[0024] According to another aspect of the present invention, a server is provided, the server comprising:

[0025] at least one processor; and

[0039] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0041] Figure 1 A flow chart of a disk data backup method for a virtual machine provided in an embodiment of the present invention, this embodiment is applicable to the situation where disk data to be backed up in a VMware server is backed up to a second server via a first server. The method can be executed by a disk data backup device of the virtual machine, and the disk data backup device of the virtual machine can be implemented in the form of hardware and / or software, and the disk data backup device of the virtual machine can be configured in the server. In this embodiment, the server can be a server that supports VMware virtual machine functions. Also, in this embodiment, the first server, the second server, the third server and the VMware server can all be servers that support virtual machine functions, and the third server and the second server can support virtual machine functions of multiple virtual machine platforms. The VMware server is a cloud management terminal of VMware, such as a server that carries a VMware server. The above-mentioned servers can be heterogeneous servers. Such as Figure 1 As shown, the method includes:

[0042] S101. Receive a disk backup identifier sent by a second server, and send a first instruction to a VMware server.

[0043] The disk backup identifier is obtained by the third server from the VMware server and forwarded to the second server, and the first instruction includes the disk identifier of the disk to be backed up and the disk backup identifier.

[0044] In this embodiment, the first server supports VMware virtual machine functions, and therefore, a read-write virtual machine of VMware for performing read and write operations is provided on the first server. The second server supports virtual machine functions of various platforms, and therefore, a storage virtual machine for performing storage functions is provided on the second server. And, the third server supports virtual machine functions of various platforms, and therefore, a control virtual machine for controlling virtual machines in other servers is provided on the third server. This embodiment is an exemplary explanation based on the working interaction between the virtual machines provided in the above three servers. Therefore, for the convenience of explanation, the following example is taken as an example of the interaction process between the first server, the second server and the third server, but in reality, it is the process of interaction between the virtual machines in the above three servers.

[0045] Specifically, the third server can be used as a server that carries the function of controlling virtual machines, and controls other servers before backup. For example, before the first server receives the disk backup identifier sent by the second server, the third server can control the start of the read-write virtual machine in the first server, and control the initialization of the storage virtual machine of the storage function of the second server. Afterwards, the disk backup identifier of the disk to be backed up is obtained from the service end of the VMware server. After the third server obtains the disk backup identifier, it sends the disk backup identifier to the second server. At this time, the first server can receive the disk backup identifier sent by the second server, and send the first instruction to the VMware server.

[0046] Exemplarily, the initialization content of the storage virtual machine in the second server controlled by the third server may include: the type of backup task, the identifier of the disk to be sent, the number of disks, the size of the disk, and other information.

[0047] S102: Obtain disk data corresponding to the disk backup identifier in the disk to be backed up determined by the VMware server according to the disk identifier.

[0048] Specifically, after the first server sends the first instruction to the VMware server, since the first instruction includes the disk identifier of the disk to be backed up, the VMware server can determine the disk data corresponding to the disk identifier and the disk backup identifier among all the disk data it has according to the disk identifier. And, after the VMware server determines the disk data, it can send the disk data to the first server. And, the first server can receive the disk data of the disk to be backed up fed back by the VMware server.

[0049] Exemplarily, the disk identifier is used to indicate the disk to be backed up, and the disk backup identifier is used to indicate the data of the disk to be backed up that needs to be backed up this time. For example, the VMware server includes disk data of three disks A, B, and C. The disk identifier is used to determine that the disk to be backed up this time is B, and then the disk backup identifier can be used to determine whether the backup is the full data or incremental data in disk B.

[0050] In this embodiment, the first instruction carrying the disk identifier and disk backup identifier of the disk is used to obtain the corresponding disk data from the VMware server, thereby accurately obtaining the disk data of the disk to be backed up and determining whether the backed-up disk data is full data or incremental data based on the disk backup identifier.

[0051] S103: Send the disk data to the second server.

[0052] Specifically, after the first server receives the disk data, the first server may send the disk data to the second server, so that the second server saves the disk data, thereby backing up the disk data of the disk to be backed up.

[0053] In this embodiment, disk data is sent to the second server so that the second server backs up the disk data of the disk to be backed up, which solves the current problem of not being able to support heterogeneous server backup and realizes data transmission and data backup between heterogeneous servers. At the same time, since the first server supports the VMware virtual machine function, the first server directly obtains the disk data of the disk to be backed up in the VMware server and sends it to the second server. The dedicated network used will not cause performance loss, which improves the data reading and writing capabilities. Furthermore, it is determined whether the backed-up disk data is full data or incremental data based on the disk backup identifier, so that after the disk data of the disk to be backed up is backed up for the first time, subsequent data backup only needs to be incremental backup.

