[0026] A cloud computing platform is a platform that can provide computing and storage services. It is usually composed of a cloud server cluster. With the rapid development of technology, cloud computing has brought convenient services to daily life and is widely used in various fields.

[0027] In a cloud computing environment, user services run in virtual machines. However, the instability of the cloud computing environment affects the stability and reliability of computing resource supply. As a result, sudden virtual machine failures can lead to problems such as user service interruptions. Therefore, in order to protect the normal operation of user services, virtual machines are backed up.

[0028] In the related art, a data backup thread is usually run in a virtual machine, and the data to be backed up of the virtual machine is read by the data backup thread, and the data to be backed up is sent to a backup storage device for storage.

[0029] In the process of realizing the concept of the present application, the inventors discovered that in the related art backup method of running a data backup thread in a virtual machine, the running of the backup thread consumes the running resources of the virtual machine, resulting in a reduction in the running performance of the virtual machine.

[0030] In order to solve the technical problems existing in the related technology, an embodiment of the present application provides a virtual machine backup method, which is applied to a control server, and the control server establishes a connection with a first virtual machine; the virtual machine backup method adopts: receiving a virtual machine backup request, the virtual machine backup request includes a virtual machine identifier of the first virtual machine; determining a first storage device corresponding to the first virtual machine based on the virtual machine identifier, the first storage device is used to store the first data to be backed up of the first virtual machine; determining a second storage device corresponding to the first storage device; and copying the first data to be backed up from the first storage device to the second storage device. The virtual machine backup method provided in the embodiment of the present application is executed by the control server, and the backup data is directly copied and synchronized at the underlying storage device level without occupying the memory of the virtual machine, so that the operating performance of the virtual machine is not affected by the data backup process.

[0031] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0032] Figure 1 schematically shows a flowchart of a virtual machine backup method provided by an embodiment of the present application, which is applied to a control server to establish a connection with a first virtual machine; as shown in Figure 1, the virtual machine backup method may include the following steps: 101, receiving a virtual machine backup request, the virtual machine backup request including a virtual machine identifier of the first virtual machine; 102, determining a first storage device corresponding to the first virtual machine based on the virtual machine identifier, the first storage device being used to store first data to be backed up of the first virtual machine; 103, determining a second storage device corresponding to the first storage device; 104, copying the first data to be backed up from the first storage device to the second storage device.

[0033] In an embodiment of the present application, a virtual machine backup request can be triggered by a user. There are various ways for a user to trigger a virtual machine backup request. In one embodiment, the user triggers the request through the virtual machine operating system. There are various ways to trigger the request, such as by clicking a data backup control on the operating system, by controlling a smart wearable device, or by voice, gesture, etc., which are not limited here.

[0034] In an embodiment of the present application, the virtual machine backup request can be generated immediately after being triggered by the user, or it can be generated according to the backup time set by the user. For example, if the user chooses to back up data at 8 pm, the virtual machine backup request is generated at 8 pm, or the backup request is generated according to the periodic backup time set by the user. For example, the user sets a backup once a day, and each backup time is 3 am. The time of the first backup cycle set by the user is 3 am on March 1, 2023, then the virtual machine backup request is generated at 3 am on March 1, 2023.

[0035] According to an embodiment of the present application, when triggering a virtual machine backup request, the user may trigger the virtual machine backup request on the first virtual machine that needs to be backed up, or may trigger the backup request for the first virtual machine in other virtual machines.

[0036] According to an embodiment of the present application, after the user triggers a virtual machine backup request, the virtual machine identifier of the first virtual machine to be backed up may be written into the virtual machine backup request, and then the virtual machine backup request may be sent to the control server.

[0037] According to an embodiment of the present application, after receiving the virtual machine backup request, the control server can parse the virtual machine backup request and obtain a virtual machine identifier to determine the first virtual machine that needs to be backed up.

[0038] According to an embodiment of the present application, the first storage device can be implemented as a cloud storage device or a local storage device, and the first storage device can establish a connection with the control server to receive operation instructions sent by the control server.

[0039] According to an embodiment of the present application, the first storage device may store data in the form of block storage, but is not limited thereto, and may also store data in the form of object storage, file storage, etc.

[0040] According to an embodiment of the present application, the first storage device may be a system disk of the first virtual machine, which may be used to store the operating system, application programs and configuration files of the first virtual machine, as well as data generated during operation or required for operation of the first virtual machine.

