Problems solved by technology

However, the current system backup methods almost always back up system data in one file or several files. These system backups are based on the fact that at least one partition of the hard disk still exists, and the file system of at least one partition can still be used. The backup can be restored. If these conditions cannot be met, then the backup plan cannot be executed, or even if it is executed, the backup data package cannot be found; if the backup file is found, but if the backup file is partially damaged, it may also cause system backup. The file cannot be used; or if some sectors of the hard disk are damaged, it may also make the system unrecoverable

Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] Because computers used in practice are often invaded by viruses or data are damaged or lost due to other accidents, the system data is backed up to restore the system with the backup data when the system data is damaged. Because the backup data usually exists in the form of files, and the storage of files in the computer must rely on the file allocation table to manage them. The file allocation table is a data area that is extremely vulnerable to virus attack and damage in the computer, which results in that when the file allocation table is damaged, the system cannot be restored even if there is a backup. Of course, there are other situations where the file allocation table is damaged in practice, such as incorrect formatting.

[0021] The computer system restoration method provided by the present invention can solve the above-mentioned problems very effecti...

Abstract

The invention discloses a method for recovering a computer system. It includes baking up the system data as a data package, separating the said baked up data package into several data blocks, each data block being coded with a address, encapsulating the data block having address code. When recovering the system being carried, the data block is found out according to based address mark, then the data block is determined whether the block is damaged or not. If the data block is not damaged, the block is used to recovery the system directly; otherwise with the block being corrected first, the itis used to recover the system. The invented method can recover the system by checking integrality of data and recovering error data through physically read directly without dependent on partition table. So the method provides features of simple, efficient and high reliability.

Description

Technical field: [0001] The invention relates to a computer system security protection method, in particular to a computer system recovery method. Background technique: [0002] From the perspective of computer system security, system security can be attributed to the safe storage and use of system data. In order to prevent the stored data from being damaged, lost or encountered other damage, data backup methods are usually used to solve the above problems. However, the current system backup methods almost always back up system data in one file or several files. These system backups are based on the fact that at least one partition of the hard disk still exists, and the file system of at least one partition can still be used. The backup can be restored. If these conditions cannot be met, then the backup plan cannot be executed, or even if it is executed, the backup data package cannot be found; if the backup file is found, but if the backup file is partially damaged, it may ...
