Data deleting method, device, equipment and storage medium

Abstract

The embodiment of the invention discloses a data deleting method, a device, equipment and a storage medium. The invention is applied to the field of virtual machines of cloud computing, and is specifically applied to delayed deletion processing of virtual machine snapshots generated by the virtual machines. The method comprises the following steps: when a trigger event for executing a virtual machine snapshot deletion operation is detected, obtaining at least one virtual machine snapshot of which the data state is a deleted state; obtaining a target virtual machine snapshot matched with the target computing node from the at least one virtual machine snapshot according to the parameter information of each virtual machine snapshot; and deleting the target virtual machine snapshot. By adopting the embodiment of the invention, the virtual machine snapshot is deleted in a delayed manner, and the read-write pressure of the storage cluster in the cloud computing system is effectively reduced,so that the stability of user services can be improved.

Description

technical field [0001] The present application relates to the field of cloud computing, and in particular to a data deletion method, device, equipment and storage medium. Background technique [0002] In a cloud computing environment, user services run in virtual machines, that is, user data is stored in virtual machines. A virtual machine snapshot is a data copy of the virtual machine disk data at a certain point in time, through which the virtual machine disk data can be rolled back to the previous point in time. [0003] In order to protect the security of virtual machine data, it is often necessary to make regular automatic snapshots. For example, it is set to take snapshots of all virtual machines in the cloud computing system at 12 o'clock every night, and the scheduled automatic snapshots often only keep the latest few snapshots, for example, keep the last 5 virtual machine snapshots, and create the sixth snapshot. At this time, the first virtual machine snapshot ne...

Problems solved by technology

[0004] However, in the process of timing automatic snapshots using the above method, when it is detected that the sixth virtual machine snapshot is being made, multiple virtual machines appear in the entire cloud computing system at the same time and delete the respective first virtual machine snapshots , at this time, the reading and writing pressure of the storage cluster in the cloud computing system will increase, and the virtual machine request reading and writing will be stuck, which will affect the virtual machine and cause user business interruption