[0054] Compared with traditional data backup methods, it has high backup efficiency and saves backup space.

[0055] The disk data backup method of the virtual machine provided by the embodiment of the present invention receives the disk backup identifier sent by the second server, and sends the first instruction to the VMware server; obtains the disk data corresponding to the disk backup identifier in the disk to be backed up determined by the VMware server according to the disk identifier; and sends the disk data to the second server. In the above technical scheme, on the one hand, the first instruction carrying the disk identifier and the disk backup identifier of the disk is used to obtain the corresponding disk data from the VMware server, so as to accurately obtain the disk data of the disk to be backed up, and to determine whether the backed-up disk data is full data or incremental data according to the disk backup identifier. On the other hand, the disk data is sent to the second server so that the second server backs up the disk data of the disk to be backed up, which solves the problem that the backup of heterogeneous servers cannot be supported at present, and realizes the data transmission and data backup between heterogeneous servers. At the same time, since the first server supports the VMware virtual machine function, it is realized that the disk data of the disk to be backed up in the VMware server is directly obtained by the first server, and in the process of sending it to the second server, the dedicated network used will not cause performance loss, thereby improving the data reading and writing capabilities. Furthermore, the disk backup identifier determines whether the backed-up disk data is full data or incremental data, so that after the disk data of the disk to be backed up is backed up for the first time, subsequent data backup only needs incremental backup. Compared with traditional data backup methods, it has high backup efficiency and saves backup space.

[0056] Figure 2 Another flowchart of the method for backing up disk data of a virtual machine provided by an embodiment of the present invention is provided. Based on the above embodiments and feasible examples, this embodiment describes in detail the steps of "after receiving the CBT information sent by the second server" and "after sending the disk data to the second server". Figure 2 As shown, the method includes:

[0057] S201. Receive CBT information sent by the second server.

[0058] The disk backup identifier is the CBT information of the changed data blocks of the disk to be backed up. CBT information is a technology used to implement incremental backup in VMware virtualization environment.

[0059] Specifically, before backing up the data of the disk to be backed up, you can first determine whether the data to be backed up this time is full data or incremental data. Therefore, you can use a third server to first obtain CBT information from the VMware server, and forward the obtained CBT information to the second server. The second server forwards the obtained CBT information to the first server. At this point, the first server receives the CBT information sent by the second server, and can determine whether the disk data of the disk to be backed up that needs to be read during this backup process is a full backup or an incremental backup.

[0060] In this embodiment, since other servers are used to obtain CBT information from the VMware server, it is possible to determine CBT information without relying on the host and without shutting down the virtual machine. At the same time, it also provides support for backing up disk data later without shutting down the virtual machine.

[0061] S202: Send a second instruction to the VMware server.

[0062] The second instruction includes a disk identifier. In this embodiment, the disk identifier includes an identity identifier of the disk to be backed up, and also includes an identifier for obtaining a metadata file (meta file) of the disk to be backed up.

[0063] Specifically, after determining whether the data backed up this time is a full backup or an incremental backup, the first server may send a second instruction to the VMware server.

[0064] S203: Receive the metadata file of the disk to be backed up determined by the VMware server according to the disk identifier.

[0065] The metadata file is a meta file. The meta file is used to store important metadata about the main resource to ensure the consistency and correct management of the resource in the editor and version control system.

[0066] Specifically, after the first server sends the second instruction to the VMware server, the VMware server determines the metadata file of the disk to be backed up according to the disk identifier in the second instruction, and after determination, feeds the metadata file back to the first server. At this point, the first server can receive the metadata file. In addition, the metadata file can be sent to the second server for storage, so as to prepare space for the second server to store the disk data of the disk to be backed up.

[0067] S204: Send a first instruction to the VMware server.

[0068] Specifically, after the first server receives the metadata file, it may send a first instruction to the VMware server.

[0069] S205: Obtain disk data corresponding to the disk backup identifier in the disk to be backed up determined by the VMware server according to the disk identifier.

[0070] Specifically, after receiving the first instruction sent by the first server, the VMware server determines the disk to be backed up according to the disk identifier in the first instruction, and determines the full disk data or incremental disk data to be backed up this time according to the disk backup identifier, that is, the CBT information. After determination, the disk data is sent to the first server, and the first server obtains the disk data.

[0071] S206: Send the disk data to the second server.

[0072] Specifically, after the first server obtains the disk data, the disk data may be sent to the second server so that the second server backs up the disk data.

