Embodiment
Technical scheme in the present invention is understood better in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.
In order to realize the data recovering Master boot sector when the data of Master boot sector are destroyed in time, the embodiment of the present invention provides a kind of data reconstruction method of Master boot sector, the method can be, but not limited to be applied in computing machine or virtual machine, the flow process of the method as shown in Figure 1, performs step as follows:
S11: detect Master boot sector and whether preserve the first setting identification.
In the normal situation of the data of Master boot sector, first setting identification is kept in Master boot sector, once the data of Master boot sector are destroyed, first setting identification is just destroyed, therefore, periodic detection Master boot sector whether can preserve the first setting identification, also can detect Master boot sector aperiodically and whether preserve the first setting identification, thus determine whether the data of Master boot sector are destroyed according to whether preserving the first setting identification in Master boot sector.
Alternatively, detect Master boot sector with setting cycle and whether preserve the first setting identification, this setting cycle can set according to actual needs, such as, is set as 1 hour, 2 hours, 2.5 hours, 3 hours etc.; First setting identification also can set according to actual needs, can be setting character, setting symbol, end mark etc.
S12: if Master boot sector does not preserve the first setting identification, then detect the Backup Data whether reserved storage space preserves Master boot sector.
Master boot sector does not preserve the first setting identification, two kinds of situations may be there are, one is that Master boot sector not yet uses, Master boot sector never preserved data, another kind is that the data of Master boot sector are destroyed, in order to be confirmed to be which kind of situation, also need to check whether reserved storage space preserves the Backup Data of Master boot sector further, and then confirm whether the data of Master boot sector are destroyed.
S13: if reserved storage space preserves the Backup Data of Master boot sector, then determine that the data of Master boot sector are destroyed.
If reserved storage space preserves the Backup Data of Master boot sector, illustrate that Master boot sector is brought into use, but there is no again the first setting identification, so just can determine that the data of Master boot sector are destroyed.
S14: the data recovering Master boot sector according to the Backup Data of reserved storage space.
After determining that the data of Master boot sector are destroyed, the Backup Data of timely acquisition reserved storage space recovers the data of Master boot sector, the mode recovered has a variety of, and the concrete Backup Data of reserved storage space directly can being kept in Master boot sector realizes.
In the program, whether periodic detection Master boot sector preserves the Backup Data whether the first setting identification and reserved storage space preserve Master boot sector, if but Master boot sector does not preserve the Backup Data that the first setting identification reserved storage space preserves Master boot sector, then determine that the data of Master boot sector are destroyed, and the data of Master boot sector are recovered in time according to the Backup Data of the Master boot sector of reserved storage space preservation, thus can when detecting that the data of Master boot sector are destroyed, the data of timely recovery Master boot sector, guarantee normal process customer service.
Optionally, after S11, if Master boot sector preserves the first setting identification, then in reserved storage space, back up the data of Master boot sector, obtain the Backup Data of Master boot sector.
If Master boot sector preserves the first setting identification, illustrate that the data of boot sector are normal, at this moment can back up in the data of reserved storage space to Master boot sector, all the data of Master boot sector are once backed up when determining that Master boot sector preserves the first setting identification at every turn, when can guarantee that the data of Master boot sector are destroyed, recover the data of Master boot sector as much as possible with up-to-date Backup Data.
Reserved storage space can obtain by again carrying out subregion to disk, also can adopt the existing subregion in disk, below to adopt the existing subregion of disk to be described, is illustrated in figure 2 the existing partitioned organization figure of a disk.Wherein, before disk, 4K is challenge lock region, end is reserved storage space, and the size of reserved storage space is disk size * 8 – 8, and unit is sector, such as, the disk of 10G, its reserved storage space size is 10*8 – 8=72 (sector), and the disk of virtual machine is the subregion distributing to virtual machine use, visible at virtual machine, and 4K challenge lock and reserved storage space are all to virtual machine hides.The first sector of reserved storage space is metadata sector, do not preserve the Backup Data of Master boot sector, be used for the details of Backup Data of minute book disk Master boot sector, comprise quantity, the current nearest alternate sector etc. of the Backup Data that whether this disk preserves the Backup Data of Master boot sector, most multipotency is preserved.Second sector of reserved storage space is used for last sector, as backup space, depositing the Backup Data of Master boot sector.
