Abstract

The present application relates to the technical field of virtual machines, in particular to a data backup method and device for virtual machines. Applied to a backup server, the backup server is deployed with a first component for accessing remote virtual disks and local virtual disks, and a host is deployed with several virtual machines and a second component that provides remote access to local virtual disk services, the method The method includes: sending, based on the first component, to the second component, a first message containing target virtual disk information for storing data of the target virtual machine to be backed up, so that the second component receives the first message After receiving a message, set the target virtual disk to a shared state; receive the second message sent by the second component; access the target virtual disk and the local virtual disk through the first component, from the target virtual disk Obtain data of the target virtual machine, and store the data of the target virtual machine in the local virtual disk.

Description

technical field

[0001] The present application relates to the technical field of virtual machines, and in particular, to a data backup method and device for a virtual machine. Background technique

[0002] As a mature virtualization software, QEMU is widely used to build virtualization platforms (private or public cloud) to solve the problems of waste of enterprise hardware resources and complex IT management. With the development of business, more and more enterprises and organizations have started or have migrated applications to virtualization platforms, and a large number of virtual machines have been created to run key businesses. However, how to quickly and efficiently protect important data in virtual machines, so that production data will not be catastrophically lost when disasters are 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 use the backu...
