Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further details.
Said equipment is meant that all can carry out the equipment of exchanges data in the present embodiment, comprises server, desktop computer, notebook, PDA, peripheral hardware etc. and some intelligent appliances etc.The said equipment is divided into two classes, is synchronisation source with the device definition at the standard place of file synchronization, is synchronous target with the device definition for the treatment of synchronous file place.This two kind equipment can exist respectively on the different hardware devices, also can be on same hardware device.For example: synchronisation source is on desk-top computer, and target is on PDA or notebook computer synchronously; Perhaps synchronisation source and synchronously target coexist on the computing machine, but be two different catalogues or file on this computing machine.
The normative document that provides on the synchronisation source is called as synchronous documents, and what be provided with on the target synchronously will be called by synchronous documents with the file that synchronous documents is consistent.
Synchronisation source provides synchronizing function, and the synchronous documents by on synchronous documents and the synchronisation source on the synchronous target is consistent.Synchronously target is used synchronizing function, and this equipment or other and synchronisation source automatic with the file on the equipment that this equipment links to each other is consistent.
Thinking of the present invention is: select synchronous documents on synchronisation source, and the attribute information of synchronous documents is saved as journal file; On the target synchronization rules is being set synchronously; After synchronous target and synchronisation source connect, carry out synchronous operation, make by synchronous documents and upgrade automatically, promptly duplicate the synchronous documents on the synchronisation source, replace on the synchronous target by synchronous documents, thereby make and be consistent by synchronous documents and synchronous documents.
Figure 1 shows that the process flow diagram of using selection synchronous documents of the present invention.
Step 101, the user selects synchronous documents, and this synchronous documents can be a file, also can be a catalogue, may comprise sub-directory in this catalogue;
Step 102, synchronisation source read the attribute information of user-selected synchronous documents, and the attribute of described synchronous documents comprises absolute path name, relative path filename, the file amendment time of user-selected synchronous documents at least and revises type;
Step 103, synchronisation source writes journal file with the attribute information of synchronous documents, and preserves this journal file.
The journal file of synchronous documents is as shown in table 1:
| The file absolute path name | The relative path filename | The file amendment time | Revise type | |
| Record 1 | d：work | work.doc | 2003-4-2?12:20 | Create |
| Record 2 | d：work | simplestudy.doc | 2002-4-2?12:20 | Revise |
Table 1
The content of journal file comprises absolute path name, relative path filename, the file amendment time of selected synchronous documents at least and revises type.This log record adopts the recording mode of replacing, and same synchronous documents is only preserved a record in journal file, if promptly variation has taken place a synchronous documents, so directly revises this record in the journal file, and no longer creates a new record.As shown in table 1: record 1 expression user 2003-4-2 12:20 select d: work work.doc be synchronous documents, the absolute path of this synchronous documents is called d: work, the relative path file is called work.doc, owing to be that to select this document be synchronous documents to the user, therefore the file amendment time is for selecting the time of this synchronous documents, revise type for creating, if the user makes an amendment to this synchronous documents afterwards, then its file amendment time modification time that is this document is revised type for revising.Record 2 expression users revised the synchronous documents of having selected at 2002-4-2 12:20, because this synchronous documents is a catalogue, and in this catalogue sub-directory is arranged, then the absolute path of this synchronous documents is called d: work, relative path is called simple study.doc, the file amendment time is the modification time of this document, revises type for revising.
The recording mode of above-mentioned daily record also can adopt the recording mode that adds up, and the variation that is about to the each generation of each synchronous documents all is recorded in the daily record, and does not adopt the mode of replacement.
Synchronously set synchronization rules can be in the following rule one or one or more on the target:
1) synchronously on the target by synchronous documents whether with synchronisation source on file in the sub-directory keep synchronously;
2) synchronously on the target by synchronous documents whether with synchronisation source on the file that increases newly keep synchronously;
3) synchronously on the target by synchronous documents whether with synchronisation source on the file revised keep synchronously;
4) synchronously on the target by synchronous documents whether with synchronisation source on deleted file keep synchronously;
5) target has to allow the user select whether to carry out synchronous prompting in each execution synchronous operation synchronously, carries out synchronous operation again after being selected to confirm by the user, and still synchronous target automatically performs synchronous operation at every turn.
Figure 2 shows that and use the process flow diagram of judging whether synchronous documents upgrades of the present invention.
If synchronously target and synchronisation source are on different hardware devices, the step that then synchronous target and synchronisation source connect as shown in Figure 3.
