Abstract

A device for collecting history of data transfer includes a transfer-history-extraction unit which extracts transfer-history information from data subjected to data transfer, and a service-management unit which stores the transfer-history information together with a processing result indicative of either a proper completion of the data transfer or an improper completion of the data transfer.

Claims

1. A device for collecting history of data transfers, comprising:

a transfer-history-extraction unit which extracts transfer-history information from data subjected to data transfer each time the data transfer is performed, the extracted transfer-history information being separate from the data subjected to data transfer;

a service-management book; and

a service-management unit which newly registers the extracted transfer-history information in the service-management book if transfer-history information about said data transfer is not yet registered in the service-management book, and stores a processing result indicative of either a proper completion of the data transfer or an improper completion of the data transfer together with the extracted transfer-history information registered in the service-management book, whereby said service-management book stores the processing result for each of said data transfers.

2. The device as claimed in claim 1, wherein the data subjected to data transfer includes data to be transferred from said device to another device connected thereto.

3. The device as claimed in claim 1, wherein the data subjected to data transfer includes data to be transferred to said device from another device connected thereto.

4. The device as claimed in claim 1, wherein said service-management unit registers the transfer-history information about a given data transfer in the service-management book if the transfer-history information about the given data transfer is not registered in the service-management book.

5. The device as claimed in claim 1, further comprising:

a search unit, wherein the transfer-history information includes a destination, a type of data transfer, and a file name, which have a group ID attached thereto, and said search unit searches in the transfer-history information for an entry having a specified group ID when a search request is made with the specified group ID.

6. The device as claimed in claim 1, further comprising:

a search unit which searches in the transfer-history information for an entry having a specified file name when a search request is made with the specified file name.

7. The device as claimed in claim 6, wherein a request for retransmission is made when the specified processing result indicates the improper completion of the data transfer.

8. The device as claimed in claim 1, further comprising:

a search unit which searches in the transfer-history information for an entry stored together with a specified processing result when a search request is made with the specified processing result.

9. A computer-readable medium having a program embodied therein for causing a computer to collect history of data transfers, said program comprising:

a transfer-history-extraction unit which extracts transfer-history information from data subjected to data transfer each time the data transfer is performed, the extracted transfer-history information being separate from the data subjected to data transfer;

a service-management book; and

a service-management unit which newly registers the extracted transfer-history information in the service-management book if transfer-history information about said data transfer is not yet registered in the service-management book, and stores a processing result indicative of either a proper completion of the data transfer or an improper completion of the data transfer together with the extracted transfer-history information registered in the service-management book, whereby said service-management book stores the processing result for each of said data transfers.

10. The computer-readable medium as claimed in claim 9, wherein the data subjected to data transfer includes data to be transferred from said computer to another computer connected thereto.

11. The computer-readable medium as claimed in claim 9, wherein the data subjected to data transfer includes data to be transferred to said computer from another computer connected thereto.

12. A system for managing history of data transfers, comprising:

a data-storage unit;

a transfer-history obtaining unit which obtains transfer-history information each time a data transfer service is performed to transfer a file, the transfer-history information identifying the data-transfer service, the obtained transfer-history information being separate from data subjected to the data-transfer service;

a service-management book; and

a service-management unit which newly registers the obtained transfer-history information in the service-management book if transfer-history information about said data-transfer service is not yet registered in the service-management book, and stores, in said data-storage unit, a processing result indicative of either a proper completion of the data-transfer service or an improper completion of the data-transfer service together with the obtained transfer-history information registered in the service-management book, whereby said service-management book stores the processing result for each of said data-transfer services.

13. The system as claimed in claim 12, wherein the processing result includes information indicative of data that was not transferred within the file because of the improper completion of the data-transfer service.

14. The system as claimed in claim 13, wherein the information indicative of the data that was not transferred within the file identifies the data that was not transferred within the file by identifying data that was successfully transferred within the file.

15. The system as claimed in claim 13, wherein the processing result further includes a date and time of a last update with regard to the file.

16. The system as claimed in claim 12, wherein the transfer-history information includes information indicative of whether an operation of data retransmission that resumes data transfer from halfway through the data-transfer service is available, and, if the operation is indicated to be available, the processing result includes information indicative of data that was not transferred within the file because of an improper completion of the data-transfer service.

17. The system as claimed in claim 12, further comprising:

first check means for checking if the transfer-history information includes an entry of a requested service when the requested service is requested;

second check means for checking whether the processing result associated with the entry of the requested service indicates the improper completion of data transfer; and

data-transfer processing means for performing data transfer of the requested service if said second check means finds that the requested service improperly completed.

18. The system as claimed in claim 17, wherein the processing result includes information indicative of data that was not transferred within the file, and said data-transfer processing means transfers the data that was not transferred within the file when said second check means finds that the requested service improperly completed.

19. The system as claimed in claim 17, wherein the processing result includes information indicative of a date and time at which the requested service improperly completed, and said data-transfer processing means transfers an entirety of the file if the file to be transferred was updated since the indicated date and time.

20. A computer-readable medium having a program embodied therein for causing a computer to manage history of data transfers, said program comprising:

a transfer-history obtaining unit configured to obtain transfer-history information each time a data transfer service is performed to transfer a file, the transfer-history information identifying the data-transfer service, the obtained transfer-history information being separate from data subjected to the data transfer service;

a service-management book; and

a service-management unit configured to newly register the obtained transfer-history information in the service-management book if transfer-history information about said data transfer service is not yet registered in the service-management book, and to store, in a memory storage, a processing result indicative of either a proper completion of the data-transfer service or an improper completion of the data-transfer service together with the obtained transfer-history information registered in the service-management book, whereby said service-management book stores the processing result for each of said data transfer services.

21. The computer-readable medium as claimed in claim 20, further comprising:

a first check unit configured to check if the transfer-history information includes an entry of a requested service when the requested service is requested;

a second check unit configured to check whether the processing result associated with the entry of the requested service indicates the improper completion of data transfer; and

a data-transfer unit configured to perform data transfer of the requested service if said second check unit finds that the requested service improperly completed.