[0073] At this point, the process of backing up the data on the backup disk is completed. After that, the process of restoring the data on the recovery disk begins.

[0074] S207: Receive the metadata file of the disk to be restored sent by the second server, and send the metadata file of the disk to be restored to the VMware server.

[0075] Specifically, before receiving the metadata file of the disk to be restored sent by the second server, the third server will send a recovery request to the second server. The recovery request is used to indicate the disk number identification information of the disk to be restored that needs to be restored this time. Therefore, after the third server sends the recovery request to the second server, the first server will receive the metadata file of the disk to be restored sent by the second server. And, the first server will send the metadata file to the VMware server.

[0076] S208: Receive the disk data to be restored sent by the second server.

[0077] The disk data to be restored is determined by the second server after receiving the restoration request sent by the third server, according to the number identification information of the restoration disk carried in the restoration request.

[0078] Specifically, after the third server sends a recovery request to the second server, the first server will also receive the disk data to be recovered sent by the second server. That is, the second server will determine the disk data to be recovered of the disk to be recovered based on the serial number identification information of the disk to be recovered carried in the recovery request and based on the metadata information, and send the disk data to be recovered to the first server.

[0079] S209: Send a recovery instruction to the VMware server.

[0080] The recovery instruction includes the disk data to be recovered, so that the VMware server recovers the disk data to be recovered according to the recovery instruction.

[0081] Specifically, after the first server receives the disk data to be restored, it can send a restore instruction to the VMware server. The restore instruction includes the disk data to be restored. Therefore, after the VMware server receives the restore instruction, it can restore the disk data of the disk to be restored according to the disk data to be restored in the restore instruction.

[0082] In this embodiment, multiple servers are used to interact with the VMware server to implement the recovery process of the backup data stored in the second server, and the backup and recovery of data between heterogeneous servers is implemented without shutting down.

[0083] Figure 3 This is another flow chart of the method for backing up disk data of a virtual machine provided by an embodiment of the present invention. This embodiment uses VMware server as the execution subject and describes the interaction process between VMware server and other three servers. Figure 3 As shown, the method includes:

[0084] S301. Send a disk backup identifier to a third server.

[0085] Specifically, after receiving the acquisition instruction from the third server, a disk backup identifier is sent to the third server, wherein the disk backup identifier is the CBT information of the changed data block of the disk to be backed up.

[0086] S302: Receive a first instruction sent by a first server.

[0087] The first server supports VMware virtual machine function, the first instruction includes a disk identifier and a disk backup identifier of the disk to be backed up, and the disk backup identifier is obtained by the second server from the third server and forwarded to the first server.

[0088] Before receiving the first instruction sent by the first server, the method further includes:

[0089] (1) Receive a second instruction sent by the first server.

[0090] The second instruction includes a disk identifier.

[0091] Specifically, after sending the CBT information to the third server, the first server will send the second instruction to the VMware server, so the VMware server can receive the second instruction.

[0092] (2) The metadata file of the disk to be backed up is determined according to the disk identifier.

[0093] Specifically, the VMware server determines the metadata file of the disk to be backed up according to the disk identifier in the second instruction.

[0094] (3) Sending the metadata file of the disk to be backed up to the first server.

[0095] Specifically, after the VMware server determines the metadata file of the disk to be backed up, it sends the metadata file of the disk to be backed up to the first server.

[0096] And, after sending the metadata file of the disk to be backed up to the first server, the first server will send a first instruction. At this time, the VMware server can receive the first instruction.

[0097] S303: Determine the disk data corresponding to the disk backup identifier in the disk to be backed up according to the disk identifier.

[0098] Specifically, since the VMware server contains all the disk data and other data, in order to determine the disk data of the disk to be backed up from all the disk data, the disk to be backed up can be determined according to the disk identifier, and the full disk data or incremental disk data in the disk data of the disk to be backed up can be determined according to the disk backup identifier.

[0099] S304: Send the disk data to the first server, so that the first server sends the disk data to the second server.

[0100] Specifically, after determining the disk data, the VMware server may send the disk data to the first server, so that the first server sends the disk data to the second server, thereby implementing backup of the disk data.

[0101] Optionally, after sending the disk data to the first server, the method further includes:

[0102] (1) Receive a recovery instruction sent by the first server.

[0103] The recovery instruction includes the disk data to be recovered, and the disk data to be recovered is determined by the second server according to the number identification information of the recovery disk carried in the recovery request after receiving the recovery request sent by the third server.

[0104] Before receiving the recovery instruction sent by the first server, the method further includes:

[0105] Receive the metadata file of the disk to be restored sent by the first server.