[0041] According to an embodiment of the present application, the correspondence between the first virtual machine and the first storage device can be pre-registered to the control server. Thus, after receiving the virtual machine backup request, the control server can determine the first storage device corresponding to the first virtual machine based on the pre-stored correspondence, thereby backing up the first data to be backed up stored in the first storage device.

[0042] According to an embodiment of the present application, when backing up the first data to be backed up, it can be implemented by synchronizing the second data to be backed up to the second storage device.

[0043] According to an embodiment of the present application, the second storage device can be a storage device that has pre-created a master-slave relationship with the first storage device. For example, the first storage device is the master storage device, which reads and writes data as the system disk of the first virtual machine, and the second storage device is the slave storage device of the first storage device, which is responsible for receiving and storing data synchronized from the first storage device.

[0044] According to an embodiment of the present application, when copying the first data to be backed up from the first storage device to the second storage device, it can be specifically implemented as follows: copying the first data to be backed up to obtain first copy data; and storing the first copy data in the second storage device.

[0045] In the implementation process of the virtual machine backup method provided in the embodiment of the present application, it is only necessary to use the first virtual machine to generate and send a virtual machine backup request, and then the control server side manages and controls the virtual machine backup, so that the backup process can be carried out at the storage device level without occupying the operating resources of the first virtual machine.

[0046] According to an embodiment of the present application, copying the first data to be backed up from the first storage device to the second storage device can be specifically implemented as follows: backing up the first data to be backed up to obtain snapshot data; and sending the snapshot data to the second storage device.

[0047] According to an embodiment of the present application, when backing up the first data to be backed up, a snapshot of the entire first data to be backed up stored in the first storage device can be taken to obtain snapshot data. The snapshot data can be a record of the data state of the first storage device at a certain point in time. The snapshot data can only record data that has changed on the first storage device. This can be achieved by creating a pointer or metadata.

[0048] According to an embodiment of the present application, after sending the snapshot data to the second storage device, the virtual machine backup method also includes: determining whether the first storage device meets the first backup condition; when the first storage device meets the first backup condition, determining the incremental data of the first storage device; backing up the incremental data to obtain incremental snapshot data; and sending the incremental snapshot data to the second storage device.

[0049] According to an embodiment of the present application, the first backup condition may include, for example, a time condition and a data volume condition. The time condition may include, for example, whether the time since the last backup is greater than a preset time period or whether a specified time point has been reached; the data volume condition may include, for example, whether the incremental data reaches a preset data volume.

[0050] According to an embodiment of the present application, after backing up the full amount of data stored in the first storage device, i.e., the first data to be backed up, the first storage device can be continuously backed up. For example, the incremental data of the first storage device can be backed up. For example, the full amount of data stored in the first storage device includes data A, data B, and data C. After data A, data B, and data C are backed up, data D is written to the first storage device. In this case, data D can be the incremental data of the first storage device. On this basis, data D can be backed up.

[0051] According to an embodiment of the present application, when performing incremental data backup on a first storage device, a snapshot of the incremental data can be taken to obtain incremental snapshot data, and the incremental snapshot data can be stored in a second storage device to ensure data consistency between the second storage device and the first storage device.

[0052] According to an embodiment of the present application, after receiving a virtual machine backup request, the virtual machine backup method also includes: creating a second storage device in response to the virtual machine backup request; creating a first backup relationship between the first storage device and the second storage device; determining the second storage device corresponding to the first storage device includes: determining the second storage device corresponding to the first storage device based on the first backup relationship.

[0053] According to an embodiment of the present application, a virtual machine backup request may include backup requirement information, and the backup requirement information may include, for example, storage space requirements, storage performance requirements, storage type requirements, and other information.

[0054] According to an embodiment of the present application, after receiving a virtual machine backup request, the virtual machine backup request can be parsed to obtain backup requirement information, and then a second storage device that can meet the backup requirements of the first virtual machine is created according to the backup requirement information.

[0055] According to an embodiment of the present application, after the second storage device is created and generated, the access interface of the second storage device may be exposed to the first storage device, so that the first storage device can transmit data using the access interface.

