Embodiment Construction

[0028] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0029] see figure 1 , is a functional hierarchical structure diagram of an embodiment of the method and device for controlling data redundancy in cloud storage according to the present invention.

[0030] The first layer is the end user layer 100, which includes all end users who use cloud storage services. This layer mainly includes an interface management module 101, a query module 102, and a summary extraction module 103, wherein:

[0031] The interface management module 101, which is connected to the cloud storage layer interface module 111 through the network, is responsible for data transmission, analyzes the information issued by the cloud storage layer, transmits data or transfers the information issued by the cloud storage layer to the corresponding subsequent processing module, and forwards it to the subsequent processing module Upload information to the cl...

Abstract

A method and device for controlling data redundancy in cloud storage. The core of the present invention is to create a corresponding virtual data copy counter for each stored data in the cloud storage layer and write it into an associated database together with other relevant information such as the data summary and storage location. The terminal user uploads the summary of the operated data before requesting the data operation; if there is a virtual data copy counter associated with the summary of the operated data, the user's upload, delete and other operations are converted into operations on the virtual data copy counter ( Upload is transformed into a virtual data copy counter plus one, and deletion is transformed into a virtual data copy counter minus one); if the summary of the manipulated data has no virtual data copy counter associated with it, the end user needs to upload the manipulated data, and in the associated Relevant information is saved in the database; at the same time, the associated database will also save the name (such as: file name, data table name, etc.) of the data represented by the summary in the end user's local storage, so that the end user can query, download, and delete.

Description

technical field [0001] The invention relates to the field of cloud storage, that is, a network-based method and device for controlling data redundancy in cloud storage, which is composed of several servers and several network storage devices and reduces data redundancy and network resource waste. 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 wi...
