The proxy server 106 may also be implemented by a virtual machine.
In one embodiment, as shown in fig. 2, a virtual machine backup method is provided, which is described by taking the method as an example applied to the backup control server 104 in fig. 1, and includes the following steps:
s210, acquiring a virtual machine backup request, acquiring the position information of the VMware virtual machine to be backed up according to the virtual machine backup request, and searching the proxy server according to the position information.
Specifically, the backup control server 104 may operate on an ARM platform, and the virtual machine backup request refers to a request used for backing up a target VMware virtual machine, where the request specifically includes location information of the VMware virtual machine to be backed up. The location information specifically includes location information of a location of a host of the VMware virtual machine to be backed up, and location information of a location of a computing resource of the VMware virtual machine to be backed up. The proxy server refers to a server that needs to be controlled in the backup process, and in one embodiment, the proxy server may specifically be a virtual machine running under the X86 platform.
Specifically, the backup control server may receive a virtual machine backup request, then obtain location information of the VMware virtual machine to be backed up according to the virtual machine backup request, and determine an optimal proxy server in the virtual machine backup process from a preset proxy server list according to the location information.
And S230, sending a snapshot creating request to the proxy server, wherein the snapshot creating request is used for requesting the proxy server to call a VMware SDK API to create snapshot file data of the VMware virtual machine to be backed up.
The snapshot specifically refers to a VMware snapshot, and the disk "snapshot" is a copy of a disk file of the virtual machine at a certain point in time. A system crash or system exception may be used to maintain disk file systems and system storage using a restore to snapshot. The VMware SDK refers to a software toolkit used in the VMware development process, and the VMware SDK API refers to an interface of the VMware SDK.
The backup control server can send a snapshot creation request to the proxy server of the X86 platform, and after receiving the snapshot creation request, the proxy server can call the VMware SDK API to create snapshot file data of the VMware virtual machine to be backed up. After the snapshot file data is created, the proxy server feeds back a snapshot creation success message to the backup controller.

The target snapshot data refers to snapshot file data needed in the backup process of the virtual machine. And the snapshot acquisition instruction comprises relevant information such as offset and length of the target snapshot data in the snapshot file data. The snapshot file data contains the disk file data of the virtual machine in each period. And in the virtual machine backup process, only the virtual machine at the specified time point needs to be backed up, so that after the backup file metadata is obtained, the snapshot obtaining instruction can be sent to the proxy server, and after the proxy server receives the snapshot obtaining instruction, the virtual machine snapshot data with the specified offset and length is read from the snapshot file data to serve as the target snapshot data. And then transmitted back to the backup control server in a fixed binary message format.
And S290, after receiving the target snapshot data, backing up the VMware virtual machine to be backed up according to the target snapshot data and the backup file metadata.
After receiving the target snapshot data fed back by the proxy server, the backup control server writes the target snapshot data into the designated position of the local backup file, then checks whether the backup is completely completed or not, if not, returns to the step of sending a snapshot obtaining instruction to the proxy server, wherein the snapshot obtaining instruction is used for obtaining the target snapshot data in the snapshot file data, obtains the required target snapshot data, and knows that all the required target snapshot data are obtained. The backup of the VMware virtual machine to be backed up can be completed according to the target snapshot data and the backup file metadata.
Further, after the backup is completed, the backup control server notifies the proxy server that the backup process is finished; after receiving the request for finishing the backup process, the proxy server executes resource cleaning operation locally, including closing snapshot handles, releasing virtual machine locks, deleting backup snapshots and the like, and then informs the backup control server that all resources are cleaned; and the backup control server receives the resource cleaning completion message, then releases the scheduling resources of the local virtual machine, and completely ends the virtual machine backup process.
According to the virtual machine backup method, the virtual machine backup request is obtained, the position information of the VMware virtual machine to be backed up is obtained according to the virtual machine backup request, and the proxy server is searched according to the position information; sending a snapshot creating request to a proxy server, wherein the snapshot creating request is used for requesting the proxy server to call a VMware SDK API (software development kit) to create snapshot file data of a VMware virtual machine to be backed up; when a snapshot creation success message fed back by the proxy server is received, obtaining backup file metadata; sending a snapshot obtaining instruction to a proxy server, wherein the snapshot obtaining instruction is used for obtaining target snapshot data in snapshot file data; and after receiving the target snapshot data, backing up the VMware virtual machine to be backed up according to the target snapshot data and the backup file metadata. According to the method and the system, the proxy server is requested to create the snapshot file of the VMware virtual machine through the snapshot creating request, the snapshot file of the VMware virtual machine is obtained through the snapshot obtaining instruction, and then the virtual machine backup is carried out, so that the backup process of the VMware virtual machine is not limited on an X86 platform, and the expansibility of the backup process of the VMware virtual machine can be effectively improved.

Specifically, the available server specifically refers to other virtual machines installed under the host machine where the VMware virtual machine to be backed up is located, except the VMware virtual machine to be backed up. Other virtual machines under the host machine where the virtual machine is located can be selected as proxy servers to participate in the backup of the virtual machine. Specifically, the host may include a plurality of available proxy servers, and the proxy control server may read load information of the available proxy servers, and then, based on a load balancing manner, may promote an optimal available proxy server as a proxy server in the backup process. And selecting a proper proxy server according to the load data, so that the working efficiency of the proxy server can be effectively improved, and further the working efficiency of the virtual machine in the backup process is improved.
