Embodiment
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, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making under the creative work prerequisite the every other embodiment obtained, belong to the scope of protection of the invention.
Referring to Fig. 1 and Fig. 2, the invention provides a kind of network hard disk system, comprise client 10 and the service end 14 be connected with client, described service end comprises file server 141, application server 142 and the database server 143 connected successively, described file server is provided with memory module 13, this memory module is connected with data transmission port 11 and mixed-media network modules mixed-media 12, and this memory module is connected with client by mixed-media network modules mixed-media.Network hard disc is divided into service end and client, and service end mainly receives the file that service end uploads and do storage on file server.Service end also provides renaming online and edit operation of net dish file.Client realizes the monitoring of file under user PC terminal specified file catalogue and file is uploaded and the down operation of file.File server can adopt public network to be connected with described application server, and application server can adopt local area network (LAN) to be connected with database server.What file server adopted is configured to: central processing unit adopts E7-48302 8 core processors of Intel Xeon; Dominant frequency: 2.13GHz, three grades of high-speed caches; Memory size is 32G; Hard disk adopts 3, and the space size of each hard disk is 300G; The operating system adopted is: the linux enterprise version.What application server and database server adopted is configured to: the model of central processing unit is: PowerPC_POWER5; The number of processor is 8; Processor clock speed is 4.2GHZ; Memory size is 32G; Hard disk is 4, and every space is 146G; The operating system adopted is: AIX6.3.
The concrete execution mode as the present invention, described memory module comprises data cache module 131 and data memory module 132, described data cache module is DRAM, and data cache module adopts DRAM can improve exchanges data speed, and described data memory module is EEPROM.For office flexibly, client can adopt PC 101 and mobile terminal device 102, the mixed-media network modules mixed-media that memory module connects comprises wireless control module 121, by the wireless receiving and dispatching control module, with mobile terminal device, be connected, the convenient mobile terminal device that adopts, during as offices such as palmtop PC, removable computers, conveniently with network hard disc, be connected.In addition, described data transmission port comprises USB interface, ide interface and SATA interface, can conveniently have the user of authority directly by the mode copied, from network hard disc, to upload the download desired data.
Further, adopt network hard disk system as above, the Realization of Storing of network hard disk system is provided, comprise the steps:
Step 1: the file under user customer designated disk path is operated, and action type comprises: to file edited, deletion, rename, creation operation; Network hard disk system has the function of file monitor, mainly uses the file monitor object to realize the monitoring of the operations such as or deletion newly-increased to file or folder under specified path, rename, editor.After operation has occurred file or folder, by information recordings such as action types, in local data base, in addition, the user can arrange the file filter type, when monitoring, only corresponding file type is carried out to monitoring record.
Step 2: judge whether operated file is shared file, and file type can be divided into shared file and owner file;
Step 3: but judged whether to there is write permission for shared file,
If but this shared file has write permission, enter step a: amended shared file is synchronized to service end; When existing conflict, the file obtained from server and local network dish catalogue enable the processing that conflicts of conflict processing module.Concrete processing mode, carry out according to the conflict processing policy.Client produces conflict and mainly contains following several situation: as: the user logs at the A computer, after editing files, to the B computer, logs in, and now A computer editing's file synchronization does not complete, and the user will cause that at B computer downloading data data are inconsistent.
, if but this shared file has read right, enter step b: do not need amended shared file is synchronized to service end;
Step 4: the file record after being operated enters the file difference list; File monitor file that object is monitored is divided into two kinds: user self file: once the file monitor object monitors file, any operation is arranged, immediately operation note is entered in the difference list; The difference list comprises user's action type, operating time, the information such as file ID; Other user's shared files: monitored object is the file reading Share Permissions at first, if access limit enters operation note in the difference temporary table, otherwise the prompting user can not editing files; Regularly the result in file monitor is carried out to statistical analysis simultaneously, according to filename, file path, user's login ID, file operation time filter out the last operation the variance analysis result are submitted to service end from the file monitor list, and service end is according to present a paper service end or from the service end deleted file of file operation type.
Step 5: will deposit file in the file difference list according to the time ascending sort, and give ID of each file allocation;
Step 6: transmit to service end acquisition request fileinfo preparation according to the file ID in the file difference list;
Step 7: the file that needs is carried out to transfer of data carries out file locking, in order to avoid cause the file operation conflict; After the file that needs are carried out to transfer of data is locked, can not carry out any operation to the file of this locking
Step 8: in the document flow mode, carry out transfer of data; Transfer of data comprises that file is uploaded and file is downloaded.
Step 9: after the transfer of data success, data message is deleted from the file difference list.
When existing conflict, the file obtained from server and local network dish catalogue enable the processing that conflicts of conflict processing module.Concrete processing mode, carry out according to the conflict processing policy.Client produces conflict and mainly contains following several situation:
1, the user logs at the A computer, after editing files, to the B computer, logs in, and now A computer editing's file synchronization does not complete, and the user will cause that at B computer downloading data data are inconsistent.
Processing policy: before synchronously not completing, the user can not download file, locking user down operation;
2, the party A-subscriber checks and edits shared file F at the A computer, and the party B-subscriber checks and edit shared file F at the B computer simultaneously, and now party A-subscriber's synchro edit file F is to service end, and service end file F and party B-subscriber viewing files on the B computer is inconsistent;
Processing policy: after file F synchronously completes, give user B information, again whether the prompting user download file F;
3, the user downloads shared file F to local, but the local file that has had a F by name, the filename conflict; Processing policy: prompting user file name conflict;
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
