Problems solved by technology
For IO-intensive virtual machines, such as virtual machines for front-end applications or databases, processing IO requests most of the time, these virtual machines will take longer to create snapshots; and for virtual machines used as large database storage , with a large number of large disk files, these disk files exceed the concurrent computing power of the CPU of a single proxy node, and will consume more time in the process of backing up the disk

The invention discloses a virtual machine backup scheduling method, system and device and a storage medium. The virtual machine backup scheduling method comprises the following steps: acquiring a virtual machine backup task; splitting the virtual machine backup task into a plurality of first sub-tasks and second sub-tasks; evaluating the time consumption of the first subtask to generate a first weight; evaluating the time consumption of the second subtask to generate a second weight; constructing a first chromosome according to the first subtask and the second subtask; calculating first fitness according to the first weight and the second weight; selecting the first chromosome with the highest first fitness as a second chromosome, and returning to the step of calculating the first fitness according to the first weight and the second weight until the second fitness is converged; and generating a virtual machine backup scheduling scheme according to the second chromosome. According to the method, more comprehensive and more detailed virtual machine backup scheduling is realized, the node performance is fully utilized, and the overall time consumption of the virtual machine backup task is shortened.
Description
technical field [0001] The present application relates to the technical field of backup, in particular to a virtual machine backup scheduling method, system, device and storage medium. Background technique [0002] The traditional virtual machine concurrent backup system consists of a cluster consisting of a backup server, a storage server, and multiple agent-side working nodes. In the traditional virtual machine backup process, the backup server first assigns each virtual machine to a certain node of the cluster, and then each node starts to back up the virtual machine disks serially or in parallel. Obviously, this virtual machine backup solution does not take into account the business differences between virtual machines. Virtual machine backup mainly includes two processes of creating a snapshot and backing up a virtual disk, wherein creating a snapshot can be further divided into two processes of freezing a virtual machine file system and creating a snapshot subdisk. T...
