Disk backup method of virtue machine

Abstract

The invention discloses a disk backup method of a virtue machine. The disk backup method includes that A, a backup server initiates backups to the virtue machine on a virtualization platform; B, the backup server communicates with the virtualization platform to inform the virtualization platform to perform snapshot operation upon the virtual machine; C), after the virtualization platform performs the snapshot operation upon the virtual machine, a motherboard of the virtual machine is parsed to obtain actual data disk sector distribution, and the virtualization platform returns the actual data disk sector distribution to the backup server; D), the backup server obtains all the actual data disk sector distribution and then backups corresponding sector data to a media server. By the disk backup method, time spent on backuping and recovering a window is enabled to be shortened, resource occupation of the virtualization platform is reduced, and more storage space is saved for customers.

Description

technical field [0001] The present application relates to the technical field of computer data storage, in particular to a virtual machine disk backup method. Background technique [0002] Virtualization technology refers to the operation of computing elements on a virtual basis rather than a real basis. Virtualization technology can expand the capacity of hardware and simplify the process of reconfiguring software. CPU virtualization technology can simulate multiple CPUs in parallel with a single CPU, allowing one platform to run multiple operating systems at the same time, and applications can run in independent spaces without affecting each other, thereby significantly improving computer work efficiency. [0003] As virtualization technology becomes more and more mature, in particular, VMware (vmware) has become bigger and stronger, and has launched a series of virtualization-related products, all of which help users solve the waste of hardware resources, complex IT mana...

Problems solved by technology

[0006] Therefore, when backing up a virtual machine based on VADP, there will be the following problems: In the case of full backup and VADP changed block tracking technology failure, incremental backup will back up the data of all sectors of the entire virtual disk , even if the actual amount of data on the virtual machine disk is small, or even an empty disk

This will not only make the backup time of virtual machine backup longer, but also the long-term virtual machine backup will affect the performance of the virtual platform itself. In the end, customers will have to provide expensive storage media for a lot of useless data, and it will also affect possible future recovery. duration
