Problems solved by technology

[0004] Using the above method, when backing up a virtual machine with a large virtual disk file, a large amount of host hard disk resources and memory resources will be occupied, causing the host to run slowly and affecting user experience
In addition, if the hard disk resources and memory resources of the host cannot meet the backup requirements, the backup will fail

Abstract

An embodiment of the invention discloses a virtual machine backup method and device. The method is used for a management server in a cluster computing system. The method comprises the following steps: receiving a backup command of a targeted virtual machine in the cluster computing system, and determining resource consumption rate of various hosts in the cluster computing system; and carrying out backup treatment on to-be-backed-up data, which are stored in shared storage equipment, of the targeted virtual machine in the cluster computing system by using at least one of the hosts according to the resource consumption rate of the various hosts in the cluster computing system and a preset strategy. Compared with a method of carrying out backup independently on the to-be-backed-up virtual machine by using the host corresponding to the to-be-backed-up virtual machine in the prior art, the virtual machine backup method can avoid the circumstances that the host runs slowly or backup fails due to the fact that hard disk resources and memory resources of the host are occupied thoroughly when a virtual magnetic disk file, which requires to be backed up, of the virtual machine is large.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a virtual machine backup method and device. Background technique [0002] Virtual machine backup is to back up the resource configuration files and virtual disk files of the virtual machine. When the virtual machine fails, use the backup file to restore the virtual machine to the state of the backup at that time. [0003] At present, the method of virtual machine backup is usually as follows: After the host receives the command to back up the virtual machine A configured on itself, it generates the virtual disk file of virtual machine A through the disk snapshot technology, and then saves the configuration file of virtual machine A and The generated virtual disk file is backed up to the specified location. [0004] Using the above method, when backing up a virtual machine with a large virtual disk file, a large amount of hard disk resources and memory resources of the host will b...
