Problems solved by technology

[0003] The existing virtual machine recovery technology is limited by network bandwidth and data backup format. If the data of the virtual machine is backed up on the cloud server, it is necessary to download all the backup data to the virtual machine first, and then start the virtual machine
Due to the large amount of data in the virtual machine, it takes several hours to several days to restore all the backup data of the virtual machine to the virtual machine, which takes a long time and the recovery efficiency of the virtual machine is low.

Embodiment Construction

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0050] At present, remote backup data cannot be directly used for the recovery of virtual machines. There are two core technical problems that the recovery technology of virtual machines cannot support remote backup data. 240Mbps) bandwidth requirement, and the existing remote data access bandwidth often cannot meet this requirement, so that the remote backup data cannot be directly used for the recovery of the virtual machine. The second is: remote backup data is ...

Abstract

The embodiment of the invention discloses a virtual machine recovery method which is applied to a virtual machine management device. The method comprises the steps that a virtual machine recovery command is received, configuration information of a recovered virtual machine is obtained from a cloud sever, and a recovery virtual machine and a local storage unit corresponding to the recovery virtual machine are created according to the configuration information; a start command of the virtual machine is received, basic system data is obtained and downloaded from the cloud server, and the recovery virtual machine is started according to the basic system data; an IO request is received, whether data related to the IO request is stored in the local storage unit or not is determined, if not, the data related to the IO request is downloaded to the local storage unit from the cloud server, and the data requested by the IO request is returned. The embodiment of the invention further discloses the virtual machine management device. The virtual machine management device has the advantage of being capable of improving the recovery efficiency of the virtual machine.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a virtual machine recovery method and a virtual machine management device. Background technique [0002] As enterprise servers are increasingly shifted to virtualization platforms, physical servers have become virtual machines, and modern backup software has also enhanced the ability to protect virtual machines. In order to prevent damage or loss of virtual machine data caused by disasters such as fires, floods, and earthquakes, virtual machine data is often backed up or copied to off-site backup storage space, for example, the local data of the virtual machine is backed up or copied to a cloud server . When a disaster occurs, the data of the virtual machine can be downloaded from a backup storage space such as a cloud server to restore the virtual machine. [0003] Due to the limitation of network bandwidth and data backup format in the existing virtual machine recovery...
