Embodiment Construction
[0049] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0050]The solutions of the embodiments of the present invention are mainly as follows: the present invention virtualizes the disk of the source host; analyzes the virtualized virtual disk to obtain partition information of the virtual disk; determines the partition information of each disk partition according to the partition information Partition type, and mount each disk partition according to the partition type; search the system guide and boot configuration file from the mounted disk partitions, and determine the first-level hot data according to the system guide and the boot configuration file The first-level hot data area is the storage area with the least data required to start the target operating system; the target data of the first-level hot data area is sent to the target host, so that the target host ...

The invention discloses a host backup and reconstruction method, device, server and storage medium, by virtualizing the disk of the source host; analyzing the virtualized virtual disk to obtain partition information of the virtual disk; determining each disk according to the partition information The partition type of the partition, and mount each disk partition according to the partition type; search the system boot device and boot configuration file from each mounted disk partition, and determine the first-level hot data area according to the system boot device and boot configuration file; Send the target data in the first-level hot data area to the target host, so that the target host can perform backup and reconstruction after receiving the target data. Because the correct boot configuration information is determined, the data can be quickly restored on different hosts, and the host system can be quickly restored. Reconstruction improves the speed and efficiency of data backup and reconstruction, and saves the time for host data backup and reconstruction.
Description
technical field [0001] The present invention relates to the field of data backup, in particular to a host backup and reconstruction method, device, server and storage medium. Background technique [0002] There are generally two ways to back up the host operating system and data. One is to install an agent agent program in the host system, and the host operating system and data are backed up through the agent program. This is called agent backup, and the other is to not install it. The agent program, and the backup interface of the virtualization platform and the backup interface of the storage server are used to complete the backup of the host operating system and data. This is called non-agent backup; however, because the non-agent backup does not have an agent program to obtain the information of the backup host when it is running , for example: the system type of the backup host, the boot program of the system, the relationship between the structure of the disk and the l...