[0056] According to an embodiment of the present application, the first backup relationship is used to indicate the backup direction from the first storage device to the second storage device. By establishing the first backup relationship, a master-slave relationship between the first storage device and the second storage device can be determined. The first storage device is the master storage device, which reads and writes data as the system disk of the first virtual machine, and the second storage device is the slave storage device of the first storage device, responsible for receiving and storing data synchronized from the first storage device.

[0057] According to an embodiment of the present application, the virtual machine backup method also includes: receiving a backup relationship switching instruction; pausing the synchronization process of the backup data in response to the backup relationship switching instruction; switching the first backup relationship to a second backup relationship, the second backup relationship being used to indicate the backup direction from the second storage device to the first storage device; in response to the backup relationship switching to the second backup relationship, copying the second data to be backed up stored in the second storage device to the first storage device.

[0058] According to an embodiment of the present application, switching the backup relationship involves switching the master-slave relationship between the first storage device and the second storage device, switching the first storage device from a master storage device to a slave storage device, and switching the second storage device from a slave storage device to a master storage device. In the second backup relationship, the second storage device serves as the master storage device, reading and writing data as the system disk of the first virtual machine, while the first storage device serves as the slave storage device of the second storage device, responsible for receiving and storing data synchronized from the second storage device.

[0059] According to an embodiment of the present application, pausing the synchronization process of the backup data can be achieved by controlling the server to send a pause instruction to the first storage device and the second storage device respectively.

[0060] According to an embodiment of the present application, after the pause instruction reaches the first storage device and the second storage device, the master-slave relationship between the first storage device and the second storage device will be suspended, and the data synchronization process between the first storage device and the second storage device will be suspended.

[0061] According to an embodiment of the present application, the synchronization process of pausing data between the first storage device and the second storage device may refer to the suspension of the passing process of the incremental data generated after the pause instruction reaches the first storage device and the second storage device, and the data synchronization process that has been started before the pause instruction reaches the first storage device and the second storage device will continue to be executed.

[0062] According to an embodiment of the present application, the virtual machine backup method also includes: receiving a backup configuration instruction; pausing the synchronization process of the backup data in response to the backup configuration instruction; performing corresponding configuration operations on the synchronization process of the backup data based on the backup configuration instruction; and starting the synchronization process of the backup data in response to completion of the configuration operation.

[0063] According to an embodiment of the present application, the backup configuration instruction may be used to modify the RPO (Recovery Point Object), bandwidth, etc. during the data synchronization process.

[0064] According to the embodiments of the present application, when modifying configurations such as RPO and bandwidth, it is usually necessary to first stop the synchronization relationship to ensure data integrity and consistency. This is because during the synchronization process, there will be a certain amount of data delay between the first storage device and the second storage device. If the RPO and bandwidth configurations of the synchronization relationship are modified during this process, data may be lost or incomplete during transmission, thereby affecting the normal operation of the application and data integrity. Therefore, it is possible to stop the synchronization relationship first and then modify the relevant configurations.

[0065] According to an embodiment of the present application, receiving a backup relationship switching instruction may be specifically implemented as: receiving a backup relationship switching instruction sent by a user.

[0066] In an embodiment of the present application, the backup relationship switching instruction can be triggered by the user. There are multiple ways for the user to trigger the backup relationship switching instruction. In one embodiment, the user triggers it through the virtual machine operating system. There are multiple ways to trigger it, such as by the user clicking the relationship switching control of the operating system, by the control of a smart wearable device, or by voice, gesture, etc., which are not limited here.

[0067] According to another embodiment of the present application, receiving the backup relationship switching instruction may be specifically implemented as: receiving the backup relationship switching instruction triggered after a failure of the first storage device is detected.

[0068] According to an embodiment of the present application, after the first storage device fails, data writing and reading functions of the first storage device may become abnormal. At this time, the failed first storage device may cause the service running in the first virtual machine to become abnormal.

[0069] According to an embodiment of the present application, the first virtual machine can detect the operating status of the first storage device and generate a backup relationship switching instruction after detecting a failure of the first storage device.

[0070] According to an embodiment of the present application, after copying the first data to be backed up from the first storage device to the second storage device, the virtual machine backup method also includes: in the event of a failure of the first storage device, terminating the correspondence between the first virtual machine and the first storage device; and creating a correspondence between the first virtual machine and the second storage device.

[0071] According to an embodiment of the present application, after the first data to be backed up is copied from the first storage device to the second storage device, data consistency between the first storage device and the second storage device can be guaranteed.

