If data recovering mark position 7 is 0, then carry out primary storage device critical data backup procedure, critical data is backed up.
Be that example is elaborated to memory device key data backup of the present invention and rejuvenation below with the hard disk.
The concrete steps of memory device key data backup process of the present invention are as follows:
S1) backup disk Master boot sector information is to data memory module 6.
S11) what logic magnetic discs analyze current system has, and this step is realized by the BIOS prior function, do not repeat them here;
S12) with Globally Unique Identifier (the Globally Unique Identifier of each logic magnetic disc correspondence, GUID) and corresponding logical device name be saved in the data memory module respectively, BIOS has the function of the logical device name of searching logic magnetic disc and correspondence thereof, does not repeat them here;
S13) the disk Master boot sector information with each logic magnetic disc is saved in the data memory module.
512 bytes of physical disk beginning are called Master boot sector, and by analyzing Master boot sector, what subregions just can know has in the disk.
A disk has only a Master boot sector.
Master boot sector is made up of 3 parts, is respectively that (Master Boot Record is MBR) with disk partition table (DPT) and magic number (0x55AA) for Main Boot Record.Saved system guidance code among the MBR, the partition information of in store disk in the partition table.Just can know that by analyzing partition table this disk has several subregions, what divisional type is.
S2) boot sector and the file system superblock with each subregion is saved in the data memory module.
S21) analyze the Master boot sector of each logic magnetic disc, infer what subregions;
Fig. 3 is a disk Master boot sector structural drawing, and shown in 3, the disk Master boot sector is made up of following 4 parts:
One, main bootstrap program (offset address 0000H--0088H), it is responsible for loading from active partition, and the operational system boot;
Two, the error message data field, offset address 0089H--00E1H is an error message, 00E2H--01BDH is 0 byte entirely.
Three, and partition table (Disk Partition Table DPT) contains 4 subregion items, offset address 01BEH--01FDH, and long 16 bytes of each subregion list item, totally 64 bytes are subregion item 1, subregion item 2, subregion item 3, subregion item 4.
Four, the end mark word, 2 byte values of offset address 01FE--01FF are end mark 55AA, if this sign error system just can not start.
MBR information takies 512 bytes altogether, and wherein, 64 bytes of offset address 01BEH--01FDH are 4 partition information tables.Partition table is positioned at 0 cylinder, 0 magnetic head, 1 sector, first partition table that begins with displacement 1BEH is as first-in-chain(FIC), indicate the physical location (xx cylinder, 0 magnetic head, 1 sector) of next partition table by the link list item in the table, same displacement 1BEH place in the sector of this position, in store the 2nd partition table, and the like, until the physical location (yy cylinder, 0 magnetic head, 1 sector) that points to last partition table.The project of each partition table takies 16 bytes, disk partition table list item structure as shown in Figure 4, the implication of concrete byte is as follows:
The 1st byte representative bootstrapping sign if the value of this byte is 80H, represents that then this subregion is active partition; If the value of this byte is 00H, represent that then this subregion is an inactive partition;
2nd, 3,4 bytes are represented initial No.1, the start sector number, start cylinder number of this subregion respectively;
The divisional type symbol of the 5th this subregion of byte representation.
The partition table of a disk has 4, because a disk has only 4 subregion list items, therefore a disk can only have 4 main partitions at most.When setting up more than 4 subregions, needs just need set up an extended partition earlier on a disk.And on an extended partition 4 subregions can only be arranged also, therefore when needs are divided a plurality of subregion, have and need on this main extended partition, divide time extended partition again, and then on inferior extended partition, divide more logical partition.When we need divide a plurality of subregion, the foundation of the circulation recurrence that comes to this and division subregion.
Therefore, judge when what subregions a disk has, need the leader record and the partition table of main boot partition of reading of recurrence and expansion boot partition.
S22) obtain partition boot sector or file system superblock, boot sector and the file system superblock with each subregion is saved in the data memory module then.
