How to restore the system from win7 backup files?
?
● Enter the backup and recovery option settings.
From the control panel, select? System and security? Backup your computer? (System backup and recovery option, backup your computer), select here? Create a system image? Starting the backup operation is much simpler than ghost. We can choose to store the backup file in a partition of the disk (it must be in the same disk as the system partition). Or directly saved to the optical disc. Of course, it is not realistic at present. It is estimated that windows7 is preparing for the Blu-ray drive. You can also directly save the backup to any computer in the LAN, which is more suitable for office computers in the LAN. It should be pointed out that it is impossible to back up to a partition in FAT32 format. By default, when you create a system image, it automatically includes the partition where the operating system is located. If there is no doubt, click? Start backup? Button to start the backup.
The hard disk of the author's notebook is 320GB, 5400 rpm, 16mb cache. It takes 17 minutes to back up the system disk and software installation disk with a total size of 20GB, and the file size after backup is 16.7GB, which is faster if it is a desktop. This speed is similar to ghost, but the compression rate is lower. Now the hard disk is also very cheap, so it is not a big problem to take up a little more space. After the system image is created, the backup wizard will prompt whether to create a system repair media, which can be used to start the computer in the future. You can make a decision according to the actual situation.
● Select the storage location of the backup file.
Two methods of system recovery
In the past, when we needed to restore the system, we usually entered the ghost software interface through the startup menu, or made a Winpe startup USB flash drive to load the Ghost file, which was complicated to operate. In the recovery function of Windows7, we can also make a U disk startup disk to recover. Besides pressing F8 to enter the Winre system repair interface, the production method is also very simple.
● Select the full recovery function.
Method 1: Enter the restore through the advanced startup option.
When the startup screen appears, press and hold the F8 function key to enter the advanced startup mode, where we can see many startup options. Select the top one from the startup menu. Fix the computer? , you can enter the Windows recovery environment.
Step 1: Select language and keyboard layout.
After the file is loaded, we will see a prompt box. First, choose the language and keyboard layout. Naturally, the default language cannot be selected, but the keyboard layout is recommended. Chinese (simplified, PRC)-American keyboard? Of course, you can also choose the default settings.
Step 2: Select a login account
Click? Next? Button to enter the next link, it is recommended to choose the highest authority? Administrator? Account login, if not modified, the default password is empty.
Step 3: View the Repair Tool
Next, we will see the Winre interface, which contains many practical repair tools:
Startup repair: Startup repair can be used to automatically repair some common errors, such as the loss of startup manager or the loss of an item in the operation and startup menu.
System restore: system restore, which restores the system to a restore point, provided that the corresponding restore point has been created.
System image recovery: System image recovery. If you have ever created an image file for your system, you can use this tool to restore it.
Window Memory Diagnosis: Window Memory Diagnosis
Command prompt: Command prompt. In this environment, we can start most applications through the command prompt. Except for Windows Shell programs, almost all applications and scripts can run smoothly.
● Select the backup file for recovery.
Step 4: Restore the system from the image
Choice? System image recovery? The recovery wizard will quickly scan the image files on the disk. The scanned system image files are listed here. If the image file to be restored is in another destination path, you can choose? Select a system image? Confirm again. After checking, click? Twice in a row. Next? Button, after confirmation, you can restore the computer from the image file.
Similarly, when the author uses a notebook to restore, it takes 13 minutes to restore the system disk, 5 minutes to restore the software installation disk, and 18 minutes to restore the whole system and the previously installed software. This efficiency is still very good.
Method 2: Restore the startup USB flash drive of windows7 kernel.
This newspaper has introduced the production method of winpe boot disk many times before, but there are always friends who will encounter all kinds of strange problems and can't set it successfully. Now it is quite simple to make a startup USB flash drive with winre tool under windows7, without mass production tools or downloading winpe, just use UltraISO tool.
