Abstract

The invention discloses a method and a device for backing up a Unix-like operating system at multiple time points. The method comprises the following steps of packing increment files into a plurality of increment image files corresponding to different time points according to time sequence; when the Unix-like operating system is started, performing merged running on a basic image file and one or more increment image files in the increment image files according to time sequence to establish new increment files. By the method and the device, different backups can be selected for running the operating system according to different time points, the modification made by the system can be saved, the backup and recovery at multiple state points can be implemented according to time, bidirectional recovery can be realized, and the system can be recovered to a front time point, and can also be recovered from the front time point to a back time point.

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 at multiple time points 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 ...