The boot sector of subregion is exactly 512 bytes of each subregion, reads 512 bytes of these subregions by each partitioned method on the traversal disk and obtains each partition boot sector, and be saved in the data memory module.
The size of file system superblock is 1024 bytes, and reference position is the 1024th byte place of subregion.Therefore, read 2048 bytes of each subregion, just can obtain the boot sector and the file system superblock of subregion, then, be saved in the data memory module.
Described file system superblock has been described the key property that is installed in the file system on the current subregion, comprises file system type, size, the size of each data block, information such as reference position.
If file system superblock information is damaged,, also can increase the workload that data are recovered greatly even the disk partition table does not damage.As long as the file system superblock is excellent, just can infer the position and the content of other parts of file system thus.So, the file system superblock also must be backed up.
Described logic magnetic disc is independent disk or Redundant Array of Independent Disks (RAID).
Fig. 6 reads process flow diagram for single hard disk boot sector of the present invention and partition information, and as shown in Figure 6, single hard disk boot sector of the present invention and partition information process of reading are as follows:
S211) read the partition table of Master boot sector;
S212) according to the 5th byte of a partition table, read divisional type;
Wherein, 00H represents that this subregion do not use; 06H and 0BH represent the main partition; 05H and 0FH represent extended partition.
S213), then in data memory module, write down the start-stop position file system superblock information of this subregion if divisional type is the main partition; Otherwise, continue;
The start position information of this subregion can obtain from the 2nd, 3,4 bytes of partition table;
The size of file system superblock is 1024 bytes, and reference position is the 1024th byte place of subregion.
S214) if divisional type is an extended partition, then in data memory module, write down this partitioned file system superblock information, and in data memory module, preserve all boot sectors of extended partition, in data memory module, write down the reference position and the number of each subregion according to the partition information table of partition boot sector;
The boot sector of subregion is exactly 512 bytes of each subregion, reads 512 bytes of these subregions by each partitioned method on the traversal disk and obtains each partition boot sector.The size of file system superblock is 1024 bytes, and reference position is the 1024th byte place of subregion.
From first subregion to the, four subregions, repeat above-mentioned steps 1211~1214, the boot sector and the partition table that read Master boot sector and expansion boot partition of recurrence, and obtain the number of all subregions of all hard disks on the computing machine and each subregion start-stop position on hard disk separately.
Fig. 5 is a memory device key packet storage format structural drawing, and as shown in Figure 5, this packet is made of following data:
Data packet length (4byte); Packet timestamp (4byte); Hard disk GUID (8byte); Hard disk logical device name (16byte); Master boot sector information (512byte); (N * 512byte), the N value is determined by the extended partition number extended partition boot sector information; Each partitioned file system superblock information (M * (1024+4) byte), the M value is determined by the subregion number.
Wherein, data packet length is used to preserve the total length of this packet; The packet timestamp is used to preserve the Time Created of this packet; Hard disk GUID and hard disk logical device name are used for the GUID and the corresponding hard disk logical device name of each hard disk of saved system; Master boot sector information is used to preserve the disk Master boot sector record of each hard disk; Extended partition boot sector information is used to preserve the partition boot sector record of the extended partition of each hard disk; Each partitioned file system superblock information be used to preserve each subregion the key property of file system, comprise file system type, size, the size of each data block, information such as reference position.
The concrete steps of memory device key data recovery procedure of the present invention are as follows:
R1), recover disk Master boot sector record according to the information in the memory device key information packet in the data memory module.
R11) according to the hard disk GUID (8byte) in the memory device key information packet in the data memory module; Hard disk logical device name (16byte); Master boot sector information (512byte) learns that the computer system that needs to recover has what disks or RAID, and according to the GUID of disk model or RAID correspondence Master boot sector information is returned on the corresponding disk.
R2), recover extended partition boot sector information and each partitioned file system superblock information according to the information in the memory device key information packet in the data memory module.