Enter the root directory of the disk where the Windows 7 operating system is located from the browser. Please open it first. Folder options? Dialog box, switch to? It seems that this will be? Hide files and folders? Set to? Show hidden files, folders and drives? , you can show hidden files, folders and drives and cancel? Hide protected operating system files (recommended)? , which is used to make the protected operating system files display normally and take effect after confirmation.
Now, we can find one called. Recover? Folder, double-click to enter? c5e5 1094-dfa6-
1 1dd-a2 a3-ECF 4 f 6976847？ Folders Please note that the subfolder names here may be different. Here you can find two files, boot.sdi and Winre.wim Please copy them to a temporary folder for future use.
Generally speaking, the backup and recovery mechanism of Windows7 consists of three parts: system and file backup and recovery based on shadow copy, file backup and recovery, and system image backup and recovery.
I. File Backup and Recovery
This function allows us to back up and restore data in any folder on the hard disk. Backup strategy supports incremental backup, and backup devices support local partition (not recommended), optical storage, external storage devices and networks.
(1) How to back up?
To use backup and recovery of files, you must create a backup plan. The following process may involve the creation of a system image, the contents of which will be described in the next section.
Enter? in the start menu? Backup? , enter? Backup and recovery? . After entering the Create Backup Plan Wizard, first select the location where the backup will be stored, and then select? Let me choose? Enter the user-defined selection interface. By default, Windows will back up all files contained in the library, files on the desktop, and other data files, so you can make choices as needed. Then select the backup time policy, review the options and save, and the selected items will be backed up immediately. At the specified backup time, the system will also automatically back up (if the backup device is online) or remind the user to back up (if the backup device is offline). At the same time? Backup and recovery? You can make a manual backup at any time in.
(2) How to restore?
Bring the backup device online. System and restore? The device will be automatically detected. Select in the interface? Restore my files? , add the files to be restored to the list. By default, only the latest backed-up files are displayed. If you need documents from previous dates, please remember to click? Choose another date? .
(3) Evaluation of file backup and recovery
The file backup and recovery function provides users with a complete and easy-to-use personal file protection mechanism. Incremental backup brings great benefits. Take my own backup as an example, including six different versions of music library and picture library from August to now, but it only takes up a little more than 3G space (the original folder is about 2.7G). Regular backup plan makes me forget to make backup meaningless; The backup folder is protected by NTFS permissions and UAC (only when stored in NTFS partition), so that it will not be damaged by virus or misoperation; Flexible recovery method, so that I can easily recover on demand?
It is recommended that you turn this feature on for important personal folders.
Second, the system image backup and recovery
This function will create a complete image of the system, which can be used to quickly restore the working state of the system during disaster recovery. The backup strategy supports incremental backup; Backup devices support local partitions (not recommended), optical storage, external storage devices and networks.
(1) How to back up?
Enter? Backup and recovery? , you can click on the left? Create a system image? Create a system image at one time, or create a backup plan to realize regular backup of the system image. In the wizard, you can set up backup devices and backup partitions. Note that in order to ensure the reliability of backup, in addition to the system partition, the system will also make a mandatory backup of the partition containing key applications (currently verified antivirus software).
(2) How to restore?
Boot into WIN RE with Windows installation CD or other means (such as F8), click Repair Computer and select Repair with System Image. Of course, please don't forget to bring the backup device online. Attention? Format and repartition the disk? Option is beneficial to improve the success rate of restore, but it will lose all the data on the existing hard disk, which is suitable for system transfer and other work. If it is confirmed that the partition information recorded by the image is consistent with the current disk partition information, it can be unchecked.
The whole restoration process takes about 15 minutes (2 1G data, measured by USB2.0 mobile hard disk).
(c) Assessing system image backup and recovery
This function is called CompletePC, which has been around since Vista and has been controversial? Because its opponent is a ghost. Users who are used to GHOST (used again? Hehe) You may sincerely look down on modules that provide similar functions, and even worse, you will go all out to find faults. BUG？ . I don't think it's necessary to settle down and have another world. From the function of system mirror backup, online backup, network backup, incremental backup, backup plan and backup folder protection are all not available in the popular version of GHOST. The high integration and reliability with the system are inherent advantages, and it is even more surprising that the VHD obtained after backup can be directly mounted. Of course, no compression ratio is not enough.
