The invention discloses a
virtual machine backup method and
system, and the method comprises the steps: firstly analyzing a FusionCmopute management platform interface, obtaining
backup data of a plurality of virtual machines, then sending a first request message comprising a global
unique identifier VMID of the plurality of virtual machines on the management platform to a FusionCmopute platform, calling the
resource use conditions of the plurality of virtual machines, and storing the
resource use conditions of the plurality of virtual machines in the FusionCmopute management platform; the virtual machines are backed up on the basis of the
resource use condition, when the resource use condition of the first
virtual machine does not reach a preset threshold value, a
backup task is initiated on the basis of backup data, and the first
virtual machine is backed up to a corresponding backup storage position. According to the technical scheme, automatic backup of the virtual machines can be achieved, the virtual machines do not need to be manually backed up one by one, backup of the virtual machines is carried out when it is confirmed that the backup task can be executed according to the resource use condition, the risk of backup failure caused by resource conflicts is avoided, and therefore the reliability and efficiency of the backup task are effectively improved.