[0106] The metadata file of the disk to be restored is sent by the second server to the first server.

[0107] Specifically, before receiving the recovery instruction sent by the first server, the second server will receive the recovery request from the third server, and the second server will send the metadata file of the disk to be recovered to the first server according to the recovery request. At this time, the first server sends the received metadata file to the VMware server. The VMware server can receive the metadata file of the disk to be recovered.

[0108] Specifically, when the first server obtains the disk data to be restored of the disk to be restored from the second server, the first server will send a restoration instruction to the VMware server. At this time, the VMware server can receive the restoration instruction sent by the first server.

[0109] (2) Restore the disk data to be restored according to the recovery instructions.

[0110] Specifically, according to the recovery instruction, the VMware server can recover the disk data of the disk to be recovered.

[0111] After introducing the disk data backup method of a virtual machine provided by an embodiment of the present invention, in order to make the method provided by the present invention clearer, a specific embodiment is provided here for detailed description. Figure 4 As shown, Figure 4 This is an example diagram of an interactive method for backing up disk data of a virtual machine provided by an embodiment of the present invention. Figure 4 In the example, the system is first divided into a third server, a first server, a VMware server and a second server. A control virtual machine is running in the third server, which is used to control the operation of virtual machines in other servers. The platform of this virtual machine is a virtual machine of any platform. A read-write virtual machine is running in the first server, which is used to read and write disk data and related data. The platform of this virtual machine is the VMware platform. The VMware server is a server on the VMware service side, which is used to manage the operation and storage data of all virtual machines on the VMware platform. A storage virtual machine is running in the second server, which is used to store disk data to be backed up. The platform of this virtual machine is a virtual machine of any platform.

[0112] Specifically, the control virtual machine in the third server sends a startup command to the read-write virtual machine in the first server to start the read-write virtual machine. Also, the control virtual machine in the third server sends an initialization command to the storage virtual machine in the second server to enable the storage virtual machine to determine the initialization information, such as the type of backup task, the disk identifier to be sent, the number of disks, the disk size, and other information, and to prepare to receive disk data. Afterwards, the third server sends a CBT information acquisition request to the VMware server, and the VMware server returns the CBT information to the control virtual machine of the third server. The control virtual machine of the third server sends the received CBT information to the storage virtual machine of the second server, and forwards it to the read-write virtual machine of the first server for reading and writing. At this time, the read-write virtual machine of the first server uses the interface provided by the VMware server according to the CBT information to send a connection request to the VMware server and send a second instruction. The VMware server determines the meta file of the disk to be backed up according to the disk identifier in the second instruction, and returns the meta file of the disk to be backed up to the read-write virtual machine of the first server. The read-write virtual machine of the first server sends the meta file of the disk to be backed up to the storage virtual machine of the second server, and the storage virtual machine of the second server backs up the meta file. And, the read-write virtual machine of the first server sends a first instruction to the VMware server, and the VMware server determines the disk to be backed up according to the disk identifier in the first instruction, and determines the full or incremental disk data of the disk to be backed up according to the CBT information, and returns the disk data to be backed up to the read-write virtual machine of the first server. The read-write virtual machine of the first server sends the disk data to be backed up to the storage virtual machine of the second server, so that the storage virtual machine of the second server backs up the disk data. At this point, the disk data of the virtual machine is backed up.

[0113] If it is necessary to restore the disk data that has been backed up, the control virtual machine of the third server sends a recovery request to the storage virtual machine of the second server. The storage virtual machine of the second server determines the meta file of the disk to be restored based on the number identifier of the disk to be restored in the recovery request, and sends it to the read-write virtual machine of the first server, so that the read-write virtual machine of the first server sends the meta file to be restored to the VMware server. In addition, the storage virtual machine of the second server sends the disk data to be restored to the read-write virtual machine of the first server, and the read-write virtual machine of the first server sends it to the VMware server, thereby realizing the recovery of the backed-up disk data.

[0114] The beneficial effect of the above method is that it realizes the backup and recovery of VMware virtual machines, which is suitable for scenarios with agents. In addition, the first backup is a full backup, and each subsequent backup is an incremental backup. The full backup and incremental backup processes are consistent. After the full backup, a small amount of data that has changed can be backed up incrementally to obtain a full backup, which is more efficient than traditional backup and saves space. The backed-up file is consistent with the original virtual machine file format and can be used directly to mount the virtual machine. The virtual machine can be mounted and used in a short time. Finally, the backup of this method does not depend on the host, and the backup and recovery do not require shutdown operations, which does not affect the normal operation of the virtual machine. It is compatible with multiple versions and has a fast backup and recovery speed.
