Hard disk data backup and restore method, system and computer

Abstract

The invention discloses a hard disk data backup and restoring method, a system and a computer; the hard disk data backup and restoring method comprises the following steps: on a virtual machine manager layer, weather write operation of at least one operation system which is operated on the virtual machine manager layer is carried out to a hard disk port is monitored, when the write operation is monitored to be carried out, a sector number of a target sector, corresponding to the write operation, is recorded; according to the sector number, the data in the sector is backed up, and the backup is that the data in the sector is stored in a protective subarea; in addition, the current time point is used as a first identification of a first time point; according to the first identification, the backup data at the first time point and the backup data before the first time point are restored to the corresponding sector, and the backup data before the first time point comprises original backup data.

Description

technical field [0001] The invention relates to the technical field of computer information security, in particular to a hard disk data backup and recovery method, system and computer. Background technique [0002] With the popularization of informatization, computers have become a necessary tool for people's daily work or life. As the most important storage device of a computer, the hard disk is particularly important to ensure its data security. With the proliferation of computer viruses, the data in the hard disk is in fact often in an unsafe state. In addition, defects in some software or misoperation by users may also lead to loss or damage of data in the hard disk, bringing great inconvenience to users. [0003] It is difficult to completely avoid situations such as virus infection or user misoperation, so the current protection of hard disk data mostly adopts the method of data backup and recovery. The more common method is to use disk backup software such as ghost...

Problems solved by technology

However, since this solution requires the installation of additional drivers, and the loading of the drivers depends on the operating system, it is necessary to customize different drivers for different operating systems. When multiple operating systems are installed in a computer , the interception of hard disk operations also needs to rely on multiple customized drivers to achieve, causing inconvenience to management and maintenance

In addition, in the process of installing patches to the operating system, abnormal situations may also occur: because the installation of operating system patches often requires restarting, some patches installed before restarting will be located by the hard disk drive to a special hard disk address

After restarting, before the driver is loaded, the patch installation program writes to the hard disk again. At this time, the hard disk driver cannot intervene in the write operation, resulting in inconsistent system updates, which may cause some unpredictable operating system failures
