Description

System rescue method and device

The present invention relates to the field of computers, and in particular, to a method and apparatus for system rescue.

Background technique

Installing a patch is a process that modifies an already installed program, including applications, utilities, operating system and operating system components, device drivers, and so on. Patching is useful for modifying programs for a variety of purposes, including correcting program errors, reducing or eliminating security risks, or improving the logic used by the modified program. Patching is typically initiated by the company or other organization that originally provided the program to install the patch.

The installed program is mainly composed of executable code modules. As an example, many programs designed to run on the WINDOWS XP operating system from Microsoft Corp. of Washington Redmond are primarily composed of executable code modules called "EXE". A popular traditional method of installing patches is to identify executable code modules containing the program code that you want to patch with in the executable code module that makes up the installer to be patched; create a new version of the identified Executing a code module in which the required modifications have been made; and assigning a new version of the identified executable code module to the installer along with the installer to the user who wishes to apply the patch. Each user then determines if it wishes to apply the patch, and if so, executes the installer that replaces the original version of the identified executable code module with the new version of the identified executable code module.

In the prior art, a computing system for automatically implementing a received code patch is provided, comprising: a library of pre-installed help functions; and an install patch agent that receives code patches, each code patch corresponding to a set of executable modules And identifying a help function in the library, and, when an executable module of the group corresponding to the received code patch is executed, calling a help function identified by a code patch corresponding to the executable module group including the executable module Confirm with the execution value.

The above technical solution solves the technical problem of a conventional example in which it is necessary to create a plurality of patches for allocation to implement individual modifications to a single program.

However, today's users use a wide variety of operating system versions, many of which are "optimized versions" from the folk production group, which reduces the system's resource share and saves hard disk space by reducing unnecessary service modules and operating modules. . Because these folk optimized versions are quite different from the official version of the operating system production company, and the patches are often designed by the operating system production company for its officially produced full version, there will be some problems after the patch is installed. Not only as Therefore, even the original operating system may have an operating system error or even a crash after the user installs the patch due to the difference in the version, or even the official patch error, so that the user cannot enter the operating interface of the operating system again.

detailed description

The preferred embodiments of the present invention are described with reference to the accompanying drawings, and the preferred embodiments of the present invention are intended to illustrate and explain the invention.

1 is a general flow diagram of a method of system rescue in accordance with an embodiment of the present invention. In FIG. 1: Step S102: The first operating system is used as the current operating environment, and files and/or environment settings necessary for starting and entering the operating system are backed up before performing predetermined processing on the first operating system.

It should be noted that the inventors found in the process of implementing the present invention that the reason is that the installation is supplemented. After the file is filed, the Trojan is checked, etc., the problem that the operating system cannot be restarted is because the installation of the patch file and the killing of the Trojan usually modify some files and/or environment setting information necessary for booting and entering the operating system, such as杲The modified file and/or environment setting information no longer meets the conditions for starting and entering the operating system, which will make the user unable to enter the operating interface of the operating system. In order to be able to repair the operating system after the above problems occur, the embodiment of the present invention proposes a specific solution, in which an application program can be installed in the operating system (for the convenience of description, the present invention is implemented. In the example, it is referred to as "system repair software", and various steps in the embodiments of the present invention are performed by the system repair software.

In this step S102, a list of location information and identification information including file or environment settings may be generated according to all or part of the backup of the file or environment settings. The location information is used to indicate the location to be restored, and the identifier information may be an MD5 value. All or part of the backed up files or system settings can be all necessary files and/or environment settings to boot and enter the system, or they can be modified when performing some sort of predetermined processing (including patching, killing Trojans, etc.) Part of the file and/or environment settings necessary to boot and enter the system. That is, there may be a lot of files and/or environment settings necessary to start and enter the system, but when performing some sort of processing, you may only need to modify some of the files and/or environment settings, so you can only These may be backed up by modified files and/or environment settings. In this case, when the specific implementation is implemented, the system repairing program, the file to be modified, may be notified by an application that executes the predetermined processing, such as a vulnerability repairing program that performs patch processing, a killing program that performs a killing Trojan processing, and the like. And/or environment settings, so that the system fixer can first back up these files and/or environment settings to the specified path before performing the scheduled processing, and at the same time, record the location to be restored. With the backup of the above content, at least ensure that the system can be started normally by recovery.

