Description
Technical Field
The invention relates to the technical field of computers, in particular to an information maintenance system based on a computer.
Background
At present, computers are mostly arranged in classrooms of schools and offices of teachers; due to teaching needs, teachers or students often copy files out of or into removable storage devices. For the endless virus layer of the removable storage device, the illegal invasion of the virus into the removable storage device often causes that after the removable storage device is inserted into one poisoned computer, other computers are cross-infected after the other computers are inserted, even when a user accesses the same poisoned computer by using the new removable storage device, the new removable storage device is infected again. When the viruses enter the computer, the viruses cause damage to information stored in the computer, and when the viruses are heavy, the viruses directly cause paralysis of the computer, so that huge information security risks are caused.
In order to prevent virus intrusion, besides various anti-virus security software, various system backup and restore software such as virtual restore and Ghost is presented, wherein some backup software performs backup in a file manner by dividing independent hidden partitions as data backup.
Although the backup methods have certain beneficial effects, the backup methods need to actively perform backup in advance, and once the backup is performed, all information in the current state is lost, and some useful teaching files, settings, software, data and the like are also completely deleted. Because these methods require that the user must "see far" in advance and the backup must remain intact to recover, in practice, the user is difficult to "see ahead" in advance; moreover, such backups tend to be quite bulky, requiring long time and large storage space for backups and preservation, which presents practical operational difficulties and operational difficulties for users.
For this reason, a system for information maintenance that quickly performs information recovery is required.
Disclosure of Invention
The invention aims to provide an information maintenance system based on a computer, which aims to solve the problem of low information recovery speed in the prior art.
In order to solve the technical problems, the technical scheme of the invention is as follows:
the information maintenance system based on the computer comprises a storage hard disk with a conventional partition established, and further comprises:
the processing module is used for establishing a first backup partition in the storage hard disk;
the monitoring module is used for acquiring the data operation event in the conventional partition and judging the content of the data operation event; if the content of the data operation event is a file for changing the conventional partition of the hard disk, the monitoring module sends a first backup instruction;
the backup module is used for generating a data operation log based on the current data operation event after receiving the first backup instruction and storing the operation log into the first backup partition;
the first recovery module is used for recovering data under the current operating system of the computer;
when the current time point A is required to be restored to the time point B, the first restoring module invokes all data operation logs from the time point A to the time point B from the first backup partition; the first recovery module sequentially overlays the data operation logs into the conventional partition according to the sequence from the time point B to the time point A.
Modifying files of the conventional partition of the hard disk comprises modifying original files and creating new files; the processing module is also used for establishing a second backup partition in the storage hard disk; when judging the content of the data operation event, if the data operation event is creating a new file in the conventional partition of the hard disk, the monitoring module also sends a second backup instruction; and the backup module is used for storing the created new file to the second backup partition after receiving the second backup instruction.
The monitoring module is also used for judging the created new file type, and if the created new file type is a preset file type, the monitoring module sends a second backup instruction; the backup module is also used for carrying out screenshot on the new file when the created new file is opened after receiving the second backup instruction, and storing the screenshot to the second backup partition; the first recovery module is further used for sending selection information for recovering the new file or the screenshot when the first recovery module recovers the data under the current operating system of the computer, and when the first recovery module receives the selection information for recovering the new file, the new file is sequentially overlapped and covered from the second backup partition to the conventional partition based on the data operation log; when the first recovery module receives selection information for recovering the screenshot, the screenshot is stored from the second backup partition to the conventional partition.
The basic scheme principle and the beneficial effects are as follows:
after the computer is infected by virus, the computer can be quickly recovered from the current time point A to the time point B through the first recovery module; compared with the existing virtual restoration, the restoration modes such as the Ghost and the like need to completely cover the current hard disk data by using backup data, only the data between the time point A and the time point B need to be overlapped and covered according to the data operation log, the operation is simple, and the restoration speed is higher.
If only the data operation log is backed up, the file itself is not backed up. When the virus irreversibly damages the file itself, the file cannot be restored through the data operation log, for example, some luxes viruses encrypt the file, and the encrypted file cannot be restored only through the data operation log. By backing up the created new file, the new file is convenient to recover when being irreversibly damaged.
The computer can create a large number of new files in the use process, some of the files are cache files created in the program running process, some of the files are data files which are created by users independently, and the data files are document files with smaller volumes and multimedia files with larger volumes. If all the files are backed up indiscriminately, the burden of the computer is certainly increased, and the running speed of the computer is slowed down. In the preferred scheme, only the preset file types are backed up, so that the burden of a computer can be effectively reduced, and the occupation of resources is reduced.
When the user recovers the data, whether to recover the screenshot or not can be selected; double insurance is realized through two backup modes of screenshot and preset file, the probability of complete information loss can be effectively reduced, and the lost information can be conveniently retrieved by a user.
Further, the processing module is further configured to automatically set the predetermined file type or set the predetermined file type based on the modification information after receiving the modification information.
The automatic setting of the preset file type can simplify the operation of the user, and the user can send out change information to change the preset file type autonomously, so that the operation is more humanized.
Further, a mobile storage device is included; the processing module is also used for creating a second recovery module in the mobile storage device; the backup module is further configured to store the data of the current time point of the storage hard disk as backup data, store the backup data in the mobile storage device, and mark the time point where the backup data is located as a backup time point C.
