Embodiment Construction

[0015] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0016] figure 1 It is a schematic diagram of an embodiment of the cloud storage system writing data normally.

[0017] First, before data is extracted from the cloud storage environment, data is usually written to multiple storage clouds of the cloud storage system. In a normal use environment, the cloud storage system will write data based on the nearest principle, such as figure 1 The shown example of normal data wri...

Abstract

The invention relates to a data extraction method applied to a cloud storage system comprising a first extraction management server, a main storage cloud and a plurality of slave storage clouds. The method comprises the steps as follows: the first extraction management server receives a data extraction request sent by a user terminal, wherein the data extraction request comprises storage position information of target data to be extracted; the first extraction management server determines the corresponding main storage cloud according to the storage position information, and sends the data extraction request to the main storage cloud; the main storage cloud acquires data index information corresponding to the target data to be extracted according to the data acquisition request; and the main storage cloud extracts the target data from the main storage cloud or the plurality of corresponding slave storage clouds based on the data index information, and sends the target data to the user terminal. According to the method and the system provided by the invention, under the cloud storage environment, data extraction efficiency is improved by improving an index retrieval speed and a data dispersed extraction strategy.

Description

technical field [0001] The invention belongs to the technical field of data storage and calling, and in particular relates to a data extraction method and system. Background technique [0002] Cloud storage is a concept extended and developed from the concept of cloud computing. It is a new network storage technology. Through the functions of cluster application, network technology or distributed file system, a large number of different types of storage in the network A system in which devices work together through application software to jointly provide data storage and business access functions. [0003] With the development of science and technology, the scale of cloud deployment is getting larger and larger, and the amount of data is increasing by the order of tens of millions. At the same time, users have higher and higher requirements for cloud storage performance and application experience. [0004] When the data requested by the user is stored in multiple storage cl...
