Efficient and safe data cloud storage system implementation method and device

Abstract

The invention, which relates to the cloud storage field, provides a data cloud storage system that is composed of a plurality of servers and a plurality of data storage equipment. The method is characterized in that: an identity authentication mechanism and flexible operation authority setting are employed in cloud storage; each verification is carried out on data after each network transmission of the data; the network transmission is carried out after data compression; data in cloud are stored after encryption; backup is carried out on the data in cloud storage; the data that have been uploaded to the cloud storage can be updated only by uploading difference information; automatic load balancing is carried out to better utilize an idle processor and a network memory in cloud; both a user and an administrator can customize a strategy conveniently; and an administrator can monitor a serving state of the cloud storage. A cloud storage system that utilizes the technical scheme of the method enables security, integrity, availability of data storage and adaptive capability of the system to be improved; meanwhile, an operational efficiency and controllability of the system are also enhanced.

Description

technical field [0001] The invention relates to the field of cloud storage, that is, a network-based implementation method and device for an efficient and safe data cloud storage system composed of several servers and several network storage devices to ensure data security and efficient reading. Background technique [0002] Cloud storage is a new concept extended and developed on the concept of cloud computing. It refers to the integration of a large number of different types of storage devices in the network through functions such as cluster applications, grid technology or distributed file systems. A system that works together through a collection of application software to jointly provide data storage and business access functions. When the core of cloud computing system computing and processing is the storage and management of large amounts of data, a large number of storage devices need to be configured in the cloud computing system, then the cloud computing system wil...

Problems solved by technology

This greatly reduces the confidentiality of user data and cannot share information with other users;

[0006] 2. The network environment for providing services is too single, and some methods / systems even designate a unique type of storage server to store data (the publication number is CN 101605148A);

[0007] 3. After some content of the stored data is edited, all the data must be re-uploaded to overwrite the original stored data to update, and the unedited content of the data will also be uploaded, increasing the network overhead of the end user;

[0008] 4. The data stored in the cloud storage is not encrypted, the user data has no confidentiality at all, and the integrity and availability are reduced;

[0009] 5. There is no reasonable backup data (only the file is simply divided and saved in the corresponding server), and the integrity and availability of user data are reduced;

[0010] 6. Lack of monitoring and storage system;

[0011] 7. Lack of load balancing mechanism
