KVM virtualization-based agency mode-free backup method and system

Abstract

The invention relates to the technical field of database backup and recovery, in particular to a KVM virtualization-based agency mode-free backup method. The method comprises the steps of registering a host, in which a virtual machine needed to be backed up is located, in a web disaster recovery backup management system; creating a backup task; starting the backup task; creating a quick recovery task; and starting the quick recovery task, thereby realizing data backup and quick recovery. The invention furthermore provides a KVM virtualization-based agency mode-free backup system. The system comprises the web disaster recovery management system for managing the whole backup recovery process, the host comprising two or more virtual machines, and a backup server for backing up disk files and configuration files of the virtual machines. According to the method and the system, agency mode-free backup is adopted, so that system deployment and personnel maintenance costs are greatly reduced; and second-level quick recovery of the virtual machines is supported, so that enterprise application stop time is shortened and enterprise loss is reduced.

Description

technical field [0001] The invention relates to the technical field of backup and recovery of databases, in particular to an agentless mode backup method and system based on KVM virtualization. Background technique [0002] With the improvement of our country's informatization level, the localization of software has become an important part of national security. Domestic operating systems based on the Linux kernel, including Hongqi Linux and Kirin, have been highly valued and promoted by relevant state departments. As the native KVM of the Linux kernel, it is bound to become the first choice for domestic virtualization platforms. [0003] Although KVM has been extensively researched and applied in the field of server virtualization, its stability and reliability are slightly inferior because it came out later than VMware and XEN. KVM itself does not provide reliability protection for upper-layer virtual machines. Some data backup vendors at home and abroad provide backup p...

AI Technical Summary

Problems solved by technology

KVM itself does not provide reliability protection for upper-layer virtual machines. Some data backup vendors at home and abroad provide backup protection solutions for KVM virtual machines, but most of them require the installation of backup agents on the guest operating systems of virtual machines. Greatly increase system deployment and personnel maintenance costs, and easily affect enterprise applications and operating systems

In addition, traditional kvm virtual machine backup vendors do not provide fast recovery function, which will increase the time of enterprise application interruption and cause more losses for enterprises
