Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, by the following examples, and with reference to accompanying drawing the present invention is described in more detail.
The objective of the invention is to propose a kind of hard disc data backup and restoration methods, be used for the significant data of simple backup and recovery computing machine, be user-friendly to, lower the after service cost of computer vendors simultaneously.Fig. 1 shows the mode of setting up according to system bootstrap district backup area 101, operating system backup area 102 and the user data backup district 103 of a preferred embodiment of the present invention.Please refer to Fig. 1, the foundation in system bootstrap district backup area 101, operating system backup area 102 and user data backup district 103, can comprise following steps: (1) is since a specific logical address, set up a system bootstrap district backup area 101, its size is fixing, does not adjust with backup procedure; (2) after system bootstrap district backup area 101, set up an operating system backup area 102, back up and recover at C dish, and do not change the partition table of hard disk reality, occupy himself requisite space of spatial division by the backup of reality; (3) after operating system backup area 102, set up a user data backup district 103, back up and recover at the user data dish, and do not change the partition table of hard disk reality, occupy himself requisite space of spatial division by last backup actual.Specific logical address described in the step (1) can be the actual maximum address of hard disk.After the user carries out the recovery of C disc system, state, i.e. factory state when the C dish is system backup.This moment, the C dish did not have other data.After the user carried out the recovery of D dish data, state when the D dish is got back to last data backup did not have other data.
In the present embodiment, in the backup of operating system backup area 102 at the operating system data, should be in user data backup district 103 data for empty or discharged under all customer data backup area 103 data conditions and carry out.
Please refer to Fig. 1,, realize the foundation of each backup area in the present embodiment by following concrete steps.
At first mark off the data backup zone of one section hard drive space as hard disc data, this section zone is a hidden area, and is invisible under operating system, is not subjected to the influence of FDISK software, can not be formatted.The specific implementation method is to mark the data backup hidden area of the high-end continuous regional space of one section logical address on the hard disk as DISK to Image by the maximum address that hard disk is set.The foundation of hidden area can order the maximum address that hard disk is set to be realized by the SET MAX that the hard disk areas defencive function that hard disk itself is had is supported.
As shown in Figure 1, the maximum address recognized that hard disk is set by SET MAX order is mAd, and just the hard disk address hAd with reality comes out to the area dividing between the mAd, as hidden area.Hidden area is divided into system bootstrap district backup area 101, operating system backup area 102 and user data backup district 103, and this three subregion is separate, but places in order.
As shown in Figure 1, the actual maximum address of hard disk is defined as hAd, and the end address of system bootstrap district backup area 101 is defined as sAd1, and the end address of operating system backup area 102 is defined as sAd2, and the end address in user data backup district 103 is defined as mAd.Like this, among the whole hidden partition between the mAd, seamlessly be divided into three zones at hAd, i.e. system bootstrap district backup area 101, operating system backup area 102, user data backup district 103 by sAd1 and sAd2.
The size of system bootstrap district backup area 101 is fixed, and will no longer change in case divide.By the quantity of calculating the actual subregion of hard disk, the type of subregion, the information such as size of hard disk partition table, can calculate its maximum possible value, its length may be defined as fLength, and unit is a byte.Can calculate sAd1 according to sAd1=hAd-fLength.
The size of operating system backup area 102 is decided according to the size of operating system by producer according to the C dish, may be defined as sysLength.103 when being empty in the user data backup district, promptly during mAd=sAd2, and operating system backup area 102 adjustable size.Can calculate sAd2 according to sAd2=sAd1-sysLength.When carrying out system backup in producer, the calculating of operating system backup area 102 sizes carries out.When not backing up, sysLength=0, i.e. mAd=sAd1.103 when being empty in the user data backup district, promptly during mAd=sAd2, and operating system backup area 102 adjustable size.It is backup operation system repeatedly of producer.Size when its size is last the backup.In case user data backup district 103 is not empty, promptly during mAd ≠ sAd2, operating system backup area 102 sizes are just no longer adjustable.Be that sAd2 will fix.System can not back up again.When not being empty, change the size in user data backup district 103 if desired, promptly need again the backup operation system, then need at first to discharge user data backup district 103, make mAd=sAd2 again in user data backup district 103.
The size in user data backup district 103 decides according to the size of the data content that the user deposited in the D dish, may be defined as dataLength.User data backup district 103 sizes always can dynamically be adjusted.Can calculate mAd according to mAd=sAd2-dataLength.The calculating of user data backup district 103 sizes is carried out when the user carries out data backup.When not backing up, dataLength=0, i.e. mAd=sAd2.Under any circumstance, with backing up user data repeatedly per family.D dish user data size when the size in its user data backup district 103 is last the backup.Carried out data backup as the user, then backup operation system again of producer.Unless at first discharge user data backup district 103, with the data deletion of user ID, just backup operation system again.
If the user changes partition table, then need backup partition table separately, but do not influence the system recovery of C dish and the user data restore funcitons of D dish.If the partition table after the user change has only 1 or 2 subregions, promptly the user with DISK to Image only for C dish or C, the D dish, then data backup function should be forbidden automatically.Hard disk remaining space deficiency when backing up as data should be able to provide prompting and forbidden data backup functionality.
Above preferred embodiment, respectively at system bootstrap district backup area 101, operating system backup area 102, and the length setting in user data backup district 103, have been described in detail, on the basis of above accurate Calculation, the hidden area that is used for data backup on the hard disk can satisfy compression to greatest extent on the basis of using, and has improved the utilization ratio of hard disk.
According to the present invention, because system data back-up and user data backup and the complete separate operation of recovery are independent of each other, it is simple more clear and definite that the user is operated.Because system recovery is nonupdatable, does not bring damage so the user worries the maloperation meeting of oneself to system, simultaneously, does not worry the virus problems that the user has a headache most.If generation poisoning intrusion, or the damage that brings operating system owing to misoperation of users, the user only need start shooting and press resetkey again, just can be with the state of operating system recovery before dispatch from the factory, but also do not worry losing of important documents.Simultaneously, for the user problem that can not solve has taken place, do not had faults such as sound as computer, also only need simply carry out system recovery can repair problem to the user.
For user data backup, time and cycle that the user can own design data timed backup, guarantee in back user's the loss minimum that breaks down.If the user does not in time carry out data backup, cause operating system to damage and at this moment run into virus infections, still can carry out system recovery relievedly, and can not damage the data of D dish.At last, after system recovery is finished, user's data, even comprise that the account can not be damaged.This is because the benefit of independently bringing separately of system recovery and user data backup.
Thus, the present invention can reduce the after sale service of computer significantly, simultaneously again to having guaranteed that the computer that the user reports for repairment is not a software issue, has saved the system manufacturer after-sale service cost greatly.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
