Problems solved by technology

[0003] At present, the cloud storage system allocates storage nodes by taking modulus or hashing and re-hashing, which can realize the complex balance of servers, but each block storage node needs the main server to perform calculation and redistribution, which will greatly increase the Increased the CPU load of the main server and reduced the efficiency of the system
The traditional backup method is to assign each sub-block to a node, and the node sends this sub-block to all other nodes, which significantly increases the load on the server and leads to the existence of a large amount of redundant data

Abstract

The invention discloses a cloud storage data backup method based on characteristic codes. The cloud storage data backup method based on the characteristic codes comprises the steps of monitoring available storage nodes of each storage area by sending a request of uploading a file, generating a index table and carrying out feedback, segmenting the file and obtaining a plurality of file blocks, carrying characteristic code distribution of the plurality of file blocks, carrying out characteristic code distribution of storage nodes in a corresponding storage area and storage nodes of a backup storage area, uploading the file to the nodes of the corresponding storage area and the nodes of the backup storage area, and carrying out storing. According to the cloud storage data backup method based on the characteristic codes, different storage areas are used for the backup, each backup is stored in different storage areas, and then reliability of cloud storage data is improved, time for finding the storage nodes is effectively saved with a characteristic code method, system efficiency is improved and load of a server is reduced. The cloud storage data backup method based on the characteristic codes is applied to cloud storage systems.

Description

technical field [0001] The invention relates to the field of cloud storage, in particular to a feature code-based cloud storage data backup method. Background technique [0002] With the continuous development of computer technology and the continuous improvement of informatization, people's dependence on information is getting higher and higher. The highly centralized storage of information in the IT environment greatly improves the automation of information and data management, improves operational efficiency, and reduces costs. Cloud storage is a new concept extended and developed from the concept of cloud computing. It refers to the collection of a large number of different types of storage devices in the network through application software through functions such as cluster applications, grid technology, or distributed file systems. A system that works together to provide data storage and business access functions to the outside world. When the core of cloud computing...
