Referring to fig. 2, fig. 2 is a flowchart illustrating a host backup rebuilding method according to a first embodiment of the present invention.
In a first embodiment, the host backup rebuild method includes the following steps:
and step S10, virtualizing the disk of the source host.
It should be noted that, virtualizing the disk of the source host, that is, virtualizing the disk of the source host and data in the disk, generally virtualizing the disk and data of the source host by using a Virtual disk (Virtual disk) technology, virtualizing a corresponding Virtual disk, where each Virtual disk corresponds to one hard disk of the source host, and data in the Virtual disk is consistent with data in the hard disk corresponding to the source host.
Further, the step S10 specifically includes the following steps:
receiving and storing backup data sent by a source host;
and virtualizing the disk of the source host to generate a virtual disk so as to enable the virtual disk to correspond to the hard disk of the source host and enable the backup data to correspond to the original data of the source host.
It should be understood that the backup data is data of a preset source host needing to be stored, and the virtual disk corresponding to the backup data is virtualized to generate a corresponding virtual disk, so that the virtual disk corresponds to the hard disk of the source host, and the backup data corresponds to the original data of the source host, thereby preparing for subsequent host backup reconstruction.
In a specific implementation, a backup interface of the VmWare virtualization platform is generally used to backup data of a source host on the virtualization platform to a file server, where the file server is a server for storing backup data of other hosts, and the data after each backup may be referred to as a backup point.
Step S20, analyzing the virtualized virtual disk, and acquiring the partition information of the virtual disk.
It can be understood that the partition information of the virtual disk is the storage space distribution type information of each virtual disk, and the storage space distribution information corresponding to the virtual disk can be obtained by analyzing the virtualized virtual disk, so as to prepare for the subsequent mounting operation of the disk partition; generally, a plurality of physical disk groups combined by using a RAID (Redundant array of Independent Drives) technology is referred to as a virtual disk, the virtual disk may be logically divided again, and the divided disks are referred to as logical disks.
In a specific implementation, the disk type and the partition information of each virtual disk may be obtained through analyzing the virtualized virtual disk, where the disk type may be a globally unique partition table (GPT) type, or a Master Boot Record (MBR) type, and of course, other disk types may also be Wie.
And step S30, determining the partition type of each disk partition according to the partition information, and mounting each disk partition according to the partition type.
It should be understood that after the partition information is obtained, the partition type of the disk partition may be determined through analysis of the partition information, that is, the usage of different disk partitions may be determined according to the partition type of the disk partition, and then the partition mount may be performed according to different usage.
Step S40, searching a system boot and a boot configuration file from each mounted disk partition, and determining a primary hot data area according to the system boot and the boot configuration file, where the primary hot data area is a storage area of minimum data required for starting a target operating system.
It can be understood that, by searching each mounted disk partition, corresponding system boot and boot configuration data, that is, corresponding system boot and boot configuration files, can be found, and further, a primary hot data area can be determined according to the system boot and boot configuration files, where the primary hot data area is a storage area of minimum data required for starting a target operating system, that is, a minimum file required for recovering the system.
Step S50, sending the target data in the primary hot data area to a target host, so that the target host performs backup reconstruction after receiving the target data.
It should be noted that the target host is a preset host for restoring and recovering system backup data, generally, the most important data is restored and recovered, the secondary valid data is recovered, and finally other remaining data is recovered, the primary hot data area stores the minimum data required for starting the target operating system, and the target host can reconstruct and recover the target operating system through the target data in the primary hot data area.

acquiring hardware information of a target host, and correcting a current operating system of the target host according to the hardware information;
and sending a preset auxiliary quick reconstruction agent program to the target host, so that the preset auxiliary quick reconstruction agent program is started when the corrected current operating system is started.
It can be understood that the hardware information of the target host is the hardware configuration information of the target host, and generally before the system is built and quickly rebuilt to the target host, an auxiliary program may be run on the target host to collect the hardware information of the target host and send the hardware information of the target host to the file server through network connection; the current operating system of the target host can be corrected through the hardware information, so that the target host can smoothly run the target data to perform system backup, restoration and reconstruction; the preset auxiliary quick reconstruction agent is a preset agent for assisting a quick reconstruction system, and can be generally set to be started along with the system starting, and then can be communicated with a file server through a network to complete the recovery of data except primary hot data.
Further, the step of obtaining the hardware information of the target host and modifying the current operating system of the target host according to the hardware information specifically includes the following steps:
acquiring a system configuration file of the source host and hardware information of a target host;

and modifying the current operating system of the target host according to each driver and the system configuration file.
It should be understood that, after the system configuration file of the source host is a configuration parameter corresponding to a system operation configuration environment of the source host, and the system configuration file of the source host and the hardware information of the target host are acquired, the current operating system may be modified according to the system configuration file, the driver is a driver that is respectively acquired from a preset driver database according to the hardware information and is matched with a disk controller, a network card controller, a mouse controller, a keyboard controller, and a video card controller of the target host, the preset driver database is a preset database that stores various drivers, and generally, the network card may be configured before modification, so that the system may use a network during initialization.
