Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for performing data maintenance such as relocation of recorded data and error checking, a method therefor, and a device incorporating the configuration, and particularly, the timing for performing data maintenance is heavy. This is so that the decision can be made without burden.

2. Description of the Related Art Conventionally, in personal computers and the like,
When writing data to a storage area, when the data does not fit in a continuous area of the storage area, a process called fragmentation is performed in which the data is scattered and written in various areas. The data recorded by being dispersed in a plurality of areas as described above requires a process for collecting the respective data when the data is read, and the access speed becomes slow. Therefore, the user activates the maintenance program built into the personal computer as needed to align the data and correct the data discontinuity. In addition, even when the data accumulated in the storage area is destroyed or lost, the user activates the maintenance program to check the data destruction status or repair the data.

As a method of automating such maintenance processing, there is known a method of automatically activating a maintenance program on a specific day of the week or a date and time by a scheduler program. However, this method has a problem that the data maintenance process is not performed when the power of the device is not turned on at the designated date and time.

On the other hand, Japanese Unexamined Patent Publication No. 8-106411 discloses a method of identifying the operating state of the apparatus and automatically performing the data maintenance process when the apparatus is not operating. In this method, the processing of monitoring the operating rate of the device and the general processing of the operating system are alternately repeated, and in the operating rate monitoring processing, the operating rates of the CPU and the data storage device are calculated every one second.

As for the operating rate of the CPU, it is repeatedly checked whether or not the CPU is in an idle state waiting for a command or interrupt, the number of checks and the number of idle states are counted, and the number of idle states is calculated every second. By dividing by the number of checks, the operating rate of the CPU per second is calculated. In addition, the operating rate of the storage device is checked by repeatedly checking whether or not the storage device is being accessed. The number of checks and the number of times of access when the storage device is being accessed are counted. Is divided by the number of checks to calculate the operation rate of the storage device per second. And
When the operating rates of the CPU and the storage device are lower than the threshold value continuously for a predetermined time or longer, the maintenance program is activated and the data maintenance work is started.

[0006]

However, in the conventional method in which the timing of the data maintenance process is determined from the operating rate, the performance (performance, efficiency) of the apparatus is significantly reduced during the operating rate monitoring processing, and it is necessary to operate the apparatus. When the above occurs, there is a problem that the processing ability is deteriorated and the response becomes slow, which gives the user an unpleasant feeling.

The present invention solves these conventional problems, and provides a data maintenance apparatus which can determine the timing of data maintenance processing based on the operating state without a heavy processing load. , A device incorporating the same, a data maintenance method thereof, and a computer program for executing the method.
