Virtual machine backup method and device, electronic equipment and readable storage medium

Abstract

The invention discloses a virtual machine backup method and device, electronic equipment and a computer readable storage medium, and the method comprises the steps: updating offset information corresponding to a target virtual machine if a target coroutine is detected, wherein the target coroutine is any coroutine in an idle state in the plurality of coroutines; based on the offset information, reading corresponding to-be-backed-up data by utilizing the target coroutine; writing the to-be-backed-up data into the target position by utilizing the target coroutine; according to the method, in theprocess that a target coroutine reads to-be-backed-up data, other coroutines can also read the data; or read data can be written into the target coroutine, and other coroutines can read or write thedata in the process of writing the data into the target coroutine, so that concurrent processing of virtual machine backup is realized; and multiple coroutines are subjected to concurrent processing,so that the data reading speed and the data writing speed are greatly increased, the virtual machine backup speed is increased, and the backup time is shortened.

Description

technical field [0001] The present application relates to the technical field of virtual machines, and in particular to a virtual machine backup method, a virtual machine backup device, electronic equipment, and a computer-readable storage medium. Background technique [0002] In a virtualized environment, backing up virtual machines is an important mechanism for service assurance. When the running storage of the virtual machine fails or the virtual machine is invaded by a virus, the backup file of the virtual machine can be used to achieve quick recovery, avoiding data loss and long-term business interruption. In related technologies, when backing up a virtual machine, the backup speed is relatively slow, which is much lower than the storage throughput speed, so the required backup time is longer and the backup efficiency is lower. Contents of the invention [0003] In view of this, the purpose of this application is to provide a virtual machine backup method, a virtual ...
