Problems solved by technology

If the actual storage location of the virtual machine data disk image file is located on another cluster node, in this case, the backup of the virtual machine on the cluster master node will reduce the efficiency and increase the network overhead
In addition, if multiple virtual machines are backed up in batches on the master node of the cluster, a large amount of system IO resources will be occupied, causing the master node of the cluster to run slowly, which in turn affects the normal use of the cloud desktop server system
If the number of virtual machine batch backups is limited on the cluster master node, the efficiency of virtual machine backups will be reduced

Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0031] Such as figure 1 As shown, the present invention proposes a virtual machine backup method in a distributed storage environment, comprising the following steps:

[0032] 1) The master node of the cluster obtains at least one backup task of the target virtual machine;

[0033] 2) The master node of the cluster obtains all nodes that store the copy of the data disk image file of the target virtual machine, selects the target node according to preset rules and sends a backup command, and the target node corresponds to the target virtual machine one by one;

[0034] 3) The target node obtains the backup instruction, and executes the backup operation of the corresponding target virtual machine by creating an external snapshot of the virtual machine data disk. ...

Abstract

The invention discloses a virtual machine backup method and device in a distributed storage environment, and a storage medium. The method comprises the steps of obtaining a backup task of at least one target virtual machine by a cluster main node; enabling the cluster main node to obtain all nodes storing a target virtual machine data disk mirror image file copy, selecting target nodes according to a preset rule to send a backup instruction, wherein the target nodes are in one-to-one correspondence with target virtual machines; and enabling the target node to acquire a backup instruction, and executing a backup operation of the corresponding target virtual machine by creating an external snapshot of the virtual machine data disk. The method is used in a distributed storage cloud desktop server cluster environment, and compared with the prior art, the virtual machine backup efficiency can be improved, the network overhead can be reduced, the virtual machine does not need to be shut down during backup, the operation of a service system in the virtual machine is not influenced, and the purpose of online backup of the virtual machine is achieved.

Description

technical field [0001] The invention relates to the field of data backup, in particular to a virtual machine backup method, device and storage medium in a distributed storage environment. Background technique [0002] With the development of cloud computing, cloud desktop, as an important part of it, is becoming more and more mature, and the scope of use is becoming wider and wider. In order to prevent the loss of virtual machine data, or restore the virtual machine data to a certain point in time, virtual machine backup has become a common method. In some large-scale cloud desktop environments, cloud desktop server clusters based on distributed storage are a common solution. In this solution, the data files of the virtual machine are stored on each cluster node, but the operation of the virtual machine is generally performed on the master node of the cluster, including virtual machine backup. If the actual storage location of the virtual machine data disk image file is lo...
