Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
During file is stored storage device, in addition to the file data that storage gets, also need to record the file index information that these file datas are corresponding, in order to complete the increasing to file data by these file index information, delete, look into, the operation such as change.
After device power, file system related content can be loaded in device memory, when file data storage updates (write updates), first can revise the file index information of record in the file system of device memory.Subsequently, the file system in internal memory can be written back to the index information district of storage device (hard disk) by equipment.
The embodiment of the present invention is configured with at least two index information district for storing the index information of file., file index information can be written in the index information district of correspondence as successively write or intersect to come write-back, random write etc. according to certain rule.During whole write-back, as long as ensureing the most not occur abnormal, follow-up can with do not occur abnormal index information district content update other content in index information district of exceptions occurs.
Specifically referring to Fig. 1, be the schematic flow sheet of a kind of file information processing method in the embodiment of the present invention, the described method of the embodiment of the present invention can be applicable in Miscellaneous Documents system, and it specifically can be performed by a processor, and concrete, described method includes:
S101: when detecting to memory write-back file index information, determine the file index information treating write-back.
During certain file stores memorizer, file system may require that and is periodically written back in hard disk by the related data of this document in internal memory, when reaching time interval requirement or the write-back time point of write-back, can be from internal memory to the relevant information of memory write-back this document, including file index information, memorizer can be common mechanical hard disk, can realize the SSD (SolidStateDrives, solid state hard disc) etc. of ultrahigh speed storage.
In storing process, in internal memory, the file index information about this document can update, and file index information can be the information such as the storage address of each data block block of this document, filename, establishment time.Determine when the file index information of write-back, can only determine the part content being updated, in order to reduce write-back expense.
S102: the file index information determined is written at least two index information district configured in which memory.
Configure two or more index information districts the most in which memory, for the file index information determined, need to be respectively written into two or more index information districts of configuration.
Specifically can be according to preset writeback policies write-back file index information, preset writeback policies comprises the steps that in the index information district that the file index information determined is written to correspondence successively.As a example by including Liang Ge index information district, when needs write file index information, first file index information is written to the first index information district, after completing, then file index information is written to the second index information district.Wherein, if occurring abnormal when to the second index information district write file index information, such as device looses power, the second index information district all of file index information may be lost, but the file index information in the first index information district the most all exists.And if occurring extremely, causing the file index information dropout in the first index information district, but in a upper write back cycle, the file index information being written to the second index information district there is also, do not destroyed during being written to the first index information district.It should be noted that, occurring abnormal to the first index information district write file index information, still can lose the data of this write-back, but the file index information lost is the most few, impact on the file data of storage is little, does not more have the situation that whole dish data all cannot be recovered.When existence three and above index information district, identical reasoning can be made.
Concrete, preset writeback policies can also be back and forth specifically writeback policies.Same as a example by having Liang Ge index information district, writeback policies is that number of times based on write-back performs back and forth, during n-th write-back, if N is odd number, file index information is written to the first index information district, and if N is even number, then write the second index information district.Can also more efficiently avoid file index information dropout, the situation that data all cannot be recovered in the case.
Preset writeback policies can also be: be respectively written into each index information district simultaneously；Or according to random order to each index information district write file index information；Or for selecting data volume therein two or more index information districts less than threshold value, to write file index information.
Method described in the embodiment of the present invention is also based on the applied environment being presently in, and selects different writeback policies.Concrete, if be detected that applied environment be first kind applied environment (such as: the applied environment of the high speed storing of 720P video), the writeback policies then used includes first kind writeback policies, as noted above writes successively according to order, random write, selection data volume therein be less than the strategy such as two or more index information district write-backs of threshold value；And if be detected that applied environment be Equations of The Second Kind applied environment (such as: the applied environment of the ultrahigh speed of 4K video storage), then use Equations of The Second Kind writeback policies, as noted above come writeback policies.
The embodiment of the present invention is by configuring two or more index information districts, introduce secondary or repeatedly write, can preferably ensure when write-back occurs abnormal that file index information in an at least index information district will not be lost, more efficiently avoid index information to lose, and the problem that whole dish data cannot be recovered, can preferably ensure not have the loss of heap file or damage.
Refer to Fig. 2 again, it it is the schematic flow sheet of the another kind of file information processing method of the embodiment of the present invention, the described method of the embodiment of the present invention can be applicable in Miscellaneous Documents system, it specifically can be performed by a processor, the embodiment of the present invention illustrates as a example by there is Liang Ge index information district, including three or during above index information district, write-back processing procedure refers to the processing mode in Liang Ge index information district, and described method specifically includes:
S201: when detecting to memory write-back file index information, determine the file index information treating write-back.
