical field [0001] A data synchronization method based on a directory tree belongs to the field of multi-machine synchronization, and particularly relates to the field of file synchronization. Background technique [0002] Data synchronization refers to the backup operation of the same data between different storage devices or terminals and servers, terminals and terminals. Currently, the SyncML protocol and the Rsync method are the most commonly used data synchronization methods in the network disk system. SyncML is a platform-independent information synchronization standard protocol, which is based on a platform-independent XML language, and can perform an open, industry-wide standard remote data and personal information synchronization among several networks, platforms and devices. The Rsync method is a synchronization method for incremental uploads, and the synchronization operation is performed by comparing the hash value of the file block as a judgment basis. How...
