The operating system file 21 stores the operating system and various application software necessary for normal operation of the computer 2 in a file form. When these are executed by the computer 2, the operating unit 211 Function as The operation unit 211 executes those functions when the computer 2 executes the OS stored in the operation system file 21 and general application software such as a word processor and a spreadsheet.

The master log file 22 holds the operation history of the computer 2 and is referred to at the time of self-maintenance. The backup file 23 stores backup data of frequently-recovered data among data (folders / files) to be repaired during the self-maintenance of the computer 2 itself, in other words, backup data that is frequently used. .

In the self-maintenance system file 24, various software necessary for self-maintenance of the computer 2 itself are filed and stored.
When they are executed by the computer 2, they function as a diagnosis restoration unit 212, a diagnosis restoration result log collection / aggregation unit 213, an additional condition setting unit 214, a diagnosis restoration result log analysis unit 215, and a backup medium change unit 216.

The diagnostic repair area setting file 25 stores information for specifying data (folders / files) in the backup file 23 which is determined to require diagnostic repair when executing self-maintenance.

The diagnostic result log file 26 contains the diagnostic restoring unit 21
2 When the self-diagnosis is performed, the result is stored. In the repair log file 27, information for identifying data determined to require repair in accordance with the contents of the diagnosis result log file 26 is recorded. When the repair is performed according to the contents of the repair log file 27, the result is recorded in the diagnostic repair result log file. The diagnostic repair result log file 28 is created each time self-maintenance is performed.

Each time self-maintenance is performed, information (file name, folder name) specifying the repaired data and the number of times of repair are stored in the diagnostic repair result log totaling file 29. Specifically, the contents of the diagnostic repair result log file 28 created each time self-maintenance is executed are accumulated in the diagnostic repair result log totaling file 29.

In the analysis condition file 30, the storage destination of each data is the backup file 23 or an auxiliary storage medium.
An analysis condition for determining whether to set to 40, for example, a repair frequency, a repair frequency, and the like are set and stored. The analysis result file 31 stores information for specifying data whose backup area has been newly changed from the backup file 23 to the auxiliary storage medium 40.

In the backup area setting file 32, with respect to each data in which the information for specifying each as the diagnosis and restoration target is stored in the diagnosis and restoration area setting file 25,
Each backup data is a backup file
Information indicating which is stored in the storage medium 23 or the auxiliary storage medium 40 is stored.

Next, the internal functions of the computer 2 other than the operation unit 211 will be described. The diagnostic restoring unit 212 executes the self-diagnosis of the computer 2 itself at an appropriate timing, for example, when the power is turned on or when an instruction is given from the user, determines whether there is data to be restored based on the backup data, and restores the data. If there is data to be stored, the backup area of the backup data, specifically, the backup file 23 or the auxiliary storage medium
The restoration is performed by judging from the storage content of the backup area setting file 32 whether the value is 40 or not, and reading and rewriting necessary backup data.

The diagnostic restoration result log collection / aggregation unit 213 adds the contents of the newly created diagnostic restoration result log file 28 to the recorded contents of the diagnostic restoration result log aggregation file 29 every time the self-maintenance is executed.

The additional condition setting unit 214 is prepared for the user to set the analysis condition by the diagnosis and restoration result log analysis unit 215, and the setting condition is stored in the analysis condition file 30.

When a predetermined condition is satisfied, for example, when self-maintenance has been performed a predetermined number of times, or when a predetermined time has elapsed, the diagnosis restoration result log analysis unit 215
The recorded contents of the diagnostic restoration result log totaling file 29 are analyzed in accordance with the contents of the analysis condition file 30, and it is determined whether or not there is backup data whose backup area needs to be changed from the backup file 23 to the auxiliary storage medium 40. Then, when there is data whose backup area should be changed from the backup file 23 to the auxiliary storage medium 40, the diagnosis and restoration result log analyzer 215 stores information specifying the data in the analysis result file 31.

The backup medium changing unit 216 stores the corresponding data in the backup file 23 in accordance with the recorded contents of the analysis result file 31, that is, information specifying data to be newly changed from the backup file 23 to the auxiliary storage medium 40 in the backup area. Then, the backup data is compressed and stored in the auxiliary storage medium 40, and the content of the backup area setting file 32, that is, the backup area setting of the backup data is rewritten.

FIG. 2 is a flowchart showing a self-maintenance processing procedure of the computer according to the present invention. Hereinafter, the self-maintenance processing of the computer 2 will be described with reference to the flowchart of FIG.

When the computer 2 is powered on and started up, the diagnostic restoring unit 212 is started up by software for self-diagnosis stored in the self-maintenance system file 24 of the computer 2. Then, a self-diagnosis of the computer 2 is first performed by the diagnostic restoring unit 212 (step S11). However, in the present embodiment, the same self-maintenance can be performed not only at the time of turning on the power but also at any time as long as the maintenance process is possible, by giving an instruction from the user at any time.

When the self-diagnosis is performed by the diagnosis and restoration unit 212, the contents of the operation system file 21 and the master log file 22 are compared, and the system environment of the computer 2, that is, the folder / file of the software or the like is changed or new. It is diagnosed whether or not the file has been created, and a diagnosis result log file 26 is created (step S12). Then, based on the content of the newly created diagnostic result log file 26 and the storage content of the diagnostic repair area setting file 25, that is, data that needs to be actually repaired based on information for specifying data targeted for diagnostic repair. Is created (step S13).

