Embodiment Construction

[0040] The core of cloud storage is the combination of application software and storage devices, and the transformation from storage devices to storage services is realized through application software. Compared with traditional storage devices, the cloud storage system involves not only hardware, but a complex system composed of network devices, storage devices, servers, application software, public access interfaces, access networks, and client programs. . Each part takes the storage device as the core, and provides data storage and business access services to the outside world through application software.

[0041] Big data is often used to describe the large amount of unstructured and semi-structured data created by an enterprise that would take too much time and money to download to a relational database for analysis. Big data analysis is often associated with cloud computing, because real-time analysis of large data sets requires a framework like MapReduce to distribute...

Abstract

The invention discloses a data backup method and a data backup device of a cloud storage system. The data backup method of the cloud storage system comprises the following steps of: recording modification conditions of a target data set of a client; determining a difference part of current content and backed-up content of the data set according to the recorded modification condition; and after receiving a backup operation trigger instruction, performing backup operation on the determined difference part. By applying the technical scheme provided by the embodiment of the invention, backup of a user file system at the client can be effectively managed, the operation of a user is effectively facilitated in an automatic backup mode, and the manual cost on the user side is reduced. The backup of a large amount of repeated contents each time is avoided in an incremental backup mode, so that the occupation of backup time and backup space is reduced.

Description

technical field [0001] The invention relates to the technical field of cloud storage, in particular to a data backup method and device for a cloud storage system. Background technique [0002] 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 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 will be transformed into a cloud storage system, so cloud storage is a data storage and management as the core cloud computing system. ...
