Abstract

The invention provides a backup method, equipment and system for a virtual machine. The backup method for the virtual machine comprises the following steps that: a backup server mounts the snapshot initial volume of an original volume of the virtual machine to be backed up in a main storage device to a backup server; the backup server creates an initialization backup volume on backup storage equipment, and mounts the initialization backup volume to the backup server; the backup server backs up original data blocks of the original volume into the initial backup volume. According to the backup method, equipment and system for the virtual machine provided by the embodiment of the invention, backup processing of the virtual machine is realized through the backup server, the occupation of virtual platform resources, including main memory is reduced in a backup process, the backup disk space is saved, and the backup efficiency of the virtual machine is increased.

Description

technical field [0001] The embodiments of the present invention relate to data processing technologies, and in particular to a virtual machine backup method, device and system. Background technique [0002] With the development of computer technology, virtualization technology has been widely promoted and applied. Through virtualization technology, multiple virtual machines can be created on a physical machine to form a virtualization platform. Multiple virtual machines share physical resources, but for users, these virtual machines work exactly like real computers. [0003] The data of the virtual machine is stored on the underlying storage device. In order to ensure the reliability of the data of the virtual machine, it is usually necessary to back up the data of the virtual machine. In the prior art, for a virtualization platform that supports a cluster file system, backup of virtual machine data can be implemented by mirroring the cluster file system or storing live mig...
