Abstract

A computer unit with excellent backup function is realized. A backup operation system is set, and based on the setting, a data file under editing or the like is saved in a backup section. The backup operation system is distinguished through existence of execution of a backup operation, execution timing of the backup operation, an object to be backed up, a backup destination, and the like. This prevents data loss in the case where a computer unit is hanged, or in the case where trouble of the computer unit, crash of a terminal side data storage section, or the like occurs.

Claims

1. A computer system comprising a computer unit and a removable recording medium removably loaded to the computer unit,

wherein the removable recording medium comprises:

a record medium main body; and

an information recording area provided in the recording medium main body;

wherein backup identification information indicating one or a plurality of backup systems is recorded in the information recorded area; and

wherein the computer unit comprises;

a data processor for processing a data file;

a detector for detecting the backup identification information for the removable recording medium; and

a controller for backing up the data file processed by the data processor with a backup system based on a detection result of the detector.

2. A computer system according to claim 1, wherein:

the computer unit further comprises a storage period specifying part for specifying a storage period of the backup data; and

wherein the controller saves the data file during the storage period specified by the storage period specifying part.

3. A computer system according to claim 2, wherein the computer unit further comprises an accounting part for executing different accounting according to the backup system by the controller.

4. A computer system according to claim 1, wherein the controller deletes the backed up data file when processing with the data file by the data processor is ended.

5. A computer unit, comprising:

a detector for detecting, from a removable recording medium in which backup identification information indicating one of a plurality of backup systems is recorded, the backup identification information;

a data processor for processing a data file; and

a controller for backing up the data file processed by the data processor with the backup system based on a detection result of the detector.

6. A computer unit according to claim 5, further comprising a storage period specifying part for specifying a storage period of the backup data;

wherein the controller saves the data file during the storage period specified by the storage period specifying part.

7. A computer unit according to claim 6, further comprising an accounting part for executing different accounting according to the backup system by the controller.

8. A computer unit according to claim 5, wherein the controller deletes the backed up data file when processing with the data file by the data processor is ended.

9. A recording medium removably loaded to a computer unit, comprising:

a recording medium main body; and

a backup identification information recording area formed on the recording medium main body;

wherein backup identification information indicating one of a plurality of backup systems of the computer unit is recorded in the recording area.

10. A recording medium according to claim 9, further comprising an application recording area which is formed in the recording medium main body and in which a plurality of pieces of application software are recorded;

wherein the backup identification information is recorded for each of the pieces of application software in the backup identification recording area.

11. A recording medium according to claim 9, wherein the recording medium main body includes a recordable area and a reproduction only area, and the backup identification information recording area is formed in the reproduction only area.

12. A recording medium according to claim 9, wherein the backup identification information includes information indicating that backup is not performed and information indicating that backup is performed.

13. A computer system comprising a server and a computer terminal, the server and the computer terminal being connected for communication with each other,

wherein the computer terminal comprises:

a data processor for processing a data file;

a drive unit for driving a removable recording medium in which backup identification information is recorded;

a communication part for communicating with the server; and

a controller for executing an external backup operation to cause the communication part to transmit the data file processed by the data processor as backup data to the server, and changes a system of the external backup operation based on the backup identification information recorded in the removable recording medium; and

wherein the server comprises;

a receiver for receiving the data file as the backup data transmitted from the communication part; and

a storage unit for storing the data file received by the receiver.

14. A computer system according to claim 13, wherein the computer terminal further comprises an accounting part for executing different accounting according to the system of the external backup operation by the controller.

15. A computer system according to claim 14, wherein:

the computer terminal further comprises an input for inputting a user'"'"'s instruction as to the system of the external backup operation; and

the controller executes the external backup operation based on the user'"'"'s instructions with the input.

16. A computer terminal connected to a server for communication, comprising:

a data processor for processing a data file;

a drive unit for driving a removable recording medium in which backup identification information is recorded;

a communication unit for communicating with the server; and

a controller for executing an external backup operation to cause the communication part to transmit the data file processed by the data processor as backup data to the server, and changes a system of the external backup operation based on the backup identification information recorded in the removable recording medium.

17. A computer terminal according to claim 16, further comprising an accounting part for executing different accounting according to the system of the external backup operation by the controller.
