and 102, acquiring the identifier of the primary virtual machine.
The VMware virtual machine is a virtual machine constructed by adopting VMware software, and when the VMware virtual machine is actually applied, a plurality of Windows, DOS and LINUX systems are simultaneously operated on the same computer, so that automatic deployment can be ensured to be simultaneously carried out on the plurality of VMware virtual machines. As shown in fig. 2, it is an architecture diagram of the disaster recovery backup system of the virtual machine.
The primary virtual machine refers to a virtual machine which needs to perform virtual machine resource backup, and the primary virtual machine is one of a plurality of VMware virtual machines deployed in a computer cluster, for example, the virtual machine may be a vcenter. Specifically, the VMware virtual machine is connected through a vSphere WS API, wherein the vSphere WS API is an ESX/ESxi Host and vCenter Server developer interface provided by an official party, the virtual machine configuration information is viewed through the API, and the unique identifier in the data object of the configuration information is determined as the identifier of the main virtual machine.
And step 104, determining one main virtual machine from the multiple VMware virtual machines according to the identification of the main virtual machine.
Specifically, the VMware virtual machine with the identifier consistent with that of the primary virtual machine is determined as the primary virtual machine, and the method can be implemented in a VDDK (virtual disk development kit) manner, and a primary virtual disk storage File (VMDK File) is connected and accessed by using a C/C + + Lib library provided by VDDK, so as to implement backup of data of the primary virtual machine in the subsequent process.

The parameter information of the primary virtual machine refers to parameter information reflecting performance and configuration information of the primary virtual machine, for example, IP, CPU version, network adapter information, disk information, memory information, and the like of the primary virtual machine. The standby virtual machine is a VMware virtual machine for backing up data of the main virtual machine. The target computer is one of the computers in the computer cluster and is used for deploying the standby virtual machine. Specifically, a jni (Java Native interface) technology may be used, a Java local interface may be used to write a virtual machine configuration code in advance, so as to ensure that the code is conveniently transplanted on different platforms, and the parameter information of the main virtual machine is obtained by executing the code.

The backup mode can be determined according to the current backup condition, for example, for the first backup, full backup is adopted, otherwise, incremental backup is adopted, so that repeated backup data does not exist in the backed-up data set, the backup data volume and the backup time are reduced, and the backup efficiency is improved.
And step 110, reading disk block data of the primary virtual machine according to a backup mode.
Specifically, according to the backup mode, disk block data of the primary virtual machine is read, that is, when the backup mode is full backup, all data in the disk of the primary virtual machine is read as disk block data, and when the backup mode is incremental backup, data added or updated in the disk of the primary virtual machine is read as disk block data. As can be understood, in this embodiment, the disk block data of the main virtual machine is read according to the backup mode, so that the disk block data is comprehensively and efficiently read, and the virtual machine backup efficiency is favorably improved.
And step 112, writing the disk block data into the standby virtual machine to obtain a backup data set of the standby virtual machine.
