Problems solved by technology

Because these methods require users to make backups "foresightedly" in advance, and the backups must be preserved before they can be restored, but in fact it is difficult for users to "foresight" in advance, and such backups are often very large, and backups and preservations take a long time. time and a large storage space, which brings troubles and obstacles to the user's actual operation, and most users often have to reinstall the operating system after a period of time to clean up junk software

Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0029] Such as figure 1 As shown, the data backup of the computer hard disk:

[0030] a) Create a backup partition on the computer hard disk, create a backup module, a monitoring module, a scheduling module and a first recovery module on the computer;

[0031] b) the backup module takes a snapshot of the data of the regular partition of the hard disk of the current computer as the root data, and the time point where the root data resides is used as the starting time point, and the root data is stored in the mobile phone, wherein the mobile phone is provided with a second recovery module, Encryption module and decryption module, the second recovery module comprises: the operating system and the recovery software that realize computer startup such as Linux or winPE, hard disk ...

Abstract

The invention discloses a computer data backup and recovery method, belongs to the field of information safety and can be used for realizing the fact that a computer system can be recovered to the state of a happened random time point from a current state. The method is characterized in that back-up partitions are established on a computer hard disk, data manipulation events on sectors of conventional partitions of the hard disk are intercepted by a monitoring module, if the data manipulation events are a file system, which is capable of changing the conventional partitions of the hard disk, on the sectors, a hard disk operating log is established, and the hard disk operating log is stored in back-up partitions; and the time point corresponding to the current state of the computer is b, the computer returns to the time point a, a first recovery module takes the hard disk operating logs corresponding to all time points between the time point b and the time point a, and all hard disk operating logs taken by the first recovery module are overlaid in sequence according to the chronological order from the time point b to the time point a and are covered on a current hard disk .

Description

technical field [0001] The invention relates to a method for backing up and restoring computer data, which belongs to the field of information security. Background technique [0002] Nowadays, computer applications are very popular, and people's daily life is completely inseparable from computers. This has also brought computer viruses, Trojan horses, backdoors, spyware, rogue software, etc. to invade and destroy. Computer systems are easily invaded and controlled by these malicious software, which may lead to the leakage and loss of user information or the collapse of computer systems. Users generally use anti-virus software to take precautions, but the prevention effect is not satisfactory. Due to the restriction of the hysteresis of the virus database, the system security under the protection of anti-virus software is still very fragile. In particular, some rogue software tends to stubbornly reside in the user's computer system, and it is difficult to remove and recover...
