Abstract

PROBLEM TO BE SOLVED: To produce a duplicate of a computer file without giving any load to other jobs which are carried out in parallel to the file duplicating job by inquiring automatically about the new producing/updating state of the computer file in a short time and at a fixed interval. SOLUTION: An automatic duplicating device 1 inquires of a storage A 3 about the new producing/updating information on a computer file or receives this information via an API 2 and produces the duplication of a new producing/ updating file of the storage A 3 for a storage B 4. At the same time, the device 1 monitors the motion of a CUP 5 and produces a duplicate of the computer file when the load factor of the CPU 5 lowers continuously for a fixed time, discontinues temporarily the production of the file duplicate when the load factor of the CPU 5 rises and then restarts the production of the file duplicate when the load factor of the CPU 5 lowers continuously again for a fixed time. As a result, a user can produce a computer file with no special endeavor required and can duplicate the computer file without giving any load to the CPU 5.

BACKGROUND OF THE INVENTION Computer files are very unstable and fragile. Therefore, it is necessary to make a copy in the same device or an external device in case the computer file is damaged. Conventionally, when creating a copy, it is common to manually make the copy or to automatically create the copy at a designated time. However, duplication of this data file imposes a load on the central operator (CPU), so that performing other operations at the same time has a disadvantage that other operations are inefficient.

The method of manually making a copy of a computer file is cumbersome and difficult to perform on a regular basis. Further, in the method of automatically creating a copy at a designated time, it is difficult to always copy the latest file because the updated time interval becomes large. For this reason, in the conventional method, since the duplicate of the computer file created is not the latest, it is often useless after all. In addition, the computer was heavily loaded during duplication, and other duties were less efficient during duplication.

Means for Solving the Problems In order to solve the above-mentioned object, the present invention automatically inquires whether a computer file has been newly created / updated at a short fixed interval, and newly created / updated. Automatically create duplicate computer files. Also, a common information interface API (Application Program I) for exchanging information with the present invention to an external device.
By attaching information indicating that data has been newly created / updated from another device and automatically creating a copy, the time lag of the copy creation is minimized, and at regular intervals. Since the update information is not checked, the latest program file can be copied reasonably. Furthermore, for a certain period of time (usually 5-60
Second) After confirming that the central operator (CPU) is not used continuously or hardly used, the copying is started, and when the load factor of the CPU increases, the temporary copying is stopped. According to this method, the latest computer file copy is always created automatically on the internal or external storage medium, so the user can create a valuable copy of the latest computer file without any special effort. So that you can be prepared for it in a perfect system. Further, according to the present invention, since a copy can be created without applying a load on the CPU, the load on other work in parallel progress is small.

A copy of the newly created / updated file of the storage device A is created in the storage device B. At this time, the present invention monitors the movement of the CPU (central operator) and continuously executes the CPU for a certain period of time.
When the load factor of the CPU becomes low, a copy is created,
If the load factor of the CPU rises, the creation of the copy is suspended, and further, if the load factor of the CPU decreases continuously for a certain period of time, the creation of the copy is restarted.
