Introduction to the backup and restore functions of Win7 system (1)

The backup and restore of the system is a key component in the system. In Vista, system backup and restore functions have been enhanced. This article specifically introduces the backup and restore scheme of the win 7 system, so that users can easily know and use.

1. Use System Restore to easily return to the soul

System Restore is a standard system function that has become a core component of the system since Windows ME. As the system is upgraded, this feature is more complete. The system restore function of Windows 7 is still greatly improved compared with the previous system.

On the desktop, right-click on the computer and select Properties to go to the System page of the Control Panel. In the left pane, click the System Protection link to enter the System Restore Settings window.

(1) System settings and file version restores

For Windows 7, system restore includes system settings restore and text version restore, which we usually call System environment and shadow copies. Normally, Windows 7 only has system protection enabled in the system partition, and includes both system restore and file version restore. However, in Windows 7, system restore and file version restore can be split. The usual practice is to enable system restore and file version recovery at the same time in the system partition, and only open the file version restore in other partitions. This not only improves system performance, but also saves disk space. The setting method is to select the disk partition that needs to be set in the system protection tab, and then click the configuration button to enter the configuration page. You can see that there are three options under the restore settings: selecting the first restore system settings and the previous version of the file will open the system restore and shadow copy of the partition; select the second to restore only the previous version of the file only open The shadow copy feature of the partition; selecting the third item to turn off system protection will turn off both functions in that partition.

(2)Manually create a restore point

After the system recovery of the partition is enabled, its system partition will create a restore point to the system at intervals (default once a day), or install the application on the system. The restore point is established when the software and driver. For the other non-system partitions, only the shadow copy function is enabled, and when the file in the partition is modified, a shadow copy of the file is created. It should be noted that when setting protection for a partition, you first need to create a restore point for the partition, so that system restore is available when performing system restore or file recovery. The method of creating a restore point is very simple. Click the Create button in the System Protection tab to pop up the Create Restore Point Wizard. Follow the wizard to complete the creation of the restore point.

(3) The way the system is restored

In general, system restoration is a last resort. Generally, it is used when a certain software or driver is installed and the software conflicts, and the system is unstable or even crashes. As far as Windows 7 is concerned, there are two ways to restore the system: one is to enter the system in the system properties window, click the system protection tab, first select the system partition that needs to be restored, and then click System Restore. The button launches the System Restore Wizard,

Selecting a Recent Restore Point Follow the wizard to complete the system restore process. As for the restore of the file version, you can right-click on the file to select the previous version, and then select a version from the file version list to restore or copy.

Sometimes the system is more serious and cannot be started in normal mode. At this point we can try to enter the safe mode to start the system restore, if you can not enter the security mode, we can choose to restore the system from the system recovery options console to restore the system. Press and hold the F8 key while the system is booting to enter the system advanced boot options menu, select Repair computer and press Enter to enter the System Recovery Options console. In this process, you need to select a user and enter a password to log in. Select and click System Restore to launch the System Restore Wizard, and the restore process is the same as in normal mode. In addition, running Startup Repair starts the system repair function, which runs System Image Recovery to recover the system from the backed up system image. It should be noted that Vista can also perform system restore in offline state, but it needs to use the Vista system installation disk to boot the system into the system recovery options console. In Windows 7, there is no need to install a disk, because Windows 7 has integrated it into the system.

2, free custom backup and restore

Windows 7 backup and

Restore function Compared with Vista's similar features, the biggest improvement is to add new options With these options we are free to customize and control system backup. Execute the control panel rarr; all control panel items rarr; backup and restore can enter the Windows 7 backup and restore center, where we can complete the system backup and restore is all operations.

(1) System Backup

After Windows 7 installation and deployment, it is necessary to make a Windows backup, which is very necessary for system recovery and migration. In the Backup and Restore Center, click the Set Backup link to launch the Widnows System Backup Wizard. We can save the backup to any non-system partition with enough space on the local, and of course it can be saved to a network location, such as a file server. Enter its UNC address in the network location, along with its network credentials such as username and password. If you want to save it locally, I recommend that you save it in a partition of another local hard disk. For backup content, Windows 7 saves data from all users' libraries, desktops, and Windows folders by default, and also creates a system image. Of course, some backup items are not what we need, so we can customize what we want to back up as shown in Figure 5. Here we can check the content that you want to save (such as the library, user-related content in the system disk and application information, etc.), if you do not need to save the system image, you can remove the system including the drive System Reserved, (C:) A tick in front of the image.

