Abstract

The present invention provides an operating system backup and restore method, which includes: obtaining the data partition information on the source disk of the Linux system; mounting the data partition information to the Regeneron system directory; executing the tar command to package the source disk data file; save the data partition information; read the data partition information; partition the target disk according to the data partition information; mount the partition of the target disk; execute the tar command to decompress the source disk The data file on the above is to the target disk; judge the grub version of the Linux system according to the decompressed data file; install the correct grub version of the Linux system. The invention can remove the restriction that the capacity of the target disk must be greater than or equal to the capacity of the source disk in the regeneration dragon, and can select the grub configuration to correctly guide the Linux system.

Description

technical field [0001] The invention relates to the technical field of computer science, in particular to an operating system backup restoration method. Background technique [0002] With the continuous development of the Linux operating system, the Linux operating system has been used more and more widely, and it is an important technology to backup and restore the Linux system. The backup and restore tools that come with the Linux system include commands such as dd, tar, cpio, and dump. These commands are generally operated on the command line and are suitable for system administrators and developers. For users who are accustomed to operating Windows and new to Linux, Using these backup restore tools is difficult. [0003] In the prior art, Zaishenglong software is a small but fully functional system cloning tool, which can be used for the backup and restore operation of the Linux system, and provides a relatively friendly operation interface, and supports Chinese display...
