Problems solved by technology

However, the operating system started by the boot image file can be modified during operation, but the modified content is not saved after the system exits, so that when the user uses the image file to start the operating system next time, the previous modification will be lost, and the user will also lose the modification. Inability to make backups of the operating system in order to preserve modifications

Abstract

The invention discloses an image file start-based Unix-like operating system backup method and an image file start-based Unix-like operating system backup device. The method comprises the following steps of packing an increment file into an increment image file, and deleting the increment file; when the Unix-like operating system is started, carrying out merged running on a base image file and the increment image file and creating a new increment file. By the image file start-based Unix-like operating system backup method and the image file start-based Unix-like operating system backup device, the backup of the Unix-like operating system is realized through the increment image file, the backup process of the operating system is greatly simplified and a simple method is provided for implementing instant and quick one-key reset.

Description

technical field [0001] The invention relates to the technical field of Unix-like operating systems, in particular to a method and device for backing up a Unix-like operating system started based on an image file. Background technique [0002] Image file, also known as image file (image), is a file that combines data and programs. After format conversion, the source data is stored on the hard disk as a file that is exactly the same as the content of the destination CD. This file can be It is engraved into the disc in a one-to-one correspondence. For example, the image file is a complete copy file on the CD, including all the information on the CD, and requires special virtual CD-ROM software to load this image file and read it, which completely simulates the characteristics of reading CD files, for example, in this respect The popular software includes Alcohol, Deam Tools, etc. Before making an image file, do data reorganization and disk scanning on the hard disk. Since the...
