It is above-mentioned that synchronize rear storage address refer to the position for placing file to be synchronized.For example, synchronize rear storage address be B storage in,
Or it synchronizes under the userdata file directorys that rear storage address is B storages.
Optionally, in an alternative embodiment of the invention, method of the present invention may also include：
Obtain it is described synchronize rear storage address after, judge that the capacity for synchronizing the affiliated memory space of rear storage address is big
It is small whether to meet preset capacity condition；If so, executing step S30.
Wherein, it can be the total size that amount of capacity is more than file to be synchronized that amount of capacity, which meets preset capacity condition,
Either the difference of amount of capacity and the size of file to be synchronized is more than preset capacity.Specifically, preset capacity can be according to need
It sets.
It is stored for B for example, synchronizing rear storage address, then the amount of capacity for synchronizing the affiliated memory space of rear storage address is B
The amount of capacity of storage.Alternatively, synchronizing the userdata file directorys that rear storage address is B storages, then rear storage address is synchronized
The amount of capacity of affiliated memory space is similarly the amount of capacity of B storages.When the amount of capacity of B storages is more than file to be synchronized
Total size when, just execute step S30, i.e., just execute carry out subsequent synchronisation file operation.
It through this embodiment, can be to avoid, because Insufficient disk space occurs abnormal, increasing file synchronization after file synchronization
Success rate.
Optionally, in an alternative embodiment of the invention, method of the present invention may also include：
Obtain it is described synchronize rear storage address after, judge described to synchronize whether rear storage address is default storage address；
If so, executing step S30.
Above-mentioned default storage address can be preset storage address.
In the present embodiment, when carrying out file synchronization, will not by the file except file synchronization to preset range,
It ensure that safety when file synchronization.
S30 is synchronized the file that the file to be synchronized includes from storage address before described synchronize by RSYNC instructions
Rear storage address is synchronized to described.
Wherein, teledata synchronization may be implemented in above-mentioned RSYNC instructions, and the detailed description of RSYNC can be from the prior art
Middle acquisition, details are not described herein again.
Specifically, RSYNC, which can carry out increment synchronization, either carries out full dose synchronization.That is, by file to be synchronized
All Files synchronize, or the delta file in file to be synchronized is synchronized.
Since RSYNC instructions have the characteristics that be rapidly performed by file transmission, in the present embodiment, using RSYNC
Instruction carries out file synchronization, improves the speed of file synchronization, realizes the purpose of rapid file synchronization.When apply high-volume
When in the case of file transmission, it is transmitted compared to using others instruction, can greatly saves transmission time.
Optionally, in other embodiments of the present invention, synchronization folder can also first be treated before executing step S30
It is encrypted, or the file for including in file to be synchronized is encrypted, then carried out file together by RSYNC instructions
Step, to improve the safety during file synchronization.
S40, acquisition synchronize rear file, count the fileinfo for synchronizing rear file clip pack and containing, obtain the second file
Inventory.
It is wherein, above-mentioned that synchronize rear file be the file after Folder synchronizing to be synchronized.
It is above-mentioned count to synchronizing the fileinfo that rear file clip pack contains specifically may include but be not limited to：To synchronizing hereinafter
The quantity for the file that part clip pack contains, the title of file, the type of file, one or more information such as modification time of each file
It is counted.
In the specific implementation, which information of the content statistics for including to file before synchronizing, after synchronization can also
Carry out same Information Statistics.
For example, the first lists of documents include the quantity of the title and file of file, then after acquisition synchronizes after file,
Statistics synchronizes the title for the file that rear file clip pack contains and the quantity of file, i.e. includes to synchronize rear file in the second lists of documents
The title for the file for including in folder and the quantity of file.
S50 matches first lists of documents with second lists of documents, it is determined whether it is same to complete file
Step.
Wherein, the first lists of documents are subjected to matching for determining in synchronous preceding file to be synchronized with the second lists of documents
Including file and the file for including in synchronous rear file to be synchronized it is whether consistent, if unanimously, determine complete file synchronization.
If the first lists of documents and the file name that the second lists of documents include are all consistent, but have a small number of file sizes not
Together, it can also determine that file synchronization is completed.Meanwhile can by the first lists of documents with file name among the second lists of documents
Identical, the different file of file size is shown.Due at this point, having been completed most file transmission, only part text
The size of part may be different, therefore it is fully synchronized to notify that the mode of display allows user to know which file does not have, to use
Family checks whether to need again will be identical as file name among the second lists of documents in the first lists of documents, and file size is different
File synchronize.
It, can will be every in lists of documents specifically, when being matched the first lists of documents with the second lists of documents
One is matched one by one.
For example, the file name progress for including with the second lists of documents by the file name that the first lists of documents include
Match, whether the title to determine file is consistent.Meanwhile the number of the quantity and the second file for the file for by the first lists of documents including
Amount is matched, and whether the quantity to determine file is consistent.If consistent, determine and complete file synchronization.
For another example, by the file total size and total number of files amount and the file in the second lists of documents in the first lists of documents
Total size is matched with total number of files amount, if unanimously, the file name in the first lists of documents, file size, file are created
Build the time is matched with the file name in the second lists of documents, file size, file creation time, if unanimously, determining text
Part synchronously completes.
