Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] like figure 1 Shown is a work flow diagram of a backup method for a virtual machine in a cluster of the present invention, including:

[0030] Step 11, creating a plurality of virtual machines and initializing the number of backups associated with each virtual machine to be 0, and adding the virtual machines to a backup pool for managing the information of the virtual machines;

[0031] Step 12, the virtual machine newly added to the cluster is used as the master node, the number of standby nodes of the master node is initialized to zero, and step 13 is executed;

[0032] Step 13, the primary node selects an available virtual machine from the backup pool as a standby node, and the available virtual machine is a virtual machine whose backup quantity is less than a preset total backup quantity;

[0033] Step 14, adding 1 to the...

Abstract

The invention discloses a backup method and system of virtual machines in a cluster. The method includes the steps of 11, creating a plurality of virtual machines and adding the virtual machines into a backup pool; 12, using the virtual machine newly added into the cluster as a main node; 13, allowing the main node to select available virtual machines, as backup nodes, from the backup pool; 14, adding 1 to the number of the backup nodes of the main node, adding 1 to the number of backups related to the backup nodes, adding the backup nodes to the cluster, backing up the main node through the backup nodes, and performing the step 15; 15, if the number of the backup nodes related to the main node is smaller than a preset sum of the backup nodes, performing the step 13, and if not, ending step execution. The backup method and system has the advantages that the problem of service failure caused by the fact that main and backups in a traditional main and backup redundancy scheme fail at the same time can be effectively prevented; the virtual machines providing services share the backup nodes in the backup pool, and utilization rate of resources is effectively increased.

Description

technical field [0001] The invention relates to the technical field related to clusters, in particular to a backup method and system for a virtual machine in a cluster. Background technique [0002] When dealing with complex calculations or large-scale tasks, a single computer server cannot meet the load pressure, and even relying on upgrading the configuration of the server cannot meet the growing service requirements once and for all, and the cost is very expensive and there is no scalability. By increasing the number of servers, all servers are virtualized to form several virtual machines, thereby forming a virtual machine cluster, and deploying different applications to provide external services. [0003] Virtualization refers to the use of hardware or software to manage computer resources. It can reintegrate and plan existing limited resources, allocate and use them according to needs, and maximize the utilization of resources. [0004] During the running of the cluste...
