Problems solved by technology

[0005] It can be seen from the above that the large amount of data of the virtual machine leads to low efficiency of virtual machine backup, so how to improve the efficiency of virtual machine backup while protecting all application data in the virtual machine has become a problem that backup vendors have been determined to solve. contradictory issue

Embodiment

[0024] figure 1 It is a flow chart of the traditional hyper-v virtual machine backup method. With this backup method, since the disk files of the virtual machine are not filtered every time the backup is performed, even if there are many virtual machine disks that have not changed If the files exist, all of them will be backed up to the media server for each backup, which will lead to low backup efficiency and low storage usage of the media server.

[0025] And then of the present invention can effectively solve the problems referred to above, its concrete process is as follows figure 2 As shown, it specifically includes the following steps:

[0026] 1. Create a hyper-v virtual machine backup task.

[0027] 2. A full backup is performed on the backup task, and a backup knowledge base is established according to the attribute information of the backup virtual machine disk file. The content of the backup knowledge base mainly includes the identifier of the virtual machine to...

Abstract

The invention discloses a hyper-v virtual machine backup method based on a backup knowledge base and file attributes. Through a hyper-v backup process, the backup knowledge base is established for hyper-v backup magnetic disk files, when backup is carried out again, information such as the attributes of the hyper-v virtual machine magnetic disk files and the backup knowledge base established before are compared, accordingly, whether the magnetic disk files change is determined, whether backup anew is needed is determined, and therefore the purposes that the hyper-v virtual machine backup data amount is lowered, backup efficiency is improved, and backup storage is lowered are achieved. Compared with the prior art, the each-time virtual machine backup data amount can be lowered under multiple situations, virtual machine backup efficiency is improved, occupation of hyper-v virtual platform resources is lowered, and the storage space of a user is saved.

Description

technical field [0001] The invention relates to a data backup method, in particular to a hyper-v virtual machine backup method based on a backup knowledge base and file attributes. Background technique [0002] Currently, as virtualization technology becomes more and more mature, more and more enterprises and organizations deploy applications on virtual machines of virtualization platforms, such as Microsoft's hyper-v virtualization platform, so how to protect these The application data deployed on the virtualization platform has become one of the most concerned issues of these enterprises and organizations. [0003] The virtual machine has a very useful function: snapshot. The snapshot can save all the data of the virtual machine at a certain point in time. When appropriate, the virtual machine can be restored to the state of the previous point in time. The virtual machine is taking a snapshot , a sub-disk will be created on the basis of the current disk, so as to keep the...
