Problems solved by technology

[0004]However, in this memory snapshot method, the backup time of the memory part data is relatively long, and the IO resources of the virtual machine and the cloud platform level are occupied at the same time when the memory data file is saved IO resources, the creation of snapshots takes a long time, and cannot be applied to application scenarios with high memory snapshot efficiency

Embodiment approach

[0051] It is understandable that if the virtual machine is mounted on a disk with many blocks, the snapshot backup of related technologies cannot ensure the consistency of multiple disk snapshots, and cannot be applied to business scenarios that require high data backup accuracy such as time point and data. . Based on this, the storage volumes corresponding to the multiple disks mounted by the virtual machine can be placed in the same consistency group in advance, and the virtual machine can provide a consistent snapshot implementation interface for the storage layer built on the storage disk. The snapshot interface creates snapshots for a group of disks, ensuring that the created disk snapshots are all data at the same precise point in time. like image 3 As shown, an implementation manner of S103 may include the following steps:

[0052] S1031: Determine whether the number of disks mounted on the target virtual machine is a single disk or multiple disks, if it is a single ...

Abstract

The invention discloses a memory snapshot method and a device of a cloud computing platform virtual machine based on a storage system, and a computer readable storage medium. A memory synchronizationinterface matched with each virtual machine operating system is constructed in advance; wherein the memory synchronization interface is used for synchronizing memory data at a preset moment to a corresponding storage disk, and the method can comprise the following steps: when a target virtual machine snapshot creation operation instruction issued by a cloud platform is received, obtaining storageresources which are mounted on a target virtual machine and comprise a disk and a storage volume corresponding to the disk on a storage system; sending an instruction of interrupting the storage resource read-write request, and meanwhile, calling a memory synchronization interface matched with the target virtual machine to synchronize the memory data into the disk; based on the corresponding relation between the disk and the storage system, calling the snapshot interface of the storage system to carry out snapshot operation on the disk, so that the memory snapshot of the virtual machine is efficiently realized on the basis of not occupying IO resources of the virtual machine and IO resources of a cloud platform.

Description

technical field [0001] The present application relates to the technical field of storage snapshots, and in particular, to a memory snapshot method, device and computer-readable storage medium of a cloud computing platform virtual machine based on a storage system. Background technique [0002] With the rapid development of cloud computing and big data, distributed cloud computing is widely used in storage systems. In a distributed cloud computing scenario, snapshot data backup based on SAN (Storage Area Network, storage area network) storage is an inevitable part, and the object is computing resources built on SAN storage, that is, virtual machines. The data backup of the virtual machine not only includes the backup of the data of the disk itself, but also includes the backup of the data in the memory. The data in the memory refers to the data in the memory and has not been actually written to the disk. [0003] In the related art, when taking a memory snapshot of a virtual...
