Abstract

A backup of a computer system and a restoring method for selectively implementing the system backup and general restoration are provided to backup a hidden folder by extracting a user boot sector when installing a program. If the backup and restoration program of the computer system start to be installed in a user computer, the system information of the user computer is read(S11). The program extracts the information of the boot sector among the user system information(S12). The program produces the virtual partition in the computer system drive of the user. The extracted boot sector information is stored in the virtual partition to one file. The virtual console and program file are set up(S13). The user selectively controls the system backup and reconstitution(S15).

Description

{Method for restoration and backup of computer system}

The present invention is a method for restoring a system by using a virtual console of Windows, in particular, by reading and saving a boot sector separately, providing a multi-boot menu, and backing up and restoring a computer system so that a user can easily restore the system. It is about a method.

The development of computer technology, coupled with the change to the information society, is bringing innovative changes in human life, and the spread of computers is increasing day by day so that it is recognized as a necessity of life in offices and homes.

Such a computer manages resource management, allocation and execution of applications of a computer system by an operating system called an operating system (OS), which not only creates an environment in which a user can use the computer, but also provides various applications and information. Stored.

Therefore, general users perform various tasks using a computer with an operating system such as Windows or Linux. If the above operating system is destroyed due to a user's mistake, a virus, or information collision between peripheral devices, etc. If you can't use your computer anymore, it's very important to safely recover the broken operating system.

In general, files of a computer installed with Windows, Linux, etc. are composed of various file systems such as FAT (File Allocation Table), NTFS (NT FileSystem), EXT2 / 3, etc. And it means that the file system is destroyed, and the restoration of the destroyed operating system means to restore the destroyed file and the file system to the environment that can use the computer.

In fact, restoring the operating system allows users to back up their files on floppy disks, CD-ROMs and other hardware devices in case they need to, and then read and restore the backed up files in case of system problems.

However, such a method requires additional media such as floppy disks, CD-ROMs and other hardware devices for the program for backup and restore, so that the program loses backed up media in the event of a system crash. Or, if the media is destroyed, there is a problem that immediate restoration of the computer system is impossible.

In view of the above-mentioned problems, there is a known method of backing up and restoring a computer system that can be safely and conveniently restored to the original operating system using a program built in the system during the booting process. The method requires that the computer system's hard disk be divided into two or more partitions.

1 is a diagram illustrating a drive structure of a general computer system. As shown here, the partition is divided into two drives (C :, D :) on the hard disk, and a superblock that stores information of each drive, and whether a specific sector in each drive is currently in use. And a directory entry indicating a directory structure and a plurality of files.

Therefore, if you analyze the FAT on each drive, you can extract only the sectors that are currently in use.The process of compressing and encrypting the extracted sectors and storing them as files in an arbitrary area of another partition is the process of drive backup. If the system's operating system is destroyed and the system can no longer be operated, the data block is read from the backed up file, and then the compressed and encrypted sectors are decrypted and decompressed to restore the original partition on the hard disk. Restoration is done by writing in situ on the drive.

As described above, currently available computer restoration programs generally require a partition of a hard disk to backup an operating system. That is, there is a problem in that the restoration program can be installed and used only when at least two hard disk areas of the computer system are separated.

Also, when you install the restore program, you need to create a separate partition. This partition space should be the size that is entered in the program, not just the size that novice wants. There are difficulties to see and learn in detail.

Due to such reasons, even if the restoration program is installed at the time of purchase of a PC, beginners may not use the restoration program directly because of difficult usage.

In addition, since information on backup and recovery is registered in the system tray after installing the conventional restoration program, the booting process is significantly slowed or occupies a lot of memory. This has the disadvantage of slowing down the system booting speed as the number of boot attempts and backup information are stored in the buffer area at that time.

In view of the above-described problems of the prior art, the present invention extracts and backs up a boot sector, and enables booting with a backup file by user selection at boot time. An object of the present invention is to provide a method of backing up and restoring a computer system that enables backup and restoration regardless of the above.

The present invention is to automatically file after reading the user's boot sector and to provide a multi-boot menu using the boot sector and to back up and restore the files of the system in the form of a single virtual console.

In addition, the present invention can back up the files and windows when the user wants, and help each beginners to easily back up and restore the system by explaining as a help or a picture for each menu for beginners easy to understand without the need for a separate manual It is for.

