Problems solved by technology

When using a virtual machine, all the storage systems in the virtual machine will be encapsulated into a file, and the virtual machine snapshot created is mixed with memory information. Once the virtual machine system crashes, the virtual machine snapshot will also be damaged, and the user's Data is hard to restore

Embodiment Construction

[0034] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0035] like figure 1 As shown, it is a schematic structural diagram of a virtual machine backup system in a cloud computing system of the present invention. The cloud computing system is provided with a virtual machine and a backup server group, the backup server group is connected with the virtual machine, and the virtual machine is provided with a file backup system. Functional backup client.

[0036] The cloud computing system is provided with a snapshot making module, which is used to make snapshots for the running virtual machines to be backed up; the backup server cluster is provided with a snapshot storage and restoration module for storing snapshots, which is connected with the snapshot making module; in the cloud computing system An encryption module is also provided for encrypting the backup files received through the...

Abstract

The invention discloses a backup method and a system of a virtual machine in a cloud computing system. A backup server farm is arranged in the cloud computing system. The method comprises: restoring is performed on the backup server farm according to the virtual machine needed to be backed up to obtain a new virtual machine which is the same as the virtual machine needed to be backed up; the cloud computing system calls the new virtual machine to back up files needed to be backed up in the new virtual machine into the cloud computing system; the new virtual machine is closed and destroyed after the backup is completed. According to the invention, after virtual machine snapshots, duplicated incremental mirror images or duplicated mirror images are used to restore and obtain a new virtual machine, files backup is performed the backup server farm to ensure virtual machine files that a user most concerns about can be backed up safely; furthermore, a backup client on the virtual machine is utilized for backup, even through an error occurs during backup, the snapshots or incremental mirror images / mirror images of the original virtual machine of a user are not damaged, such that the safety of original virtual machine of the user is guaranteed, and safety backup of the virtual machine of the cloud computing system is realized.

Description

technical field [0001] The invention relates to cloud computing applications, in particular to a virtual machine backup method and system in a cloud computing system. Background technique [0002] Cloud Computing is Grid Computing, Distributed Computing, Parallel Computing, Utility Computing, Network Storage Technologies, Virtualization , Load Balance (Load Balance) and other traditional computer technology and the product of the integration of network technology development. It aims to integrate multiple relatively low-cost computing entities into a perfect system with powerful computing power through the network, and uses SaaS (Software-as-a-service), PaaS (Platform-as-a-Service), Advanced business models such as IaaS (Infrastructure as a Service) and MSP (Managed Service Provider) distribute this powerful computing power to end users. [0003] From the above, cloud computing is built on virtualization, and its realization relies on virtualization technology as the found...
