Cloud storage system and method, user terminal and cloud storage server

Abstract

The invention discloses a cloud storage system comprising a user terminal and a cloud storage server. The user terminal generates a service request, extracts a data characteristic code and a data type, and packages the data characteristic code, the data type and the service request and then transmits the data characteristic code, the data type and the service request to the cloud storage server. The cloud storage server divides an overall abstract dictionary into characteristic code dictionaries with different data types, receives and analyzes the data characteristic code, the data type and the service request and processes the service request according to the data type. The invention also discloses a cloud storage method, the user terminal and the cloud storage server, and another type of a cloud storage system method, a user terminal and a cloud storage server. With application of the invention, calculation burden of the cloud storage server is reduced and retrieval efficiency is enhanced.

Description

Technical field [0001] The present invention relates to the technical field of cloud storage, in particular to a cloud storage system, a method, a user terminal and a cloud storage server. Background technique [0002] Cloud storage refers to a system that integrates various types of storage devices in the network through application software through functions such as cluster applications, grid technology or distributed file systems to work together to provide data storage and business access functions to the outside world. The structure of the existing online cloud storage system is as follows figure 1 As shown, it consists of two parts: the user side and the cloud storage server; among them, the user side is used to send business requests such as uploading data, deleting data, and sharing data; the communication module is used to transmit and parse data and business requests; the cloud storage server is used to Receiving and processing the service request, the user management m...

AI Technical Summary

Problems solved by technology

At present, there is such a situation that part of data A1 in data A exists in the cloud storage server before data A is uploaded to the cloud storage server, and another part of data A2 in data A is uploaded to the cloud storage server after data A Before, it did not exist in the cloud storage server; in this way, after data A is uploaded to the cloud storage server, the cloud storage server will store data A1 repeatedly, resulting in a waste of storage resources

Especially in the process of data update or data synchronization between the client and the cloud storage server, the repeated upload of data increases the transmission bandwidth, which may easily cause the communication speed between the client and the cloud storage server to slow down
