Problems solved by technology

[0003] In related technologies, the solution for realizing online P2V migration is to migrate the disk data at the snapshot time point to the cloud platform through Volume Shadow Copy Technology (Volumn Shadow Copy Service, VSS) without interrupting the customer's business, while migrating the data During the process, the changed data on the disk is temporarily saved, and the data is synchronized after the VSS snapshot data transmission is completed. If new changed data is generated during the data synchronization process, the synchronization needs to be repeated, and the data is cyclically synchronized until the range of lost data is acceptable. Shut down the physical machine later, and in turn, the disk data of the physical machine is inconsistent with the disk data of the virtual machine, and affects the efficiency of data migration

Embodiment Construction

[0047] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0048] The embodiment of the present invention provides a technical solution for data migration, which can realize data migration between a physical machine and a cloud platform, such as online P2V migration between a physical machine and a cloud platform; figure 1 It is a schematic diagram of an application scenario of an embodiment of the present invention, such as figure 1 As shown, a physical machine is a name for a physical computer relative to a virtual machine on the cloud platform. The physical machine can provide a certain hardware environment for the virtual machine, and is sometimes called a "host" or "host". Cloud platform, also known as cloud computing platform, refers to a service platform based on hardware resources and software resources, which can provide computing, network and storage capab...

Abstract

The embodiment of the invention provides a data migration method which is applied to a physical machine and comprises the following steps: acquiring disk information of the physical machine, sending the disk information to a cloud platform, receiving a shared mirror image shared by the cloud platform according to the disk information, and loading the shared mirror image of the cloud platform; andin the process of migrating snapshot data to a cloud platform, copying the data written into the disk of the physical machine into the shared mirror image. Thus, the data migration method can synchronize the data of the disk of the physical machine to the cloud platform without loss; meanwhile, the synchronization process of the data written into the disk is carried out simultaneously in the snapshot data migration process, so that the data migration efficiency is improved. The embodiment of the invention further discloses another data migration method, a physical machine, a cloud platform anda computer storage medium.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data migration method, device, physical machine, cloud platform and computer storage medium. Background technique [0002] Online P2V migration (Online physical to virtual migration, P2V), also known as P2V hot migration, refers to the technology of migrating disk data from a physical machine to the cloud platform without interrupting the customer's business. By migrating the disk data of the physical machine to the cloud In the virtual machine of the platform, the data synchronization between the physical machine disk and the virtual machine disk is realized. [0003] In related technologies, the solution for realizing online P2V migration is to migrate the disk data at the snapshot time point to the cloud platform through the volume shadow copy technology (Volumn Shadow Copy Service, VSS) without interrupting the customer's business. During the process, the ch...
