Embodiment Construction

[0023] A cloud data backup system includes a cloud computing server and a cloud data backup server, wherein the cloud data backup server is a virtual tape library.

[0024] The virtual tape library is composed of multiple RAID-based disk arrays to form a distributed file storage system.

[0025] The virtual tape library adopts a multi-controller parallel architecture, which realizes the online dynamic horizontal expansion of the controllers, and the system performance increases exponentially with the growth of the controllers. The virtual tape library is specially customized for high-end enterprise users. It is based on a multi-controller parallel architecture, and the back-end uses a distributed file system as storage. Through parallel technology, the online dynamic horizontal expansion of the controller is realized, and the system performance is multiplied even though the controller grows; while the back-end distributed storage provides dynamic horizontal expansion of the ca...

Abstract

The invention relates to a data backup system, in particular o a cloud data backup system. The cloud data backup system comprises a cloud computing server and a cloud data backup server, wherein the cloud data backup server is a VTL (Virtual Tape Library); the VTL consists of a plurality of disk arrays based on RAID (Redundant Array of Independent Disks) protection, and a distributed file storage system is formed; the VTL adopts a multi-controller parallel architecture, and realizes the on-line dynamic horizontal expansion of controllers; and the system performance is exponentially improved along with the increase of the controllers. The VTL used by the data backup system uses the multi-controller parallel architecture, and the distributed file storage system is used as a memory at the back end. Through a parallel technology, the on-line dynamic horizontal expansion of the controllers is realized, and the system performance is exponentially improved along with the controller increase; the dynamic horizontal expansion of the capacity is enabled through the back end distributed memory; during the capacity expansion, the inside I / O (input / output) speed is greatly accelerated, so that a qualitative leap of the integral performance of the VTL is achieved.

Description

technical field [0001] The invention relates to a data backup system, in particular to a cloud data backup system. Background technique [0002] The rapid development of virtualization, cloud computing, and big data technology has changed the application mode of traditional IT. With the implementation of the cloud, more users focus on cloud applications, cloud computing, cloud storage, etc., and gradually ignore the cloud environment. data protection. When users are deploying cloud computing, since the computing and storage of cloud computing data are carried out on the cloud platform, the data in the cloud will be more important. Apart from the reasons of data privacy and network attacks, complex system structure, multi-user thin terminal Application environment, virtualized application mode, huge storage devices, and massive data backup also bring new challenges to cloud data protection. [0003] In October 2009, Microsoft's Sidekick mobile service failed, making users u...