[0072] According to an embodiment of the present application, a failure of the first storage device may cause abnormalities in the data writing and reading functions of the first storage device. In this case, the failed first storage device may cause abnormalities in the services running in the first virtual machine. Because the first storage device and the second storage device have data consistency, the second storage device can be directly configured as the system disk of the first virtual machine, and the data of the second storage device can be used to support the operation of the first virtual machine.

[0073] According to an embodiment of the present application, in response to a virtual machine backup request, creating a second storage device can be specifically implemented as follows: in response to the virtual machine backup request, determining the first area where the first storage device is located; and creating a second storage device in a second area different from the first area.

[0074] According to an embodiment of the present application, the first area and the second area may refer to different geographical areas, that is, the first storage device and the second storage device may operate in computer rooms located in different geographical areas.

[0075] According to an embodiment of the present application, by creating a second storage device in a second area different from the first area, the risk of simultaneous failure of the first storage device and the second storage device can be reduced.

[0076] FIG2 schematically shows a diagram of a virtual machine backup method provided in an embodiment of the present application.

[0077] In FIG. 2 , 201 may represent a first area, 202 may represent a second area, 203 may represent a control server, 204 may represent a first virtual machine, 2041 may represent a first storage device corresponding to the first virtual machine 204 , and 205 may be a second storage device.

[0078] As shown in FIG2 , the first storage device 2041 is deployed in the first area, and the second storage device 205 is deployed in the second area.

[0079] The first virtual machine 204 may send a virtual machine backup request to the control server 203. After receiving the virtual machine backup request, the control server 203 may determine the first storage device 2041 corresponding to the first virtual machine 204 and the second storage device 205 corresponding to the first storage device 2041.

[0080] Then, the control server 203 may instruct the first storage device 2031 to take a snapshot of the first data to be backed up stored therein, generate first snapshot data, and then back up the first snapshot data to the second storage device 205 .

[0081] According to an embodiment of the present application, the virtual machine backup method also includes: receiving a backup relationship termination instruction; pausing the synchronization process of the backup data in response to the backup relationship termination instruction; and cutting off the first backup relationship to terminate the backup data synchronization process from the first storage device to the second storage device.

[0082] FIG3 schematically shows a schematic diagram of backup control provided in an embodiment of the present application.

[0083] During the initialization phase, the control server can create a first storage device and a second storage device, and establish a synchronization pair relationship between the first storage device and the second storage device. This synchronization pair relationship allows the first storage device and the second storage device to synchronize data with each other. For example, the synchronization pair can be a master-slave synchronization pair relationship, with the first storage device set as the master storage device and the second storage device set as the slave storage device.

[0084] After the synchronization pair relationship is successfully created, the synchronization pair relationship can be activated by the control server. After activation, the synchronization pair relationship can be in an active state, that is, data synchronization can be performed.

[0085] During the data synchronization process, abnormal events may occur. For example, an abnormal event may occur when the first storage device fails. In this case, the data backup is in an abnormal state due to the failure of the first storage device. In this case, the synchronization relationship can be switched, that is, the first storage device is switched to the slave storage device and the second storage device is switched to the master storage device.

[0086] During the data synchronization process, the synchronization pair relationship can be paused, that is, the data synchronization process can be paused. When data synchronization is paused, synchronization configuration operations, master-slave relationship switching operations, etc. can be performed. Moreover, when the synchronization configuration operations and master-slave relationship switching operations are completed, the synchronization pair relationship can be switched to the active state to continue the data synchronization process.

[0087] When the synchronization pair relationship is suspended or an abnormal event occurs, the control server can delete the first storage device, the second storage device or the synchronization relationship.

[0088] Through FIG3 above, the embodiment of the present application proposes a data backup control method, so that the data backup can cope with possible abnormal situations and improve the efficiency of data backup.

[0089] An embodiment of the present application also provides a virtual machine backup method, which is applied to a control server, and the control server establishes a connection with a first virtual machine; the method includes: receiving a virtual machine backup request, the virtual machine backup request including a virtual machine identifier of the first virtual machine; determining a first storage device corresponding to the first virtual machine based on the virtual machine identifier, the first storage device being used to store first financial data to be backed up of the first virtual machine; determining a second storage device corresponding to the first storage device; and copying the first financial data to be backed up from the first storage device to the second storage device.