In addition, the present invention is to improve the boot speed of the virtual console of the program is less than 250 megabytes smaller than the capacity of the existing virtual console type.

The present invention is to automatically file after reading the user's boot sector and to back up and restore the files of the system in the form of a virtual console using the boot sector.

Restoration method of the present invention is divided into a total of four methods, and after the installation on Windows automatically restored by the virtual console booting method and the three methods of normal restore, date-by-date restore and optimized restore after booting Windows. do. Installed on Windows, users can use the functions between the three menus to display the user's one-step help.

The fourth method is System Restore, which reads the user's system boot sector information, saves it as a file, and then presses the "HOME" key to enter virtual console mode.

Normal restore, date-by-date and optimized restore methods, after a normal Windows boot, use the virtual console to back up important "DLL library" files on Windows, allowing users to use the PC for long periods of time or to shut down the system due to unknown errors. Can be restored.

System restoration is a method of restoring a window system after booting with boot sector information backed up using the multi-boot menu which was backed up before the whole system is down or the window does not enter.

The virtual console can be used to store CDs and boot from CDs. In recent years, as more mobile phones are available, they can also be stored as mobile phones.

In the current recovery program, image recovery, file recovery, and virtual partition recovery become mainstream, and if the existing backup program continuously backs up to the hidden area, there is a disadvantage in that the virtual buffer becomes unreasonable. If the virtual buffer takes up a lot of space, the boot speed will slow down significantly and the disk usage will increase.

The present invention extracts only the boot sector and does not touch the existing system at all and installs it as a general file. The program installed as the general file backs up and restores only the basic area of Windows and can be restored from a single disk that does not exist previously. Another advantage is that you can delete the "System Volume Information" folder in Windows.

 The "System Volume Information" folder is the basic system backup program area of Windows, and it is a folder that cannot be deleted even with the highest level of authority. The basic system backup program of Windows saves the area immediately when a new program is installed in the system. Virus infected files are also automatically saved in the folder, so they cannot be repaired by various virus cleaning programs.

As described above, according to the present invention, when the program is installed, the user boot sector is extracted and backed up in a hidden folder, and the virtual console booting is performed by the backup boot sector file by a specific key input in addition to the window booting during booting. This allows system restoration without the need for a separate boot means.

In addition, the present invention has the effect of selectively implementing a system backup, normal restore, restore by date and optimized restore by activating the virtual console after the boot window by installing the virtual console.

In addition, since the present invention displays a virtual console menu on the screen and provides a menu for backup and restore, even a beginner can easily use backup and restore.

In addition, the present invention can be restored from a single drive without damaging the existing partition because the backup folder is formed as a hidden folder and restored using a backup file of the virtual partition. And because the capacity of the virtual console is small, a large effect that can be applied using a separate storage medium can be obtained.

In addition, the optimized restore in the Windows menu optimizes the system in addition to the recovery points in the "System Volume Information" folder, and allows uninfected virus infected files in the "System Volume Information" folder to be easily infected with viruses without any external influences. It has the effect of deleting files.

When installing a computer backup and restore program on the user computer system, the program installation management unit extracts the boot sector of the user computer system, creates a virtual partition area as a hidden folder, and stores the information of the extracted boot sector as a single file. 100);

Provides interface with user by providing menu screen for backup and restore so that user can control backup and restore of computer system, and virtual console by backup saved boot sector information by specific key input which is preset at system boot. A virtual console unit 200 for controlling booting;

A backup controller 300 which copies a corresponding folder or file or a user system registry and a DLL file according to the backup menu selection of the virtual console unit 300 and stores the copied folder or file in the virtual partition area;

In accordance with the restore menu selection of the virtual console unit 300, the user restores the file system by copying the DLL file and registry information backed up by the backup control unit to restore the original location, and automatically activates the restore function of the window system. Restoration control unit 400 controls the restoration by date to control the restoration to a file of the desired date, and optimization restoration to restore the original location by copying the backed up DLL file and registry information after deleting unnecessary files It is characterized by.

According to the present invention configured as described above, the system boot sector is extracted and stored as a single file, and in the case where the system does not boot, a specific key set in advance without using a separate booting means (for example, boot CD or boot diskette) is used. If a user inputs (eg, a "HOME" key), the booting is performed by a file of a boot sector previously stored as a file according to the present invention. Then, the virtual partition is created to store the backup files in the virtual partition, and restore the registry and DLL files backed up to the virtual partition to the original location.

