Abstract

PURPOSE:To improve operability by providing a suspending means for interrupting temporarily a program which is being executed, etc., so that a file can be saved in a file backup device without waiting for the end of the program which is being executed. CONSTITUTION:A program management table registering means 2 registers management information of a program which receives a program starting request in a program management table. Subsequently, in the case the program brought to starting request is a file backup program, a program checking means 3 checks the program management table by an execution checking means 5. As a result, if other program which is being executed exists, its program is set to an interrupted state temporarily by a suspending means 6, and the starting request of the file backup program is given to a file backup program executing means 8. The means 8 reads out a file on a magnetic disk device 7, and allows a file backup device 9 to write it. In such a way, the file can be saved without waiting for the end of the program which is being executed, and the operability can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a file saving method, particularly to a file saving method in an information processing system connected to a streaming file backup device.

[Conventional technology]

Conventionally, in this type of file saving method, when saving the contents of a magnetic disk file, for example, when another program is running, the magnetic disk file may be used by this program, and the saved data is saved during that time. In order to prevent the saved data from being disturbed by the streaming operation of the file backup device due to the interruption of reading, file saving is not performed.

[Problem to be solved by the invention]

The conventional file saving method described above has the disadvantage that file saving cannot be performed while other programs are running, and that a file saving program can only be started after the other programs have finished.

[Means to solve the problem]

The file saving method of the present invention, in an information processing system connected to a streaming file backup device, includes a program management table registration means for registering management information of a program that has received a startup request in a program management table; When the program is a file backup program, check whether there are other programs being executed from the program management table;
There is an execution check means that performs temporary suspension processing on the running program and then starts the file backup program, and checks the program management table after the execution of the file backup program ends and checks if there is a temporarily suspended program. and an interruption check means for canceling the temporary interruption of the operation.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, in which program startup request receiving means 1. Program management table registration means 2.
Program check means 3. Program execution means 4. Execution check means 5. Suspend means 6. Magnetic disk device7. File backup program execution means 8. File backup device9. Suspend check method 1
0 and a suspension release means 11. Program management table registration means 2. Program check means 3. Execution check means 5. Suspend means 6
．． Suspend check means 10 and suspend release means 11 are functional blocks added to the conventional file saving method for the purpose of the present invention.

In the above configuration, the program activation request receiving means 1 receives a program activation request, and the program management table registration means 2 registers the management information of the program for which the activation request has been received in the program management table. The program checking means 3 checks whether the program requested to be started is a file backup program.
If the program requested to be activated is not a file backup program, it is executed by the program execution means 4. If the program requested to be activated is a file backup program, the execution check means 5 checks the program management table and if there is no other program being executed, a request to activate the file backup program is given to the file backup program execution means 8.

If there are other programs being executed, the suspend means 6 temporarily suspends the other programs, and then a request to start the file backup program is given to the file backup program execution means 8. The file backup program execution means 8 reads the file on the magnetic disk device 7 and causes the streaming type file backup device 9 to write the file.

When the file backup program finishes running,
The suspend check means 10 checks whether there is any program on the program management table that is temporarily suspended by the suspend means 6. If there is a program in a temporarily suspended state, the suspended state is released by the suspend release means 11, and the execution of the suspended program is continued.

〔Effect of the invention〕

As explained above, the present invention provides a suspend means for temporarily suspending a running program, thereby saving files in a magnetic disk device to a streaming file backup device without waiting for the running program to finish. This has the effect of improving operability.

Brief description of the drawing FIG. 1 is a block diagram of an embodiment of the present invention.

Claims (1)

[Claims] In an information processing system connected to a streaming file backup device, a program management table registration means for registering management information of a program that has received a startup request in a program management table; and when the program that has received a startup request is a file backup program. includes an execution check means for checking the presence or absence of other programs being executed from the program management table, temporarily suspending the running programs, and then starting the file backup program; and terminating the execution of the file backup program. A file saving method characterized by comprising an interruption check means for later checking the program management table and, if there is a temporarily interrupted program, canceling the temporary interruption of the program.