It is important to note that after customizing the backup task, the system will perform the backup plan every Sunday at 19:00, which is very easy for some administrators to ignore. Someone once set up a backup task and did not modify the default backup plan. Since the system was backed up, the system did not even perform a backup because his PC was running at 19:00 on Sunday. In this regard, we can modify according to their own needs, generally set the backup to a relatively idle time period of the working day. In addition, we can also set the frequency of system backup. For system security requirements, you can set up a backup every day. After the Windows Backup setup is complete, click on the Enable Schedule button and the system will perform the backup according to the schedule you set. Of course, we can also perform an immediate backup or change the backup plan.

(2) System Restore

Generally, when the system is faulty, unstable, or reinstalled, the system configuration can be quickly restored or migrated through the restore function. Enter the backup and restore center of Windows 7, users can restore from backup as needed. For example, you can restore only my files and restore all user files. In addition, we can also restore from other backups. Of course, if you have done a backup of the system image before, you can perform a restore of the entire system. Click Restore System Settings or Computer Link to enter the System Recovery window and click the Advanced Recovery Method link to enter the Advanced Recovery Method window. Here, there are two recovery methods for you to choose: First, restore the computer with the image, provided that the system image has been created before; second, reinstall the system with the Windows 7 installation disk, and then restore our files from the backup. These two methods have their own advantages and disadvantages, and everyone can choose according to their needs.

3, system integration system imaging tools

(1) prepared system image backup

No doubt, system image backup is the most thorough backup in Windows system backup This is also a job that system administrators must do. In fact, doing system image backup is not only based on precautions, but also to facilitate the rapid deployment of systems in the LAN. A dedicated system image backup tool is available in Windows 7, so we don't need third-party tools to easily back up your system image.

Also in the Windows 7 Backup and Restore Center window, click the Create System Image link in the left pane to launch the Create System Image Wizard. For security reasons, it is not recommended to save the system image on the same disk as the system, because if this disk fails, the system will not be able to recover from the image. Based on this consideration, you can save the system image on a DVD disc or save it somewhere on the network.

(2) Lifesaving straw system repair CD

System error or even crash is inevitable, there is a repair CD often can make the system come back to life, in Win

dows 7 A system repair disc can be created using the tools provided by the system. In the Windows 7 Backup and Restore Center window, click the Create System Repair CD link in the left pane to launch the Create System Repair CD Wizard, which allows you to easily create a system repair disk. You can see that the two key files Winre.wim and boot.sdi are on the CD, responsible for system booting and repair. Booting the system with the system repair disc has the same final effect as the system repair that comes with Windows 7. However, the system repair disc is more widely used. When the repair computer can't enter, the repair disc comes in handy. In addition, this system repair CD can be used for booting and repairing of the Vsita system.

4, powerful system packaging tools Dism

System packaging is of course also a category of system backup and restoration. In Windows 7, Dism replaced ImageX as a new system packaging tool. Let's take a look at the application of Dism in system image operations.

Dism is a new tool that is unfamiliar to most users. You can get the parameters and examples by typing the command dism /? at the command line.

First, we can use Dism to get the system version information in the image, and execute the command dism /get-wininfo /wimfile:c:testimagesinstall.wim. The install.wim is the installation package of Windows 7, and the get-wininfo parameter is used to obtain the package information.

Secondly, we can use the Dism command to load the system image in any directory. The command is dism /mount-win /wimfile:c:testimagesinstall.wim /index:4 /mountdir:c:testservicing to execute dism /get-mountedwiminfo gets the information about loading Dism images. The Dism/image and /online parameters are used to implement the operation of the Dism load system image. For example, run the command dism /image:c:testservicing /add-driver /driver:c:testdriversUX6000vx60000.inf to add a new drive to the target system image. Run the command dism /image:c:testservicing /get-drivers to view the driver information.

If you want to uninstall the Dism image, you can execute the dism /unmount-win /mountdir:c:testservicing /discard command. In addition, execute dism /image:c:testservicing /get-intl to get the language information of the current image. Dism /image:c:testservicing /set-uilang:zh-cn is to set the system language to Chinese, dism /image:c:testservicing /set-timezone:China Standard Time is to set the system time to Chinese standard time. The use of Dism is more complicated, and it can be used flexibly to implement various operations on the system image.

Summary: Windows 7 provides us with a powerful system backup and restore tool. In fact, these tools are not multiple choices in function, but complement each other and complement each other. In actual combat, everyone should make a clever match according to their needs, so that they can make their own strengths and ensure our data and system security.