The backup data is stored in the mobile storage device, so that the mobile storage device can be started to restore the data when the data on the storage hard disk is destroyed and cannot be restored, the remote backup is realized, and the safety is higher.
Further, when the computer cannot run the current operating system, the mobile storage device is inserted into the computer, and the computer is started through the second recovery module; after the computer is started, the second recovery module is used for covering backup data in the mobile storage device into a conventional partition of the storage hard disk, and the second recovery module is used for calling all data operation logs from the current time point A to the backup time point C in the backup partition; and the second recovery module sequentially overlaps and covers the data operation logs into the conventional partition according to the sequence from the backup time point C to the current time point A.
When the current operating system of the computer is destroyed and cannot be started, the data can still be recovered through the mobile storage equipment, so that the security is high.
Further, the data operation log includes an operation time and an operation content.
Recording the operation time helps to restore the data within a prescribed time interval.
Further, the second recovery module includes a startup unit and a recovery unit.
The restore unit facilitates restoration of backup data stored in the mobile storage device.
Further, the storage hard disk comprises a solid state hard disk or a mechanical hard disk.
Both the solid state disk and the mechanical hard disk are currently mainstream computer storage hardware devices, and any one of the solid state disk and the mechanical hard disk is selected to realize data storage.
Further, the mobile storage device includes a mobile phone, a usb disk, a mobile hard disk, or an optical disk.
And a plurality of mobile storage devices are supported, so that a user can conveniently select proper devices to backup and restore data according to actual conditions.

If the data operation event is only creating a new file in the regular partition of the hard disk, the monitoring module also judges the type of the created new file, and if the type of the created new file is a preset file type, the monitoring module also sends a second backup instruction.
The processing module is also used for automatically changing the preset file type or manually changing the preset file type based on the changing information after receiving the changing information. The predetermined file types include word, ppt, excel, and the like. The user may send modification information to the processing module to manually modify the predetermined file type, or may automatically modify the predetermined file type by the processing module, where the modification includes adding or subtracting the predetermined file type.
The backup module is used for generating a data operation log based on the current data operation event after receiving the first backup instruction, and storing the data operation log into the first backup partition; the data operation log includes operation time and operation content. The backup module is further configured to store the created new file to the second backup partition after receiving the second backup command.
The first recovery module is used for recovering data under the current operating system of the computer; when the current time point A is required to be restored to the time point B, the first restoring module invokes all data operation logs from the time point A to the time point B from the first backup partition; the first recovery module sequentially overlays the data operation logs into the conventional partition according to the sequence from the time point B to the time point A. Wherein when the data operation log relates to a new file stored in the second backup partition, the first recovery module sequentially overlays the new file from the second backup partition into the regular partition based on the data operation log.
Example two
The computer-based information maintenance system differs from the first embodiment in that: also included is a mobile storage device; the processing module is used for creating a second recovery module in the mobile storage device; the second recovery module includes a startup unit and a recovery unit.

In this embodiment, a usb disk is used.
When the computer cannot run the current operating system, the mobile storage device is inserted into the computer, and the computer is started through the starting unit. When the computer is specifically started, the BIOS is entered after the computer is started, then the BIOS is set as the USB flash disk for starting, and the operating system pre-installation environment in the starting unit can be loaded after the computer is restarted, for example, the operating system pre-installation environment is a winpe under WINDOWS. The foregoing is the prior art, and is not described herein.
After the computer is started, the recovery unit is used for covering backup data in the mobile storage device into a conventional partition of the storage hard disk, and the recovery unit is used for calling all data operation logs from the current time point A to the backup time point C from the first backup partition; retrieving the stored new file from the second backup partition; and the recovery unit sequentially overlaps and covers the data operation logs into the conventional partition according to the sequence from the backup time point C to the current time point A. Wherein the data operation log relates to new files stored in the second backup partition, and the restoring unit sequentially overlays the new files from the second backup partition into the regular partition based on the data operation log.
Example III
The difference between the computer-based information maintenance system and the first embodiment is that the backup module is further configured to, after receiving the second backup command, perform a screenshot on the new file when the created new file is opened, and store the screenshot to the second backup partition.
The first recovery module is further used for sending selection information for recovering the new file or the screenshot when the first recovery module recovers the data under the current operating system of the computer, and when the first recovery module receives the selection information for recovering the new file, the new file is sequentially overlapped and covered from the second backup partition to the conventional partition based on the data operation log; when the first recovery module receives selection information for recovering the screenshot, the screenshot is stored from the second backup partition to the conventional partition.
When the user recovers the data, whether to recover the screenshot or not can be selected; double insurance is realized through two backup modes of screenshot and preset files, and the probability of complete information loss can be effectively reduced. For example, after the backed-up word file is destroyed, if the user selects to restore the screenshot, the content of the word in the screenshot can be obtained through the restored screenshot, so that the user can conveniently retrieve the lost information.
The foregoing is merely exemplary embodiments of the present invention, and specific structures and features that are well known in the art are not described in detail herein. It should be noted that modifications and improvements can be made by those skilled in the art without departing from the structure of the present invention, and these should also be considered as the scope of the present invention, which does not affect the effect of the implementation of the present invention and the utility of the patent.