It is suggested that users who want to further improve and improve the disaster tolerance of the whole machine data should enable system mirror backup.
There are more than three thousand words. I wish I had written my paper so happily (laughs). Write a conclusion or something as usual. The purpose of this paper is to introduce, but there may be an argument because the spearhead inevitably points to GHOST and some people habitually despise the system function. Again, I don't expect anyone to change anything, but I think, when you analyze the whole backup mechanism of the system, you will find that it is not enough to backup with GHOST (in fact, the latest version of GHOST 14.0 has developed into a more comprehensive backup software, but? The authors of software such as One-Click Ghost don't seem to buy it). Hope: first, when you turn off the backup and restore mechanism of the system, please clearly understand what you are doing; Second, do you like TonyXiang's famous saying? Thought is more important than skill, and connotation is more important than appearance? This article also wants to convey such an idea.
Over. If you are interested in pictures and examples, you can update them later.
Thirdly, backup and recovery of systems and files based on shadow copy.
This function is what we often say? System restore? Or? Restore point? Yes It uses shadow copy technology to create shadow copies of files in the partition where this function is turned on.
(1) How to back up?
By default, the partition where the system is located has the shadow copy function turned on. Restore points are automatically created before major system events occur. Every seven days, if a restore point is not created in the previous seven days, it will be automatically created, but you can manually create a restore point at any time. The whole backup process will be completed quickly and will not affect the users' work. By default, the maximum space occupied by shadow copy is 3% of the partition size. When the limit is exceeded, the old restore point will be automatically cleared (which is one of the reasons why we see that the space occupied by the system partition fluctuates in intervals). Are you online? System properties? what's up System protection? Tab, we can manage and configure the shadow copy function.
(2) How to restore?
Shadow copy brings three benefits. First, you can use restore points to quickly restore system files and settings. Second, files accidentally deleted or changed in the partition can be restored to the state when the restore point was created; Third, the driver can be easily rolled back.
1. For operations aimed at restoring the system, you can enter? Restore? After entering the system restore interface, follow the wizard, or you can use the system installation CD to boot into WIN RE, select Repair Computer, and follow the wizard. This operation does not affect the user's personal files.
2. For restoring any file to the previous version, you can view the file or its parent file (grandfather, great-grandfather? ) folder properties, select? Previous version? Tab, open the corresponding time point and copy the file.
3. For the operation that you want to roll back the driver, you can enter the device manager and check the properties of the corresponding device. Driver? Select under the tab? Rollback driver? Do it.
(3) Evaluation of shadow copy
As the most basic and practical backup and restore mechanism of the system, shadow copy may be the least popular because people often put? Swallow up hard disk space? Buckle his hat on his head. 3% will scream? Swallow it? Really? I beg to differ. When you are saved by it, you will certainly appreciate the hard work of the old servant. On the other hand, I have seen many tragedies caused by turning off shadow copying? For example, a completely realistic player, whose team file has been carefully managed for dozens of seasons, was accidentally damaged. Although he used Windows 7, the shadow copy function was turned off and he had to start all over again. Maybe you will say that the game is irrelevant, but what if you lose a contract that is related to our future? Can you still? Doesn't matter? Really? Shadow copy is not only a tried-and-true regret medicine, but also a time machine that can take us back to the not-too-distant past. I strongly recommend keeping this function working properly, and turning on shadow copy on other local partitions if necessary.
Of course, shadow copies of backup data stored in the same partition are not robust enough. Once the storage device encounters a major disaster, the shadow copy will be powerless. Don't worry, Microsoft has prepared two things for us.
Windows 7 provides us with a powerful system backup and recovery tool. In fact, these tools are not multi-choice in function, but complement each other.
