Abstract

The invention discloses a backup method and device for a virtual machine. The method comprises the following steps: creating a snapshot for the virtual machine to be backed up, and building a corresponding target virtual machine based on the snapshot; and exporting metadata and virtual disk information of the target virtual machine into a backup server, so that the backup server stores the metadata and the virtual disk information after performing a deduplication operation on the metadata and the virtual disk information. In the technical scheme, the virtual machine is split into the metadata and the virtual disk information, and a functional effect of backing up the virtual machine is achieved by exporting the metadata and the virtual disk information of the virtual machine, so that an exporting speed during virtual machine backup can be increased to 60-70MB/s, and the exporting speed during virtual machine backup is increased greatly. Meanwhile, backup of the virtual machine to be backed up is realized through the target virtual machine, so that services of the virtual machine to be backed up can be protected from being influenced, and normal running of the virtual machine to be backed up is ensured.

Description

Technical field [0001] The present invention relates to the technical field of server virtualization, and more specifically, to a virtual machine backup method and device. Background technique [0002] XenServer is an enterprise-level virtualization platform that has been validated in the cloud computing environment. It can provide all the functions required to create and manage virtual infrastructure; and for data security considerations, it is usually necessary to periodically check the virtual machines that exist in XenServer. Make a backup. [0003] For the latest version of xenserver, xenserver6.5, backing up the virtual machine is done by exporting a snapshot of the virtual machine. Specifically, by taking a snapshot of the virtual machine, then exporting the data corresponding to the snapshot to the backup server, and exporting the data corresponding to the snapshot At the same time, the data needs to be converted to the .xva format; however, the inventor found that exporti...
