Embodiment 1

[0028] This embodiment is based on the computer hard disk partition data backup and recovery method needs to be loaded into the computer system kernel with a program with partition virtual conversion and data modification monitoring functions, and its complete basic implementation process can be found in figure 1 .

[0029] First, connect the hard disk to a computer with Winodows operating system, and partition the hard disk through Fdisk in DOS or PowerQuest PartitionMagic Pro software under Windows. The partition type can be FAT32 or NTFS. After the partition is completed, modify and edit the disk sector through Microsoft's Dskprobe.exe tool (see Figure 5 ), in the primary partition table data, find the sign of the system partition. In the partition table, 01H represents the DOS partition in 12-bit FAT format, 04H represents the DOS partition in 16-bit FAT format, 05H represents the extended DOS partition, 06H represents the partition in DOS3.31+FAT16 format, and 07H repre...

Abstract

The invention relates to a method for backing up and restoring computer data, which belongs to the technical field of computer security. The method comprises the steps of establishing a hidden partition, establishing a virtual partition, backing up key files, monitoring and processing data, and restoring system data. Because an application program of a conventional operating system cannot access the hidden partition, backup files saved in the hidden partition cannot be damaged; and through the data monitoring and processing, because a data allocation unit with data files stored therein actually cannot be occupied and the original data files are saved appropriately, the security of a computer is guaranteed practically. Besides, the processes only back up a file allocation table and a file directory table, and the data files are unnecessary to be backed up, thus computer resources are almost not occupied, and the backup and the restoration are quick. The method has low requirements on users and is convenient to be popularized and applied.

Description

technical field [0001] The invention relates to a method for backing up and restoring computer data, in particular to a method for backing up and restoring data based on computer hard disk partitions, and belongs to the technical field of computer security. Background technique [0002] With the rapid development of computer networks, how to ensure the security of computer systems has become a concern. Some network Trojan horses, worms and other viruses and some rogue software are updated very fast, and can easily bypass the monitoring of anti-virus software and firewalls, causing troubles to computer operations at least, and directly causing computer paralysis. [0003] For this reason, in addition to computer security software such as various antiviruses and firewalls, there are also various software for system backup and restoration, such as virtual restoration, ghost, etc. Some of these backup software divide independent hidden partitions as data partitions. backup, and...