At certain file storing process, in internal memory, the file index information such as the position of the fragment of such as this document data block block in memory can be updated, and described S201 only can will occur the index information updated to be defined as treating the file index information of write-back.After determining the file index information treating write-back, i.e. the file index information that writes to the first index information district and the second index information district of triggering following.
S202: when detecting to the first index information district write file index information, the write state in the first index information district is set for writing beginning state；
Wherein, arrange the write state in the first index information district specifically to may include that and start mark for described first index information district configurable write or be set to write by the index mark of described first index information district association and start mark.The most newly configured one write start mark or be set to write beginning by existing mark.
Specifically can processor detect from internal memory transmission until write-back file index information time, i.e. determine and be currently needed for the first index information district write file index information.
S203: the file index information determined is written in described first index information district；The file index information treating write-back will determined in S201 is written in described first index information district.
S204: after detecting that the write of the file index information to the first index information district terminates, be updated to write complete state by the write state in the first index information district；
Wherein, the write state in the first index information district is updated to write complete state include: complete mark for described first index information district configurable write or be set to write complete mark by the index mark of described first index information district association.It is newly configured one of described first index information district and writes complete mark, start to identify corresponding with writing, or be set to write complete by the described mark being set to write beginning.
S205: when detecting to the second index information district write file index information, the write state in the second index information district is set for writing beginning state；
Wherein, arrange the write state in the second index information district specifically to may include that and start mark for described second index information district configurable write or be set to write by the index mark of described second index information district association and start mark.It is newly configured one of described second index information district to write and start mark, or is set to write beginning by existing mark.
Can be the most specifically processor detect from internal memory transmission until write-back file index information time, determine that needs are to the first index information district write file index information.Or can be to be updated to write complete state in the state the first index information district being detected, or when write-back file index information has been completely written to described first index information district, determine that needs are to the second index information district write file index information.
S206: the file index information determined is written in described second index information district；The file index information treating write-back will determined in S201 is written in described second index information district.
S207: after detecting that the write of the file index information to the second index information district terminates, be updated to write complete state by the write state in the second index information district；
Wherein, the write state in the second index information district is updated to write complete state include: complete mark for described second index information district configurable write or be set to write complete mark by the index mark of described second index information district association.It is newly configured one of described second index information district and writes complete mark, or be set to write complete by the mark being set to write beginning.
Concrete, above-mentioned S202 to S204 first can carry out write operation to the first index information district to write operation and the described S205 to S207 in the first index information district to the write operation in the second index information district, then the write operation to the second index information district is performed, that is: after the described file index information determined has been completely written to described first index information district, perform in described the second index information district file index information determined being written to and configuring in which memory.
It should be noted that, having three or during above index information district, writeback policies can more flexible configure, such as, when there being 5 index information districts, write-back successively and write-back combination simultaneously i.e. first can be carried out write-back to first, second, third index information district simultaneously, the most successively the 4th index information is carried out after write-back completes write-back, then the 5th index information district is carried out write-back.
After described file storage terminates, and after its relevant file index information is the most all written back in memorizer, the described file index information back for this document of the embodiment of the present invention completes.The step that can continue through above-mentioned S201 to S207 continues executing with for alternative document write back operations of relative index information in storing process.
Before index information district write file index information, specifically can be when initial device power-up initializes, or when determining until the file index information of write-back, the described method of the embodiment of the present invention can also include: detection applied environment, identifying storage speed grade, described storage speed grade is to determine based on the speed requirement writing data in described memorizer；I.e. need to judge the applied environment that described memorizer is in such as 720P video high speed storing, be in the applied environment of the ultrahigh speed storage of such as 4K video.After identifying storage speed grade, according to the storage speed hierarchical selection writeback policies identified, specifically can select from preset writeback policies.When identifying as high speed storing speed class, S201 to S207 described in the strategy execution of write-back successively can be selected.
The embodiment of the present invention is by writing the modes such as file index information successively in Liang Ge index information district, preferably ensure that the file index information in an at least index information district will not be lost, more efficiently avoid index information to lose, and the problem that whole dish data cannot be recovered, particularly in the high-speed memory systems such as mechanical hard disk, can preferably ensure not have the loss of heap file or damage.
Refer to Fig. 3 again, it it is the schematic flow sheet of another file information processing method of the embodiment of the present invention, the described method of the embodiment of the present invention can be applicable in Miscellaneous Documents system, it specifically can be performed by a processor, the embodiment of the present invention illustrates as a example by there is Liang Ge index information district, including three or during above index information district, processing procedure refers to the processing mode in Liang Ge index information district, and described method specifically includes:
