Abstract
The invention discloses a method for not restoring write-ins in an overall restoring condition of a computer system. The method comprises the steps of establishing a device and distributing a symbolic link for an upper layer to access; adding a filter driving program between a driving program of a file system and an application layer; acquiring a data packet transmitted from the application layer to the file system; judging whether the data are needed to be stored and synchronously writing the data in the device established in the first step; restoring normally written data when a computer is rebooted and directly writing the data a person wants to store in a disc for storage by making the data bypass the filter drive program of the file system and a disc filter drive program of restoring software. The data the person wants to store will not be restored even when the computer is rebooted while the data and files the person is not willing to store are restored.
Description
Technical field
The present invention relates to a kind of method of not reducing that writes, especially relate under the overall reducing environment of a kind of computer system and write the method for not reducing.
Background technology
At present; Be applied in the overall protection software in the computer system, can protect data in the hard disk after computer is started shooting again, all changes all can be reverted to over; In school; Government, and be widely used on office and the home personal computer, play preventing that virus damage and system from increasing the slack-off problem of back system service time.The Previous System reduction technique the reduction total system in, also the computing machine user want to preserve get off such as mail, information such as upgrading antivirus software are reduced in the lump.Therefore the computing machine user antivirus software of having at every turn all upgrade again.Perhaps the computing machine user vital document be put into the computer system desktop perhaps " my document " afterwards, after computer was started shooting again, vital document also will be lost.
Data security always is very important branch of information security field, and relates to two important techniques in this branch: backup-and-restore.The Ghost backup software of Symantec is typical case's representative adopting redundancy technique; It is characterized in that the hard disc physical sector duplicated and be compressed to a file; Return to the data of this document on the hard disk by the sector again during recovery, thereby realize protecting data.Reduction card, system's multipoint restoring and fast restore three phases have been experienced in the development of reduction technique.In addition, divide, be divided into the reduction of overall reduction and file again from the reduction scope.
The present situation of existing overall fast restore technology is; After disk " reduction " type software and activation have been installed in the system; The write operation of all application layer files---create, revise, delete; And the variation of the setting of various systems, registration table, even comprise partition format,, system all returned to the state when activating restore software after restarting fully.The presentation of this " recovery " is not really to have what mechanism helping us to return back to initial state to the various operations of file system behind.In fact; After in case restore software is activated; Ours just no longer is effectively to all write operations of file, is all write in some temporary spaces on the disk, such as in untapped bunch or the pre-assigned particular memory file; And distributed to effective sector that file takies in the disk partition, one can not be written into yet.Because the reduction driver of file system lower floor resets bit table through one in the internal memory, help us safeguarding the linking relationship of the fast and topmost paper system architecture of these dirty datas that newly write, so we think that still various file operations are all normally carrying out.But after system restarted, the non-lasting bit table that resets had disappeared in the internal memory, and driver also is in init state, and more crucial is that one of effective sector of the original distribution of file system there is not change yet.So the disk partition structure that we see through file system also is not change.
Summary of the invention
In order to solve the existing in prior technology deficiency; The present invention provides under the overall reducing environment of a kind of computer system and writes the method for not reducing; This method is saved in the partial data under the system reducing protection on the hard disk, thereby realizes can not being reduced after computer system restarts.
The technical solution adopted for the present invention to solve the technical problems is:
Write the method for not reducing under the overall reducing environment of a kind of computer system; Comprise the method that loads disk unit and write data synchronously; Said loading disk unit and the method that writes data synchronously relate to disk drive and load disk unit and file system filter and drive and obtain file system and drive the technology that writes the information of data and write the disk unit of loading synchronously, below are loading disk unit and the detailed step that writes the method for data synchronously.
Said loading disk unit and the method that writes data synchronously comprise following steps:
Step I, create an equipment and distribute Symbolic Links for upper access;
Add a filter drive program between Step II, file system driver and the application layer, obtain the packet that application layer is passed to file system, judge whether to need to preserve these data and write I synchronously to go on foot in the equipment of creating;
The equipment created of Step II I, I step obtains the II step and writes directly data to be write after the request and preserve in the hard disc apparatus;
Step IV, computer are after restarting, and the data that system normally writes are reduced, and want that the data of preserving have walked around the disk filtration drive of file system and restore software and write direct disk and be able to and preserve.
Beneficial effect of the present invention: in computer system totally under the environment of protection, with computing machine user designated directory, such as " my document ", computer system desktop etc. penetrate the protection of reduction, directly are saved on the hard disk; The protection of the data penetrating system restore software after perhaps the program of user's appointment being upgraded such as antivirus software; Directly be saved on the hard disk; Let data be able to preserve, restart computer and also can not be reduced, and do not want be reduced the same of data of preserving with file.
Description of drawings
Fig. 1 is a theory diagram of the present invention.
Embodiment:
Be easy to understand understanding in order to make technological means of the present invention, creation characteristic and to reach purpose, further set forth the present invention below in conjunction with specific embodiment.
Referring to Fig. 1, the data that system normally writes will be squinted by the interception of the disk filtration drive of system reducing software, and after system restart, be reduced.And do now on the basis of disk reduction protection system; Reloading a volume equipment to fdisk comes out; The inlet that the another one that this volume equipment is fdisk reads and writes data, the data that system normally writes are fallen by disk filtration drive interception skew, increase a file system driver; It is a to loading on the disk volume equipment that gets up that the fashionable data sync that we write system copy is write by system; And the data that write through this inlet, the disk filtration drive of system protection software will can not be tackled its write operation and will be able to data are preserved, and the data that catalogue that the computing machine user is wanted to keep or designated program write preserve.
Write the method for not reducing under the overall reducing environment of a kind of computer system; Comprise the method that loads disk unit and write data synchronously; Said loading disk unit and the method that writes data synchronously relate to disk drive and load disk unit and file system filter and drive and obtain file system and drive the technology that writes the information of data and write the disk unit of loading synchronously, below are loading disk unit and the detailed step that writes the method for data synchronously.
