Detailed introduction to the restore and backup mechanism under Win7 system

Backup, restore has always been a key component in the system It is understood that in Vista, system backup and restore functions have been strengthened. And Windows7's "Backup and Restore" function is similar to Vista's similar functions. So, what kind of backup and restore scheme is provided in Windows 7? This article will discuss the Windows7 system backup and restore mechanism and everyone. Experience.

This article will introduce the backup and restore mechanism of Windows 7. In fact, the core of this backup and restore mechanism has been laid in the era of Vista, and I still pay tribute to Vista.

In summary, the backup and restore mechanism of Windows7 consists of three parts: system and file backup based on shadow copy (short shadow copy), file backup and restore, system image backup and restore.

First, file backup and restore

This function allows us to back up and restore data in any folder on the hard disk. Incremental backup is supported on the backup policy. Local partitions (not recommended), optical storage, external storage devices, and networks are supported on the backup device.

(1) How to back up?

To use backup and restore of files, you must create a backup plan. The creation of a system image may be involved in the following process, and the contents of the system image are described in the next section.

Enter "“Backup" in the Start menu and go to “Backup & Restore”. After entering the Create Backup Plan Wizard, first select the backup storage location, then select “ Let me select & rdquo; enter the custom selection interface. Windows will back up all files contained in the library, files on the desktop, and other data files by default, so you can choose as appropriate. Then select the backup time policy, review the options and save, the system will immediately back up the selected items. At the specified backup time, the system will also automatically back up (if the backup device is online) or remind the user to make a backup (if the backup device is offline). At the same time, you can perform manual backup at any time in "Backup & Restore".

(2) How to restore?

Bring the backup device online, <;System & Restore> will automatically detect the device. In the interface, select “restore my files<quo;, and add the files that need to be restored to the list. By default, only the most recently backed up files are displayed. If you need files with previous dates, please remember to click “Select Other Dates”.

(3) Evaluation of file backup and restore

The file backup and restore function provides users with a complete and easy-to-use personal file protection mechanism. Incremental backup brings huge benefits. Take my own backup as an example. It contains 6 different versions of music library and photo library from August to now, but it only takes up a little more space than 3G (the original folder is about 2.7G); regular backup plan makes me not make backups meaningless because of forgetting; backup folders are protected by NTFS permissions and UAC (only when stored in NTFS partitions), so that they are not subject to viruses or misuse Destruction; flexible restore method that allows me to easily restore on-demand ……

It is recommended that you enable this feature for personal important folders.

Second, system image backup and restore

This feature will create a complete image of the system, which can be used to quickly restore the system's working state in the case of disaster recovery. Incremental backup is supported on the backup policy; local partitions (not recommended), optical storage, external storage devices, and networks are supported on the backup device.

(1) How to backup?

Enter “ Backup and Restore”, you can either click “Create System Image” on the left side to create a system image at one time, or you can pass Create a backup plan to implement regular backups of your system image. The backup device and backup partition can be set in the wizard. Note that in order to ensure the reliability of the backup, in addition to the system partition, the system also forces the backup of partitions containing critical applications (currently known as anti-virus software).

(2) How to restore?

Boot into WIN RE with Windows installation CD or other methods (such as F8), click to repair the computer and you can choose to repair with system image. Of course, please don't forget to let the backup device come online. Note that the "Format and Repartition Disk" option will help improve the success of the restore but will lose all the data on the existing hard disk, suitable for system transfer and other work. If you confirm that the partition information of the image record is consistent with the current disk partition information, you can leave it unchecked.

The entire restore process takes about 15 minutes (21G data, USB2.0 mobile hard drive measured). Previous12Next page Total 2 pages