Step S104: installing a second operating system, so that the first operating system cannot be operated normally, using the second operating system as the current operating environment, and performing the first operating system according to the backed up file and/or environment settings. restore.

After the system recovery software backs up the files and/or environment settings necessary to boot and enter the operating system, the second operating system (for example, MSDOS system, etc.) can be installed, and after the second operating system is started, it can be automatically run. A program for performing the following operations: recovering the first operating system according to the backed up file and/or environment settings. For example, the restoring step may be: searching for a location to be restored according to the location information, and identifying the required backup content by using the identification information, and then restoring the required backup content, the recovery action including using the backed up content. Insert, replace, delete, or restore all or part of the original environment settings with the environment settings of the backup. The recovery step may also be to perform an uninstallation procedure to unload the file or restore the environment settings, which are typically processed files or environment settings after the backup.

Wherein, if the corresponding list is generated in step S102, the restoration may be performed according to the location information and the identification information in the already generated list. For example, restore the processed file or post-processing environment settings to the backed up files and/or environment settings.

In addition, step S104 may also be to restore all the files and/or environment settings necessary for starting and entering the system to all the files and/or environment settings necessary for starting and entering the system.

In addition, the full or partial backup can be implemented by establishing a restore point, and the restore can be performed by the restore point using the restore program of the second operating system or the third-party restore program or the restore of the first operating system simulated in the second operating system. The program is implemented. The so-called restore point indicates the storage state of the computer system file, which is equivalent to the time point when the backup is recorded after backing up many files and information. In the embodiment of the present invention, the backup operation in the system repair software can be understood as creating a system restore point. The so-called restore program is to read the above-mentioned restore point, and then restore the system to the state of the restore point. The simple understanding is to restore all the files backed up at that point in time to the current system.

After the above steps are completed, the first operating system is restarted. If the first operating system still fails to operate normally after the first operating system is restarted, the second operating system is used as the current operating environment (ie, the second operating system is restarted. Operating system), recovering with predetermined file and/or environment settings, wherein the predetermined file and/or environment settings include files and/or environment settings stored in the memory designated location prior to step S1. The file and/or environment settings stored in the memory designated location prior to step S1 may be, for example, files and/or environment settings backed up by the system at the previous recovery step, backup files and/or environment settings saved earlier, Or restore the system backup files in the disk and so on.

Further, the above step S104 may further be that the second operating system is started by the user, and all or part of the backup file and/or environment settings are restored by the program in the second operating system. In addition, you can use the second operating system as the current running environment to back up the part to be restored before restoring the backed up files and/or environment settings.

The first operating system and the second operating system include but are not limited to: a Windows system, a Linux system, a DOS system, and a Unix system. With the system rescue method of the embodiment, the file and/or environment settings in the computer can be performed before installing patches, killing Trojans, killing viruses, software upgrades, cleaning plugins, cleaning system garbage, and cleaning system traces. Record, in order to prevent the system from recovering due to the installation of patches, killing Trojans, killing viruses, software upgrades, cleaning plug-ins, cleaning system garbage, cleaning system traces and causing abnormal operation, thus preventing the system from performing the above predetermined processing. A failure has occurred and cannot be used anymore. The invention can be recovered under the condition that the first system cannot operate normally, which makes the system more secure, and, because of installing patches, killing Trojans, killing viruses, software upgrades, cleaning plug-ins, cleaning system garbage, cleaning systems Before the trace, the program automatically records the files on the computer, so there is no need to manually back up the files before the patch is installed, which improves the efficiency.

Hereinafter, the embodiment shown in Fig. 1 will be further explained by a specific embodiment. Figure 2 shows this particular embodiment.

Example 1

2 is a flow chart of a method of system rescue in accordance with one embodiment of the present invention. In Fig. 2: Step S202: It is determined whether or not predetermined processing needs to be performed.

Among them, the predetermined processing includes: operating system installation patches, killing Trojans, killing viruses, software upgrades, cleaning plug-ins, cleaning system garbage, cleaning system traces, and the like.