Selecting a virtual console menu by pressing a specific key (eg, "HOME" key) predetermined at the time of booting of the user computer system (S101), and when not inputting a specific key for booting the virtual console, general Windows booting is performed. When the specific key is input, the virtual console booting step (S102) is performed. The virtual console boot is booted by reading the boot sector file, that is, the system file of the program, which is extracted from the boot sector when the program is installed and stored in a hidden virtual partition.

When the virtual console is booted as described above, the virtual console restoration program operates to display the virtual console menu on the screen (S103), and reads the existing system drive information when the program enters the window.

When booting the virtual console according to the present invention, a backup program selection and a restore program selection menu are displayed on the screen while being displayed on the virtual console menu screen, and selecting a backup program by the user's selection (S104), and a restore program. Selecting step S106 is performed.

When the user selects a backup program, a backup step (S105) of copying and storing the contents of the "Window" folder into a hidden folder which is a virtual partition created by the present invention is performed.

When the restoration program is selected, a restoration step (S106) of copying "Windows" backed up to the hidden folder which is the virtual partition and overwriting the existing system is performed.

5 is a flowchart illustrating a backup and restore method using a virtual console when booting a window according to the present invention.

After the system is booted by a normal Windows program, when the virtual console program installed by the present invention is executed, the virtual console screen is displayed as shown in FIG. 5 and the 'system backup', 'normal restore', ' 'Restore by date', 'Optimize restore' menu is displayed, and the user selects one of them to execute.

The system backup step (S20) performs a step (S21) of copying the user system registry and the DLL file, and storing the copied file in a hidden folder which is a virtual partition created by the present invention (S22).

General restore step (S30), the step of reading the backed up DLL file and registry information from the hidden folder (S31), and the step of saving and restoring the files copied from the hidden folder to the Windows system folder (S32) To perform.

Restoration step by date (S40), the step of automatically activating the restore function of the window system (S41), and the function to automatically create a registry and the window restore point to restore to a file of the desired date and restore the window Restoring to a file of the date by the function (S42).

The optimization restoration step (S50) is to restore by deleting unnecessary files, and performs the step (S51) of reading the backed up DLL file and registry information. In operation S52, a restoration point deletion decision is selected. When the deletion decision is made, all files at the restoration point are deleted and then restored (S52). That is, after all the restore points of "System volume Information" are deleted, the step of restoring the DLL file and the registry information (S52) is performed. If the restore point is not determined, step S54 of restoring the file copied from the hidden folder which is the virtual partition back to the Windows system folder is performed.

According to the present invention configured as described above, the program installation management unit 100, which installs the program of the present invention, extracts and stores the boot sector, extracts the boot sector during program installation, and creates a hidden folder as a virtual partition. The extracted boot sector information is stored in the hidden folder as a file. In addition, when booting by the general window is performed, the virtual console unit 200 may perform a system backup by user selection as shown in FIG. 4 by selecting and operating the virtual console menu. Restoring on Windows, general restoration, restoration by date and optimization restoration are selectively performed by user selection.

On the other hand, the system restore is to restore the entire system by using the virtual console menu, as shown in Figure 3, when pressing a specific key during system boot, it is possible to select the boot by the virtual console, select the virtual console boot If you do this, boot the virtual console using the boot sector information file you backed up, and then restore the entire system. This is to restore the system by copying the boot sector file and the entire window files backed up to the hidden folder which is the virtual partition.

In the current recovery program, image recovery, file recovery, and virtual partition recovery become mainstream, and if the existing backup program continuously backs up to the hidden area, there is a disadvantage in that the virtual buffer becomes unreasonable. In addition, if the virtual buffer takes up a lot of space, the booting speed is significantly slowed and the disk usage is increased.

The present invention extracts only the boot sector and does not touch the existing system at all and installs it as a general file. The program installed as the general file backs up and restores only the basic area of Windows and can be restored from a single disk that does not exist previously. Another advantage is that you can delete the "System Volume Information" folder in Windows. Here, the "System Volume Information" folder refers to a basic system backup program area of Windows and a folder that cannot be deleted even at the highest level. The basic system backup program of Windows saves the area immediately when a new program is installed in the system. Virus infected files are also automatically saved in the folder and cannot be cleaned by various virus cleaning programs.

In this situation, a novice can easily eliminate the hassle of having to install a system for the first time at the touch of a button.
