Furthermore, the terms "comprising" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions.

Having described the technical solutions of the embodiments of the present invention, various non-limiting embodiments of the present application are described in detail below.
Referring to fig. 1, fig. 1 is a schematic flow chart of a memory snapshot method for a cloud computing platform virtual machine based on a storage system according to an embodiment of the present invention, where the cloud computing platform based on the storage system builds a system network topology according to a topology structure shown in fig. 2, and creates corresponding storage resources and virtual machine resources according to a schematic topological relation shown in the figure. In order to implement a subsequent snapshot function, the virtual machine provides a snapshot implementation interface for a storage layer established on the storage disk, such as a system disk, a data disk, and the like of the storage system; on the operating system level of the virtual machine, a memory synchronization interface is provided or written in advance, and memory data at a certain moment can be synchronized into a corresponding storage disk; that is, a plurality of memory synchronization interfaces matched with each virtual machine operating system may be constructed, and memory data at a preset time may be synchronized to a corresponding disk by calling the memory synchronization interfaces. The execution subject of the following embodiments is a storage system, and the embodiments of the present invention may include the following:
s101: and when a target virtual machine snapshot creation operation instruction issued by the cloud platform is received, acquiring the mounted storage resource of the target virtual machine.
In the application, when the snapshot operation is required, the cloud platform layer initiates the snapshot creation operation on a certain virtual machine, issues the instruction to the disk through an interface provided by the virtual machine operating system, and the storage system executes the snapshot operation. Before the snapshot operation needs to be performed, which storage disks are mounted by the virtual machine and the storage volumes of the disks on the storage system, that is, the storage resources in S101, may be collected according to an interface provided or developed by the cloud platform. For convenience of description, in the embodiment of the present invention, the virtual machine is referred to as a target virtual machine.
S102: and sending an instruction for interrupting the read-write request of the storage resource, and calling a memory synchronization interface matched with the target virtual machine to synchronize memory data to a disk.
It can be understood that, the memory synchronization interfaces of the operating systems of different virtual machines are different, different memory synchronization interfaces may be developed in advance according to different types of operating systems, then the type of the target virtual machine in the operation instruction is created according to the target virtual machine snapshot of S101 to match the corresponding memory synchronization interface, and then the memory data synchronization computer program executed correspondingly by the memory synchronization interface is flushed to the corresponding disk.
S103: and calling a snapshot interface of the storage system to perform snapshot operation on the disk based on the corresponding relation between the disk and the storage system.
In order to ensure normal operation of the memory snapshot characteristic, an operation authority of IO interruption needs to be provided, after the cloud platform calls an interface provided by the virtual machine operation system to issue a corresponding IO to a disk, an instruction for interrupting a read-write request of a storage resource is sent based on S102 to perform IO (input/output) interruption on all the disks, then a snapshot interface provided by the storage system is immediately called to perform a snapshot operation on a storage system volume, and after a snapshot is successful, a virtual machine data backup including memory data at this time point is completed.
It should be noted that the IO interruption of the disk is automatically recovered after the snapshot is completed, the IO interruption time of the disk may be set according to the actual application scenario, counting is performed by using a counter from the instruction time of sending the read-write request for interrupting the storage resource, and the IO of each disk may be automatically recovered after the IO interruption time is reached.
In the technical scheme provided by the embodiment of the invention, under a cloud computing architecture, virtual machine snapshot operation created based on a storage system is downloaded to the storage system for execution, corresponding memory data synchronization interfaces are provided according to different operating systems to synchronize memory data to a disk, and IO interruption operation authority needs to be provided, so that when the snapshot is created, the memory data is synchronously downloaded to the corresponding disk, normal operation of memory snapshot characteristics is ensured, the memory snapshot operation can be processed and completed in a short time, because IO interruption time is short, the influence on virtual machine service can be reduced to the minimum, and the memory data can be rapidly and efficiently transferred and the memory snapshot operation can be realized on the basis of not occupying IO resources of a virtual machine and IO resources of a cloud platform.
It can be understood that, if there are many blocks in the disk mounted by the virtual machine, the snapshot backup in the related art cannot ensure the consistency of the snapshots of the multiple disks, and cannot be applied to a service scenario with high requirements for data backup accuracy, such as a time point and data. Based on the method, the storage volumes corresponding to the plurality of disks mounted by the virtual machine can be placed in the same consistency group in advance, the virtual machine can provide a consistency snapshot realization interface for a storage layer surface established on the storage disks, and the consistency snapshot interface carries out snapshot creation aiming at one group of disks so as to ensure that the created disk snapshots are data of the same accurate time point. As shown in fig. 3, one embodiment of S103 may include the following steps:
s1031: judging whether the number of the disks mounted by the target virtual machine is a single disk or a plurality of disks, and if the number of the disks is a single disk, executing S1032; if there are multiple disks, S1033 is performed.
S1032: and calling a snapshot interface of the storage system to perform snapshot operation on the disk based on the corresponding relation between the disk and the storage system.
S1033: and calling a consistency snapshot interface of the storage system to perform consistency snapshot operation on each disk based on the corresponding relation between the disk and the storage system.
As can be seen from the above, the virtual machine memory snapshot provided in the embodiment of the present invention supports consistent snapshot management, can ensure that snapshot data of multiple disks are consistent, and is suitable for a core service environment with high requirements on data timeliness, data time point accuracy, and service continuity.
In this application, after completing the virtual machine memory snapshot, when data needs to be restored at a certain time, the storage system provides a snapshot rollback interface, and after S103, the method may further include:
s104: and sending a snapshot data recovery request to the cloud platform so that the cloud platform calls a snapshot rollback interface of the storage system to perform snapshot rollback operation on the corresponding storage volume, and thus, the data can be quickly recovered to the data of the created snapshot time point.
It can be understood that, the snapshot operation in S103 may fail due to network, power failure, and the like, and in order to find out that the snapshot fails in time, so as to take corresponding measures quickly, such as taking the snapshot again, or detecting the cause of the snapshot failure and locating the fault, the present application may further include:
s104: if the snapshot file is not detected within the preset time period, the system running log information from the moment when the cloud platform issues the snapshot creation operation instruction of the target virtual machine to the current moment is received, packaged and sent to the target path.
S105: and sending feedback information of snapshot failure to the cloud platform so as to enable the cloud platform to resend the snapshot creation request.
The target path may be a pre-bound client or a certain file of a certain system, which does not affect the implementation of the present application.
It should be noted that, in the present application, there is no strict sequential execution order among the steps, and as long as a logical order is met, the steps may be executed simultaneously or according to a certain preset order, and fig. 1 and fig. 3 are only schematic manners, and do not represent only such an execution order.
