This article describes the difference between Windows 7 system protection, system image and scheduled backup (user TOM asked), here are three concepts put on Windows 7 is actually five, They are: create restore points, create system images, create system repair discs, schedule backups, and restore files. We often say that system protection generally refers to the creation of restore points, that is, the system protection settings (Control Panel - "System" in the computer system properties window, and all of these protection items can be collectively referred to as system protection strategies.
Note: This article is only used as a difference in the understanding of several related concepts of the Windows 7 system protection strategy. For the specific implementation method, please refer to the article link and subsequent article introduction.
First, Windows 7 system protection
Windows 7 system protection is a function to periodically create and save computer system files and settings related information, system protection also saves the previous version of the modified file, it will save these files in the restore In the point, create these restore points before major system events (such as installers or device drivers)....(This definition is from Microsoft official)
So, we often say that system protection means creating restore points. As long as the system protection is turned on (the default is open):
1, the default will automatically create a restore point every seven days
2, will also create a restore point when installing Windows drivers or applications.
3, when the file is modified, it will also generally create a restore point (requires NTFS format partition, and open protection).
4, you can also manually create a restore point.
About the restore point settings please refer to: Windows 7 system protection settings and usage points
Windows 7 system protection and GHOST difference: Windows 7 system protection and traditional one-button GHOST comparison
So, Windows 7 system protection is only Refers to the creation of restore points, relative to the entire system, just incremental backup, so if the system hangs, the use of restore points may not be fully recoverable (please note that this is different from the system repair in Windows 7), but for some modifications The file's backfile may be valid.
Second, Windows 7 create system image
Windows 7 system image is very similar to GHOST, system image support is manually created or created in the scheduled backup, when creating a system image, the system disk is required, you can also choose to include other Drive, so Windows 7 system image protection is for the drive, is all "backup", compared to Windows 7 system protection, Windows 7 system image supports various restore strategies, such as startup, network, mobile storage, etc. Wait.
The only downside is that the Windows 7 image file compression ratio is very low. Tianyuan measured the creation of a 9.7G system disk. After the creation, the system image should reach more than 8 G. In short, the system image of Windows 7 needs to be done manually, which is different from the system image creation method in the planned backup below (and the result may be the same).
Three, Windows 7 scheduled backup
Windows 7's scheduled backup is also called automatic backup, the default is also closed, scheduled backup can be oriented to the entire drive (so you can also choose to include the system drive), you can also face some files And the folder is carried out, which is more flexible, which is also an important feature of the planned backup.
Scheduled backup details, please refer to: Windows 7 backup and restore settings and usage points
Fourth, Windows 7 to create a repair CD
Windows 7 system repair CD, is in the system when a serious error, you can use CD boot into the system repair options (system repair options please refer to: basic topics: Windows 7 advanced boot options diagram) to help you repair Windows. In the created system repair CD, there are actually only four files (except the boot file), so it can only be used as a boot-in repair option. As for the recovery process and effect, it depends on the above restore points, images, and scheduled backups. content.
About Windows 7 system repair CD production, there will be an article to fill the map tomorrow, let everyone see together to repair what is in the CD.
5, Windows 7 system restore
Windows 7 system restore contains the following:
1, restore from restore point
2, restore from image
3, restore from scheduled backup
all These restore contents can be accessed either on the Windows 7 platform or in the Windows 7 boot repair interface.
Integrated:
1. From the concept of functional module partitioning, the file version restoration and planned backup in the system protection overlap, and the system images in the system image and the planned backup overlap.
2, in addition to repairing the CD, in fact, whether it is system protection, system image or scheduled backup, in the Windows 7 system restore location has reached a unified.
3, TOM users of the problem, "and the article also wrote "and backup system image". The previous system image has been backed up. Why should I back it up here?...”, it is a scheduled backup. As for how to back up and back up, it is definitely set by the individual.
4, TOM users on the backup space, Tianyuan first answer you, even if the image backup is based on the actual use of space, not how big the C drive will be, and whether your plan backup includes Other drivers, otherwise the space does not exceed the free storage space should be no problem, it is recommended that you capture the map to my mailbox (including error map, backup process step capture and drive use space capture).
