Embodiment 1

[0075] Please refer to Figure 2 to Figure 4 , this embodiment provides an operating system backup and restore method based on stored sector data, which can not only meet daily needs and recover effectively used sector data; more importantly, it can also achieve recovery through backup when the system is damaged The master boot record sector data (MBR) implements system recovery.

[0076] When the computer starts and completes the self-test, it first looks for the MBR of the disk and reads the boot record in it, and then gives it control over the system. If the MBR is damaged, all subsequent work cannot continue. Therefore, if only the effectively used disk data is backed up according to the traditional method, once the MBR is damaged, the system still cannot be started even after the effectively used disk data is successfully restored. This embodiment has solved the above problems very well, as image 3 As shown, the specific method may include the following steps:

[007...

Embodiment 2

[0119] This embodiment corresponds to Embodiment 1, and provides an operating system backup and restore system based on storage sector data, including a first computer storage medium and a second computer storage medium; the second computer storage medium is the one in Embodiment 1 Self-boot restore system.

[0120] Specifically, the first computer storage medium has a first computer program stored thereon, and when the first computer program is executed by a processor, it can implement all the steps included in "1. Backup process" in the first embodiment above;

[0121] The second computer storage medium has a second computer program stored thereon, that is, the self-boot restoration program described in Embodiment 1. When the self-boot restoration program is executed by a processor, it can realize "two, Backup and restore process" contains all the steps.

Embodiment 3

[0123] Please refer to Figure 5 to Figure 7 , this embodiment corresponds to Embodiment 1 and Embodiment 2, and provides a specific application scenario, based on the disk data that has been backed up, to describe the restoration process in detail:

[0124] 1. If Figure 5 Shown is the first sector information of the backup data read according to the starting position recorded in the backup record information. It can be seen from the figure that the first three bytes 30 00 18 represent that this part of data is a backup data identifier, and the subsequent information content includes backup time, system partition size, effective space used by the system and backup time. Among them, the backup time and system partition size are used to display the backup records; the effective space used by the system is used for the final size of the written data during restoration; the system partition size is verified before the restoration starts, if the system Inconsistencies during res...

Abstract

The invention provides an operating system backup and restoration method and system based on storage sector data. The method comprises the steps that an effective use space of a system disk partitionis acquired; all original disk data, comprising master boot record sector data, stored in the space is acquired, data compression is performed on the data, and the data is organized into backup data in a preset format; and the backup data is stored into a hidden backup partition. According to the method, the sector data (comprising the master boot record sector data) relevant to an operating system is backed up by the adoption of the preset format and stored into one hidden backup partition; and when the system cannot be entered after the system is infected with a virus or a file system is damaged, the system can be restored effectively and timely by restoring the backup sector data.

Description

technical field [0001] The invention relates to the field of data backup, in particular to an operating system backup and restore method and system based on storage sector data. Background technique [0002] As the name suggests, data backup is a process of retaining data in a certain way so that it can be reused in case of system damage or other specific situations. The fundamental purpose of data backup is to reuse, which means that the core of backup work is recovery, and a backup that cannot be recovered is meaningless to any system. In the actual situation, manufacturers or integrators are more bragging to users how clever their products are in the backup process. However, as an end user, you must clearly realize that the real life of the backup system lies in the ability to restore data safely, conveniently and efficiently. Many people may think that since the backup system has backed up the required data, recovery should not be a problem. In fact, it is not the cas...
