The core of one-key recovery technology: Principle Application

&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; The core of one-click Recovery Technology is the boot of the backup partitioning system. The computer always boots the active primary partition (up to three primary partitions on the same hard disk) at startup. As long as a specific program resides in the MBR, you can control which partition is activated and which system is booted.

Set up two primary partitions on the same hard drive, one for Windows XP and one for DOS. Activates the partition where the DOS system is located when Windows XP crashes. by Config.sys and Autoexec.bat two files, automatically completes the ghost mirror file to the partition load, completes the recovery function.

Depending on the structure of the hard disk, the location of the backup partition should be the end partition of the entire hard disk. Because this is the area that the head is infrequently accessed, away from the system partition, it is not easy to produce bad way, ensure the security of the backup file. This puts a higher demand on the DOS system as a backup. Typically, the DOS system must be installed on the first primary partition of the hard disk, and the current condition requires that the DOS system be installed in the final primary partition. Such DOS systems can only be asked for MS-DOS 7.0 (DOS under Windows 98). Also, the file system of the partition in which DOS is located must be in FAT32 format.

We now use more of the system than Windows XP, plus the necessary drivers, commonly used applications, and so on, the size of more than 2GB. Use Ghost height compression (up to about 50%) with a mirrored file of approximately 1GB. To ensure data security, the size of the backup area will be around 2GB. If you want to back up multiple systems, be sure to tailor, determine their corresponding space size.

In order to further protect the data backed up, the partition is required to appear when the system is restored, but not at ordinary times, either in DOS or under Windows.

In fact, this is exactly the principle of IBM's dedicated recovery program bmgr and hardware setup requirements. The recovery program Bmgr resides in the MBR and gives the following tips when powering on:

To Start IBM Product Recovery, press F11

Within 2 seconds of the prompt, press the F11 key to activate the recovery system (the DOS system above) for automatic system recovery. After restarting the computer, the partition is hidden again.

The "one-key recovery" principle ends here.
