Abstract

The invention provides a mirror image backup method and device of a virtual machine, a fault recovery method and device of a virtual machine and electronic equipment. The mirror image backup method ofthe virtual machine comprises the steps: obtaining mirror image data, needing to be backed up, of the virtual machine if the virtual machine created on a host machine is in an online state; and backing up the mirror image data to block equipment corresponding to the virtual machine in the distributed storage cluster. According to the method, if the virtual machine created on the host machine is in the online state, the mirror image data needing to be backed up by the virtual machine is obtained, and the mirror image data is backed up to the block device corresponding to the virtual machine inthe distributed storage cluster. As the backup of the mirror image data is not stored locally in the host machine, not only can the local storage space of the host machine be saved, but also the reliability of the backup data of the mirror image of the virtual machine can be improved.

Description

technical field [0001] The present application relates to the technical field of computer virtualization, in particular, to a virtual machine image backup method, fault recovery method, device and electronic equipment. Background technique [0002] A virtual machine (Virtual Machine) refers to a complete computer system that is simulated by software and has complete hardware system functions and runs in a completely isolated environment. The physical machine that actually runs the virtual machine is called a host machine, and one or more virtual machines can run on one host machine. Each virtual machine can have one or more images. In order to improve the reliability of the virtual machine image, it is usually necessary to back up the image data of the virtual machine. [0003] The backup data of the existing virtual machine image is generally saved locally on the host machine. On the one hand, the data reliability of the virtual machine image is highly related to the usag...
