Problems solved by technology

[0004] In the hard disk data backup method adopted at present, there are some limitations in its backup and recovery, that is, either the entire hard disk is backed up, or a partition is backed up, and the entire hard disk or a partition is restored according to the mode during backup during recovery, and if the user has many For example, sometimes it is necessary to restore the entire hard disk, and sometimes only one of the partitions needs to be restored, but the backup based on the entire hard disk cannot restore only one partition, and the backup based on partitions cannot restore the entire hard disk
In order to restore both the entire partition and the entire hard disk, two backups must be performed, one for a partition and the other for the entire hard disk, resulting in redundant backups, wasting manpower, time, and hard disk space

Embodiment Construction

[0061] Such as figure 1 Shown, in one embodiment of the present invention, control computer realizes the program of data backup and recovery of the present invention is placed in the FLASH ROM chip of BIOS, realizes the backup of IDE hard disk data and recovery in the process of running BIOS. During the startup process of the computer, the user can press the backup hotkey to enter the backup function menu, or press the restore hotkey to enter the recovery function menu. In the backup function menu, the partition information of the entire hard disk and the data in the partition can be backed up. In the restore function menu, the backup data information can be restored to the hard disk according to the user's wishes.

[0062] During the POST (Power On Self Test) process of the BIOS, if figure 1 As shown, if the user presses the system recovery hotkey or the system backup hotkey, the BIOS will set the corresponding flags. After completing the detection and initialization of each...

Abstract

A method for backing up and recovering data in a hard disk, used to back up data in the hard disk, including the following steps: partitioning a segment in the hard disk as a data backup area; backing up the partition status and at least one partition data needed to be backed to the data backup area; and locking the data backup area to forbid other application software or operation system to access it. The present invention can backup and recover the data in the hard disk safely and reliably and also can ensure the safety of the backup data. <IMAGE>

Description

technical field [0001] The invention relates to a computer hard disk data backup and restoration method. Background technique [0002] As one of the most commonly used external memory for computers, hard disk is used to store operating system information and a large amount of data, and its security and reliability are very important. User misoperations, defects in hard disk data management software, and computer virus attacks may destroy useful data on the hard disk. Therefore, it is very important to back up hard disk data, so that some key data content can be restored when necessary. [0003] Among the hard disk data backup methods currently used, one is to back up the information of the partition or hard disk into a file, open the file when restoring, and restore the backup content to the original partition or hard disk. This backup method is based on Based on the file system, once the file system is damaged, if the partition storing the backup file is deleted due to a ...
