Abstract

The invention relates to a virtual server backup and restoration method based on a storage volume level. The method comprises the following steps: acquiring disk capacity in a virtual machine and to-be-backed-up information in a disk; a storage platform is established, the storage platform is provided with an LUN backup disk with the same capacity as the disk, and the LUN backup disk is provided with a plurality of storage volume levels used for conducting hierarchical backup on the to-be-backed-up information; respectively storing the logic levels of the information to be backed up into different storage volume levels, and enabling the information stored in the LUN backup disk to be the same as the disk content in the virtual machine so as to complete the backup of the disk content; and performing virtual snapshot on the LUN backup disk, so that the disk content is recovered according to the content of the virtual snapshot when the disk content is damaged. The to-be-backed-up data can be effectively and virtually stored, a storage platform does not need to be emptied, and the backup efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of virtual storage, in particular to a method for backing up and restoring virtual servers based on storage volume levels. Background technique [0002] With the continuous maturity of cloud computing technology, private cloud has become the preferred technology for data centers instead of physical servers. Through server virtualization, server hardware resources can be used more effectively, the utilization rate of data center computing resources can be improved, and data center maintenance and operation can be reduced. the cost of. The backup and restoration are usually completed by using a backup program. The backup program refers to a program for backing up data in the system, and the backup program is a basic program in the system. [0003] During the backup process, the backup program establishes a connection with the virtual machine to be backed up, creates a snapshot of the files in the virtual mach...