According to the contents of the newly created repair log file 27, the diagnostic repair section 212 stores backup data of data (folder / file) requiring repair in the backup file 23 or in the auxiliary storage medium 40. The information indicating whether the data is stored is read from the backup area setting file 32. Then, the diagnostic restoration unit 212
Reads the backup data from the backup file 23 if the backup data of the data requiring restoration is stored in the backup file 23, and reads the backup data from the auxiliary storage medium 40 if the backup data is stored in the auxiliary storage medium 40. After reading and decompressing, the part that needs to be repaired is repaired by reinstalling it in the operation system file 21 (step S14).
After this, a diagnostic repair result log file that records the repair results
28 are created (step S15). The diagnostic repair result log file 28 is newly created each time the self-maintenance function is executed.

FIG. 3 is a schematic diagram showing the contents of the backup area setting file 32. As shown in the schematic diagram of FIG. 3, the backup area setting file 32 stores "1" when the backup area is the backup file 23 for each of the folders A, B, C,. In the case of the medium 40, “0” is stored.

FIG. 4 is a schematic diagram showing the contents of the diagnosis result log file 26. As shown in the schematic diagram of FIG. 4, each file A1, A2... Of folder A and each file B of folder B
If it is determined that restoration is necessary for 1, B2 ... ”
It is assumed that “1” is stored and “0” is stored when it is diagnosed as unnecessary.
From the storage contents of 26 and the storage contents of the diagnostic repair area setting file 25, information for specifying data that actually needs to be repaired is stored in the repair log file 27.

In this way, the diagnostic restoration result log file
When 28 is created, its contents are
The diagnostic / repair result log total file 29 is updated by adding the result to the current contents of the diagnostic / repair result log total file 29 by the total unit 213 in the unit of drive, folder, file, etc. S16).
Then, the diagnostic restoration result log analyzer 215 resets the backup area based on the contents of the diagnostic restoration result log total file 29 and the analysis condition file 30 (step S1).
8). Specifically, an auxiliary storage medium is stored in any of the backup data stored in the backup file 23.
It is determined whether there is backup data to be stored in 40.

FIG. 5 is a schematic diagram showing the contents of the diagnostic restoration result log totaling file 29. In this example, the number of restorations, the frequency of restoration, and the like are recorded for each of the files A1, A2,... Of the folder A and each of the files B1, B2,.

However, the processing by the diagnosis and restoration result log analysis unit 215 is executed once each time the self-diagnosis by the diagnosis and restoration unit 212 is executed a predetermined number of times (step S17). In the processing by the diagnosis and restoration result log analysis unit 215, the user makes settings through the additional condition setting unit 214, thereby changing the setting contents of the analysis condition file 30, and thereby, a backup area reflecting the user's will. Can be reset.

Hereinafter, the above-described process of resetting the backup area by the diagnosis / recovery result log analyzer 215 will be described with reference to the flowchart of FIG. 6 showing the details of the processing in step S18.

First, if all folders / files under a specific folder have not been restored each time the self-diagnosis is executed (“YES” in step S181), the specific folder is backed up in the auxiliary storage medium 40. Is set (step S185). Such a folder does not usually need to be repaired when executing the self-diagnosis, so that backup in the auxiliary storage medium 40 is sufficient.

Second, if the specific file under the specific folder is not repaired each time the self-diagnosis is executed ("NO" in step S182), the specific file is backed up in the auxiliary storage medium 40. Is set to (step S185). In this case, specific examples include an OS system file (for example, a device driver) and an application execution file. These files are only read temporarily with the operation of the computer 2 and therefore do not need to be restored each time the self-diagnosis is executed. Therefore, backup on the auxiliary storage medium 40 is sufficient.

Third, when some files under the specific folder are repaired each time self-diagnosis is executed, but most other files are not repaired (step S183
"YES"), the specific folder is a backup file
It is backed up at 23 (step S186). The fact that some files under a specific folder are repaired each time the self-diagnosis is executed means that they need to be repaired even when the normal self-diagnosis is executed. It is desirable to keep.

Fourth, if most files under a specific folder are not repaired, but some files are sometimes repaired ("YES" in step S184), the particular folder is basically It is backed up by the backup file 23, but the final decision is left to the user.

If none of the above-mentioned steps S181, S182, S183, S184 applies (“N” in step S184)
O "), the folder is backed up by the backup file 23 (step S186).

As described above, the diagnosis and restoration result log analysis unit
If the backup area is reset by the backup file 215 and the backup area setting is changed from the backup file 23 to the auxiliary storage medium 40,
(“YES” in S19), the information specifying the data is stored in the analysis result file 31 (step S20), and the backup medium changing unit 216 according to the contents,
The backup area is changed by compressing the corresponding backup data stored in 23 and storing it in the auxiliary storage medium 40 (step S21). Finally, the contents of the backup area setting file 32 are used to set the above-mentioned backup area. Updated according to the change (step S22).

As a result, the backup area setting file 32 stores the backup area of the backup data of the data that needs to be repaired at the next execution of the self-diagnosis. According to the storage content of the area setting file 32, the backup data of the data that needs to be restored is read from the backup file 23 or read from the auxiliary storage medium 40 and decompressed before being restored.

For example, when the folder B stored in the diagnostic and restoration result log total file 29 shown in the schematic diagram of FIG. 5 corresponds to the second case described above, it is shown in the schematic diagram of FIG. "1" corresponding to the folder B of the contents of the backup area setting file 32 is rewritten to "0", and the backup area is changed from the backup file 23 to the auxiliary storage medium 40. After this, computer 2
Becomes the actual operation state (step S23). If the number of executions of the self-maintenance has not reached the predetermined number in step S17, the computer 2 enters the operating state at that time.

In the above-described embodiment, the present invention is applied to a stand-alone computer. However, when the above-described processing is performed by itself, the computer may be connected to a network. Needless to say.

In the above embodiment, the present invention is applied to a stand-alone computer.