Step 302, start infrared connectivity port after, execution in step 307;
Step 304, behind the startup network connection port, execution in step 307;
Step 306, behind the startup usb connecting port, execution in step 307;
If synchronously target and synchronisation source are on same hardware device, on the then synchronous target by the synchronous documents on synchronous documents and the synchronisation source by linking or alternate manner is connected.(preferably can replenish concrete
Embodiment)
When synchronous target and synchronisation source set up be connected after, safeguard a synchronous target chained list by synchronisation source, comprise the information of the synchronous documents on the user name of the synchronous target that all link to each other with this synchronisation source and the synchronisation source that this synchronous target will be used in this synchronous target chained list at least.
When synchronous target withdraws from connection, send and withdraw from message to synchronisation source, synchronisation source upgrades synchronous target chained list after receiving this message.
After synchronously target connected with synchronisation source, if target and synchronisation source are on different hardware devices synchronously, the synchronous recording table that then synchronous target is safeguarded was as shown in table 2:
| The synchronisation source file | Synchronous file destination | Lock in time | Synchronous regime | |
| Record 1 | \10.1.38.2d：workwork.doc | \11.1.38.3e：newwork.doc | 2002-4-2 12:20 | Synchronous |
| Record 2 | \10.1.38.2d：worksubmydoc.doc | \111.1.38.3e：newsubmydoc.doc | 2003-1-2 12:25 | Synchronous |
Table 2
The position of synchronisation source file, position, lock in time and the synchronous regime of synchronous file destination have been put down in writing in this synchronous recording table.The recording mode of the replacement that it adopts is only preserved a record to the synchronous recording of same synchronous documents, if promptly a synchronous documents record variation, so directly revise this record in the synchronous recording, and no longer create a new record.As shown in table 2: record 1 is illustrated in 2002-4-2 12:20, the IP address be on the synchronous target of 11.1.38.3 e: new the work.doc file once carried out synchronous operation, this synchronous operation be with the IP address be on the synchronisation source of 10.1.38.2 d: work the work.doc file be consistent, because synchronous regime for synchronous, represents that this synchronous operation runs succeeded.Record 2 is illustrated in 2003-1-2 12:25, the IP address be on the synchronous target of 11.1.38.3 e: new sub the mydoc.doc catalogue once carried out synchronous operation, this synchronous operation be with the IP address be on the synchronisation source of 10.1.38.2 d: content in the work catalogue be consistent, because its synchronous regime for synchronous, represents that then this synchronous operation also runs succeeded.If certain synchronous operation is success not, its synchronous regime then is recorded as not synchronous.
After synchronously target connected with synchronisation source, if target and synchronisation source are on same hardware device synchronously, the synchronous recording table that then synchronous target is safeguarded was as shown in table 3:
| The synchronisation source file | Synchronous file destination | Lock in time | Synchronous regime | |
| Record 1 | \10.1.38.2d：workwork.doc | \10.1.38.2e：newwork.doc | 2002-5-2 12:20 | Synchronous |
| Record 2 | \10.1.38.2d：worksubmydoc.doc | \10.1.38.2e：newsubmydoc.doc | 2003-3-2 12:25 | Synchronous |
Table 3
The record 1 of table 3 is illustrated in 2002-5-2 12:20, the IP address be on the synchronous target of 10.1.38.2 e: new the work.doc file once carried out synchronous operation, this synchronous operation be with the IP address be on the synchronisation source of 10.1.38.2 d: work the work.doc file be consistent, because synchronous regime for synchronous, represents that this synchronous operation runs succeeded.Record 2 is illustrated in 2003-3-2 12:25, the IP address be on the synchronous target of 10.1.38.2 e: new sub the mydoc.doc catalogue once carried out synchronous operation, this synchronous operation be with the IP address be on the synchronisation source of 10.1.38.2 d: content in the work catalogue be consistent, because its synchronous regime for synchronous, represents that then this synchronous operation also runs succeeded.If certain synchronous operation is success not, its synchronous regime then is recorded as not synchronous.
If synchronously target and synchronisation source on same hardware device and this equipment do not surf the Net, then the default IP address of this equipment is 127.0.0.1.
From the above, identical as the IP address in the synchronous file destination with the IP address on the synchronisation source file, synchronisation source and synchronously object representation is on a hardware device then, otherwise they are on different hardware devices.
The recording mode of table 2 table 3 also can adopt the recording mode that adds up, and the variation that is about to the each generation of each synchronous documents all is recorded in the synchronous recording, and does not adopt the mode of replacement.
Figure 4 shows that the process flow diagram of using execution synchronous operation of the present invention.
Step 405 judges whether met synchronization rules by synchronous documents on the synchronous target, if then execution in step 406, otherwise finishes synchronous operation;
Step 406 is duplicated the synchronous documents on the synchronisation source, replace on the synchronous target by synchronous documents;
Step 407 behind the renewal synchronous recording, finishes synchronous operation.
Above-described embodiment all be with the file modifying time for whether upgrading or the basis of synchronous operation, certainly, size that also can file, or with file modifying time and size for whether upgrading or the basis of synchronous operation.
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 made, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
