Embodiment Construction

[0023] refer to Figure 1-4 .

[0024] In the present invention, the objects in the backup system are divided into different roles according to the division of labor, and several components such as feature code management, backup management and data acquisition are provided. During the backup process, these components perform corresponding tasks for different roles. The different components deployed in each role according to the division of labor coordinate and cooperate with each other to complete the whole process of backup processing.

[0025] Objects in the system play three roles: source end, target end, and cloud.

[0026] Source end: End users who have data backup needs are the actual users of data, and in most cases may be individual users. Establish a network communication path directly with the target.

[0027]Target end: The data center that provides backup services for the source end. Generally, it provides computing services for the source end and other end use...

Abstract

The invention discloses a data backup acceleration method for a cloud storage system, aiming to solve the technical problem of low efficiency of existing data backup methods for the cloud storage system. The technical scheme includes periodically uploading data to and downloading data from other network nodes of a data center by network crawler programs and calculating hash values of data, deleting repeating data of data of a client side according to the hash values before data backup, searching repeating data of the client side from existing data and cloud data of the data center by means of comparison of the hash values during data backup, further compressing volume of the data needed to be copied to the data center from the client side, and backing up data to the data center from the network nodes of the client side while backing up the data to the data center from the client side according to the high broadband of the data center and the shared cloud data; thereby, minimizing the data volume transmitted by the network between the specific user and the data center and then accelerating the data backup process and effectively increasing storage utilization rate of the data center.

Description

technical field [0001] The invention relates to a data backup method of a cloud storage system, in particular to a data backup acceleration method of a cloud storage system. Background technique [0002] As the amount of personal data grows, data disaster recovery backup becomes increasingly important. In daily life, disasters can happen at any time. Power outages, fires, floods, and even hard drive failures can destroy all locally stored data. Therefore, users need to choose remote backup or store copies of files in cloud storage to keep their data safe from disaster. The online backup service is Internet-based and can automatically back up selected files. These files are stored in the cloud and can be accessed at any time, any place, and any terminal. The user's working environment presents the characteristics of mixing and diversification, cross-platform and even cross-region. For example, some users use different methods (including mobile phones, laptops, and tablet ...
