Disaster recovery cloud storage system construction method based on block chain technology

Abstract

The invention discloses a disaster recovery cloud storage system construction method based on a block chain technology. The block chain technology is introduced in a cloud storage system construction process. The characteristics of decentration and de-trust of the block chain technology are used to realize the distribution autonomy of storage nodes in a cloud storage system and data exchange and data sharing between the storage nodes based on a consensus algorithm. Compared with the current mainstream centralized cloud service system, the method has the advantages that network nodes can establish many-to-many rather than one-to-many contact relationship, which can greatly improve the transmission efficiency of data; and in the processes of data storage, exchange, upload and download, data block packaging and anonymous exchange and an asymmetric encryption algorithm are used, which greatly guarantees the safety and reliability of the entire ecological chain of data cloud storage. Compared with the current mainstream centralized cloud service system, the method provided by the invention has the advantages that on the basis of improved data safety, the operation efficiency of the system is greatly improved, and the operating cost of a cloud storage service is reduced.

Description

technical field [0001] The invention belongs to the technical field of cloud storage, and in particular relates to a construction method of a disaster recovery cloud storage system based on block chain technology. Background technique [0002] Cloud storage is an extension of the concept of cloud computing. Similar to cloud computing, cloud storage refers to the collection of a large number of different types of storage devices in the network through virtualization software to work together through cluster applications, grid technology or distributed file systems. Providing external data storage and business access functions is the management and use of virtualized storage resources. [0003] In recent years, many Internet companies have commercialized cloud storage services, such as Baidu Cloud Disk and 360 Cloud Disk, which are well-known in China. The currently widely used cloud storage system is a typical centralized system, that is, the corresponding Internet company b...

AI Technical Summary

Problems solved by technology

This centralized cloud storage service is easy to implement and promote, but it also has obvious disadvantages. The construction of its centralized platform requires a lot of manpower and material resources, and the operating cost is high. With the increase of cloud storage demand in the network center The modernization platform needs to be continuously expanded and strengthened to meet the speed requirements of data exchange and sharing

This centralized cloud storage system does not realize the essence of "cloud". A better cloud storage system should be decentralized, a data storage management system that can operate autonomously with a distributed autonomous mechanism