In the present embodiment, by after synchronizing the second lists of documents with it is synchronous before the first lists of documents carry out
Match, can more accurately position whether file synchronization is fully completed, goes to check whether file synchronizes one by one without user
It completes, the time of user can be saved.Especially when high-volume file is transmitted, since the quantity of file transmission is more,
The method carries out file synchronization through the invention, can greatly reduce the time of manual review, and timely positioning synchronous
Incomplete file is conducive to timely feed back the effect of file synchronization.
Meanwhile in other embodiments of the present invention, during file synchronization, if having, file is of the same name, can pass through following step
Suddenly it is handled：
(1) in synchronizing process, if described synchronize the first file for including in rear storage address and the file to be synchronized
The second file for including in folder is of the same name, obtains the first modification time of first file and the second of second file is repaiied
Change the time.
(2) if the first modification time compares the second modification time closer to present system time, not by first text
Part is covered.
(3) if the second modification time compares the first modification time closer to present system time, by first file
It is covered.
In general, each file has its creation time, if being modified to file, file has its modification time, modification
Time belongs to one in the attribute information of file.
If file is modified, the modification time of file changes therewith, while the content of file may be updated.
Therefore, in the present embodiment, if during file synchronization, file situation of the same name is encountered, when can be by the modification of file
Between determine whether to cover file.So that in synchronizing process, newest file will not be override by old file.
Meanwhile in other embodiments, it can also judge whether the file type of the first file is specified type.
If the file type of the first file is not specified file type, and when the first modification time is compared to the second modification
Between closer to present system time, carry out file covering.If the file type of the first file is specified file type, no matter
Whether the first modification time, closer to present system time, does not cover first file compared to the second modification time
Lid.
Pass through embodiment of above so that in a certain class file immediately in the case of of the same name, can also quickly it synchronize,
Without being reminded.
Meanwhile in the specific implementation, no matter covering either do not cover file of the same name, can by the daily record of synchronous documents into
Row is exported and is marked, so that user quickly understands not fully synchronized file, and then is triggered synchronic command again and is carried out file
It is synchronous, save file synchronization the time it takes.
In other embodiments of the present invention, during file synchronization, if occur it is abnormal, can be by following steps at
Reason：
(1) it is abnormal when if synchronous, obtains abnormal cause；
(2) if abnormal cause is that network connection is abnormal, from obtained in synchronization log in the file to be synchronized together
Step file；
(3) determine described in the file to be synchronized that file other than synchronous documents is in the file to be synchronized
Non- synchronous documents；
It (4), will be in the file to be synchronized by RSYNC instructions if receiving the normal notification message of network connection
Non- synchronous documents, which are synchronized to, described synchronizes rear storage address.
In the specific implementation, the abnormal cause that outflow occurs in the process can be obtained by the function to catch the exception.
Above-mentioned synchronization log is the log information for recording file synchronization process.For example, can be in synchronizing process
The title record of file will be transmitted, then from the synchronous documents that can be obtained in the synchronization log in file to be synchronized.
Meanwhile synchronization log can also print the relevant information of all synchronous documents during file synchronization,
Exception during alloing relevant staff easily to understand file synchronization and know synchronized result.
For example, if it includes 26 files to amount in file to be synchronized, what is wherein recorded in synchronization log has synchronized
File is tri- files of A, B, C, it is determined that in file to be synchronized among 26 files other than tri- files of A, B, C
File be non-synchronous documents.
When network connection exception, it can actively be connected at interval of a period of time and synchronize depositing belonging to rear storage address
Storage, when successful connection feedback message, it may be determined that receive the normal notification message of network connection.At this point, passing through RSYNC
Non- synchronous documents in file to be synchronized are synchronized to by instruction synchronizes rear storage address.
In the present embodiment, abnormal processing is added, improves fault-tolerant processing ability when exception occurs, is further promoted
The reliability of file transmission success.
Further, in other embodiments of the present invention, if abnormal cause is memory space inadequate, prompting message is sent out.
When being reminded, can be reminded to relevant staff by way of popping up prompting frame.
Through the embodiment of the present invention, it can be abnormal in file synchronization, and the exception can not actively be passed by again
Timely relevant staff is reminded to remind in the case of being totally lost into file synchronization, so that the problems in file synchronization process
It can find to solve in time in time, shorten the time for completing file synchronization.
File synchronisation method provided by the invention obtains file to be synchronized, the file for including to the file to be synchronized
Information is counted, and the first lists of documents are obtained；Obtain before the Folder synchronizing to be synchronized storage address with it is synchronous after store
Address；File that the file to be synchronized includes is synchronized to from storage address before described synchronize by RSYNC instructions described
Synchronize rear storage address；Acquisition synchronizes rear file, counts the fileinfo for synchronizing rear file clip pack and containing, and obtains the second text
Part inventory；First lists of documents are matched with second lists of documents, it is determined whether complete file synchronization.Due to
Instructed by RSYNC and carry out data synchronization, and after synchronizing by before Folder synchronizing to be synchronized the first inventory with it is to be synchronized
The second inventory after Folder synchronizing is matched, the case where so as to obtain file synchronization, to determine whether synchronizing success.
Therefore it is not necessarily to Attended mode when high-volume file transmits, goes to check synchronized result one by one without manpower, it is big to realize raising
