Windows7 Backup and restore function decryption

We know that Windows Vista started with the introduction of backup capabilities, the system can be saved as image files, features and ghost very similar, however, Windows Vista backup function is not mature, there are mainly backup files bloated, backup file restrictions, slow reduction of the defect. Microsoft's October 22 launch of Windows 7 aims to get out of Windows Vista's shadow and regain Windows Vista lost ground. So is there any noticeable improvement in the backup and restore capabilities of Windows 7, comparable to ghost? Let's solve the mystery.

A concise system image backup restore

First, we try to back up the system in Windows 7. Our goal is to back up a 9.76GB Windows 7 system. We start the backup Restore feature of the system from start-All Programs-maintenance-backup and restore. We found that backup to Windows 7 has a link to "Create a system image" on the left, while backup restore is not available in Windows Vista.

We will be able to back up the system image of this computer is very convenient, other multimedia, documents, data files will not be backed up, later restore the system will be faster. So what is the speed of the system image creation? We can start testing by clicking the "Create System image" link. By entering the Create System Image window, we found that the system image can be saved on the hard drive, burn disc, and network location, while there is no network location in Vista backup restore, so the backup of Windows 7 's system image is more versatile and flexible.

We chose to save the system image in D and then click the Next button, when we found that the backup disk space is 10GB.

Clicking on the "Start Backup" button will start the backup process, which takes 9 minutes to generate a backup file that occupies 6.97GB, and the resulting shadow copy file will occupy the remaining space.

So how fast does Windows 7 restore a backup image? Let's continue with the test. We click the "Restore system settings or Computers" link below the Backup Restore window to enter the recovery window, and then click the "Advanced Restore Method" link under the window.

At this point in the Advanced Recovery Method window, we click on the "Use the system image created before" link to restore the computer.

Then, we click the Skip button to ignore the process of backing up the file. Books for examination

At this point, go to the "Reboot" window and click on the "Reboot" button.

After the reboot, we found that the system could not enter the restore function, it seems that this backup through the Windows 7 backup restore the probability of a successful restore is not high.

Next, we start the system by installing the CD, click the "Next" button when we enter the installation window, and then click the "Repair Computer" link in the window that appears.

After the system recovery options feature has searched for the installed Windows system, click the "No" button, select the "Restore computer using the previously created system image" option, and click the "Next" button.

At this time the image has been backed up successfully found, click the "Next" button can be.

In the window that appears, we click the Next button directly.

Finally click "Finish" to start the restore, the process of restoration lasted 8 minutes.

After testing, we found that: Windows 7 system backup restore speed is relatively fast, and ghost have a ratio, however, the stability of the restoration needs to be improved.

Second, take the library as the core system resources Backup Examination Forum

We know that backup restores of Windows Vista can also back up file resources such as photos, music, video, and so on, which makes it easy to migrate these resources to new computers, but Windows Vista is backed up by file format, which has some limitations. So is Windows 7 's backup going to break these limits? When we clicked on the "Change settings" link in the Backup window, we found that we could back up all the file resources (including documents, music, pictures, videos, etc.) from all the current users ' libraries. With the current user set up the location of the library, we can flexibly backup the various locations on the hard disk file resources, no longer have the file format restrictions, backup restore more efficient.

Taking full advantage of the virtual link technology of the library is a feature of Windows 7 backup restores, so that the backup user's data will be more comprehensive and even backup personal data files such as contacts, desktops, downloads, favorites, and so on. Ghost also fails to implement a one-time backup of multiple drive locations, which is an advantage of backup restores.

Backup restores for Windows 7 are much better than Vista, System image backups are more rapid, Windows 7 Backup to file resources is excellent, supporting library file backups is a major improvement, unfortunately the compression rate has not improved significantly. It is much faster than the backup restore of Ghost,windows 7 (ghost backup of the same system image when 22 minutes, restore time 17 minutes), Windows 7 The compression rate of the restored image is much worse than the ghost (ghost the same system image of the backup takes up a capacity of 3.58GB), however, the backup restore of Windows 7 supports scheduled and incremental backups and image files. The VHD can be hooked up directly, and these are ghost that cannot be implemented. In this way, Ghost's advantage over backup restore is only reflected in the compression rate. Therefore, in the context of continued low drive prices, the user's hard disk capacity is increasing, users use the Windows 7 Backup Restore function is also a time-saving data protection and migration means.
