Abstract

The invention relates to the technical field of virtual machines, in particular to a data backup method and device of a virtual machine. The method is applied to a backup server, the backup server is provided with a first component for accessing a far-end virtual disk and a local virtual disk, and a host is provided with a plurality of virtual machines and a second component for providing far-end access to the local virtual disk. The method comprises the following steps: sending a first message containing target virtual disk information used for storing data of a to-be-backed-up target virtual machine to a second component based on a first component, so that after the second component receives the first message, a target virtual disk being set to be in a shared state; receiving a second message sent by the second component; and accessing the target virtual disk and a local virtual disk through the first component, acquiring data of the target virtual machine from the target virtual disk, and storing the data of the target virtual machine to the local virtual disk.

Description

technical field [0001] The present application relates to the technical field of virtual machines, in particular to a data backup method and device for virtual machines. Background technique [0002] As a mature virtualization software, QEMU is widely used to build a virtualization platform (private or public cloud) to solve the problems of waste of enterprise hardware resources and complex IT management. With business development, more and more enterprises and organizations have begun or have migrated applications to virtualization platforms, and a large number of virtual machines have been created to run key services. However, how to quickly and efficiently protect important data in virtual machines so that production data will not be lost catastrophically when a disaster is sent has become a problem that virtualization technology needs to solve. [0003] The traditional backup method is to deploy backup software in the virtual machine, and back up the important data or a...