Step S204: In the case where the determination result is YES, the file and/or environment settings to be modified when performing the predetermined processing are backed up, and the second operating system is installed.

Step S206: Generate a list corresponding to the file and/or environment setting to be modified when the predetermined process is executed, wherein the list contains location information and identification information of the file and/or environment setting to be modified.

Step S208: Restore the predetermined processed file or the predetermined processed environment setting to the backed up file and/or environment setting according to the processing list.

This embodiment shows a specific method of the embodiment shown in Fig. 1. In this embodiment, the operation to be performed by the system is first detected. If the system is to perform patch installation, killing Trojans, killing viruses, software upgrades, cleaning plug-ins, cleaning system garbage, cleaning system traces, etc., the system may be caused. When a failed operation occurs, the backup step is initiated in case the system fails to function properly.

The specific manner of restoring the processed file or the processed environment setting to the backed up file and/or environment setting may be that the uninstalling program is executed or simulated in the second operating system. An operating system uninstaller that unloads processed files or post-processing environment settings to achieve system recovery, but can also be a replacement, insert, or delete action on a file or environment setting.

The system rescue method of this embodiment detects whether to perform patch installation, killing Trojans, killing viruses, software upgrades, cleaning plug-ins, cleaning system garbage, cleaning system traces, etc., thereby determining whether to perform backup. The system recovers when the system fails. In this way, the system automatically performs backups, eliminating the need for manual manual backup operations, and eliminating the need for backup operations without threat systems, thereby improving efficiency and saving system resources. . In addition, the present invention can also automatically perform selective backup of the content that needs to be backed up by including a list of location information and identification information set by the file and/or the environment, thereby saving user time and avoiding the user's incorrect selection. problem.

The method of system rescue of the above embodiment will be specifically described below by way of a specific example. Instance

During the running of the computer, a vulnerability patch for the Windows operating system generated by Microsoft Corporation is usually detected on the network through the bug fixer. After that, the vulnerability fixer prepares to download and install the patch to the user's computer. In this process, you need to modify the file ntoskrnl.exe and the environment setting msconfig.exe (system configuration utility) necessary for system startup. Therefore, before the execution of the specific patch installation work, the system 4 can be backed up by the system 4, the software n ¹ ntoskrnl .exe and the msconfig.exe provided by the embodiment of the present invention, and a list is generated, which includes the above two The location information of the files and the MD5 value, after which a second operating system is also installed. Then the vulnerability fix performs the patch installation operation, the file ntoskrnl.exe and the environment setting msconfig.exe are updated, the updated file ntoskrnl.exe and the environment setting msconfig.exe are obtained. Next, the computer restarts, but due to ntoskrnl The .exe and / or msconfig.exe files are incorrect and cannot enter the Windows operating system. At this time, the user can select to enter the second operating system (such as the Linux operating system) created by the system recovery software. In the operating system, a program is automatically started, and the program searches for the updated ntoskrnl.exe according to the above list. Revert to ntoskrnl.exe before installation, and find the updated msconfig.exe to be restored to msconfig.exe before installation. Finally, restart your computer to enter the Windows operating system.

It should be noted that, in the embodiment of the present invention, the system recovery software is installing the second operating system. After that, the boot entry option of the second operating system may be added to the current first operating system for the user to make a selection; when the user restarts the current first operating system, the two operating systems are activated. If the user finds that the first operating system cannot be started after selecting the first operating system startup item, the user can select the startup item of the second operating system, and the second operating system will automatically run, and then a program will be automatically run. The program will automatically restore the first operating system file and/or environment settings that have been backed up to the specified location, and then automatically restart the computer. After the restart, the user can also see two operating system startup items, which can be selected. If the startup item of the first operating system can normally enter the first operating system, the application that has previously performed some predetermined processing in the first operating system can clear all backup files and traces through the system repair software, so that When restarting again, the user will no longer see the second operating system. Motivation. Of course, in order to implement the aforementioned method of repairing files and/or environment settings backed up during the historical repair process, it is not necessary to clear the files and/or environment settings for the repair backup after completing a repair.

The second operating system of the present invention can be installed at the same time as the software for performing backup/restore, or before or at the same time for all or part of the backup of the file and/or environment settings, and can be installed before the scheduled processing is performed.
