Abstract

The invention discloses a virtual machine snapshot management method, device, device and storage medium. The method includes: when generating snapshot data, generating initial snapshot data in a business cluster, and performing data processing through a transfer node to obtain The target snapshot data is uploaded to the backup cluster for storage. When rolling back the snapshot data, output the target snapshot data from the backup cluster, then input it into the business cluster, and reset the virtual machine to complete the rollback of the snapshot data. The method can comprehensively process data disks and system disks by setting up backup clusters based on business clusters, and avoids the problem of affecting memory read and write performance when copying data in full within the cluster when only business clusters exist . The method can also prevent the loss of the snapshot data by setting the backup cluster and saving the data in the backup cluster.

Description

technical field [0001] The present invention relates to the field of virtual machine snapshots, in particular to a virtual machine snapshot management method, device, device and storage medium. Background technique [0002] In the cloud computing platform, the data backup and recovery mechanism is an important system function. A copy of the disk file of the virtual machine at a certain moment is generated through the snapshot operation, and the data of the disk file can be restored through the copy. When the system crashes or the system is abnormal, you can restore the disk file system and system storage by using the snapshot. When upgrading applications and servers and patching them, virtual machine snapshot files are also required to save data information at the current moment. [0003] When performing a virtual machine snapshot operation, usually a full copy of the system disk of the virtual machine is made, and then uploaded to the image service as a snapshot, and the v...