In reserved storage space, back up the data of Master boot sector, obtain the Backup Data of Master boot sector, detailed process is: whether the data of comparison Master boot sector are identical with Backup Data up-to-date in reserved storage space; If the data of Master boot sector are different from Backup Data up-to-date in reserved storage space, then in reserved storage space, back up the data of Master boot sector, backup mode can be incremental backup or full backup, obtains the Backup Data of a Master boot sector.If the data of Master boot sector are identical with Backup Data up-to-date in reserved storage space, then the data of Master boot sector are not backed up in reserved storage space.
The up-to-date Backup Data of Master boot sector can be only preserved in reserved storage space, also the Backup Data that not homogeneous (such as the backup of each setting cycle once) backs up can be preserved, preservation from second sector of reserved storage space, when reserved storage space whole occupied time, up-to-date a Backup Data is replaced the oldest a Backup Data, thus realizes the Backup Data preserving each setting cycle of Master boot sector in reserved storage space circulation.
Correspondingly, recover the data of Master boot sector in above-mentioned S14 according to the Backup Data of reserved storage space, detailed process is: obtain the first Backup Data from reserved storage space, and the first Backup Data is the Backup Data that up-to-date Backup Data or user determine; The first Backup Data obtained is replaced the data of Master boot sector.
Alternatively, once determine that the data of Master boot sector are destroyed, the last Backup Data can be obtained from reserved storage space, recover the data of Master boot sector according to the Backup Data of the last time.
Alternatively, if reserved storage space preserves many parts of Backup Datas, can a Backup Data (not necessarily the last Backup Data) be selected to recover the data of Master boot sector in many parts of Backup Datas.
The specific implementation recovering the data of Master boot sector is: the data of the Backup Data obtained being replaced Master boot sector, thus realizes the data recovering Master boot sector.

S32: detect the Backup Data whether reserved storage space preserves Master boot sector, if reserved storage space preserves the Backup Data of Master boot sector, performs S33; If reserved storage space does not preserve the Backup Data of Master boot sector, perform S35.
Master boot sector is not preserved and is terminated mark, two kinds of situations may be there are, one is that Master boot sector not yet uses, Master boot sector never preserved data, another kind is that the data of Master boot sector are destroyed, in order to be confirmed to be which kind of situation, also need to check whether reserved storage space preserves the Backup Data of Master boot sector further, and then confirm whether the data of Master boot sector are destroyed.
S33: determine that the data of Master boot sector are destroyed, perform S34.
If reserved storage space preserves the Backup Data of Master boot sector, illustrate that Master boot sector is brought into use, but do not terminate again mark, so just can determine that the data of Master boot sector are destroyed.
S34: obtain the first Backup Data from reserved storage space, replaces the data of Master boot sector by the first Backup Data obtained.
First Backup Data is the Backup Data that up-to-date Backup Data or user determine.
S35: Master boot sector not yet uses, not according to the data of the date restoring Master boot sector in reserved storage space.
Now may there be data in reserved storage space, also may there is no data.
S36: whether the data of comparison Master boot sector are identical with Backup Data up-to-date in reserved storage space, if the data of Master boot sector are different from Backup Data up-to-date in reserved storage space, performs S37; If the data of Master boot sector are identical with Backup Data up-to-date in reserved storage space, perform S38.
S37: the data backing up Master boot sector in reserved storage space, obtains the Backup Data of Master boot sector.
S38: the data of Master boot sector are not backed up in reserved storage space.
In the program, whether periodic detection Master boot sector is preserved and is terminated mark and whether reserved storage space preserves the Backup Data of Master boot sector, if but Master boot sector is not preserved terminate mark the Backup Data of reserved storage space preservation Master boot sector, then determine that the data of Master boot sector are destroyed, and the data of Master boot sector are recovered in time according to the Backup Data of the Master boot sector of reserved storage space preservation, thus can when detecting that the data of Master boot sector are destroyed, the data of timely recovery Master boot sector, guarantee normal process customer service.
