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...
