Further, after the above processing is completed, history information such as extraction destination type and extraction status is recorded (S109).

  On the other hand, when it is determined that today is the date of automatic extraction to DVD, the plant data management server 2 is requested to send the test data for today (S110). In response to this request, the plant data management server 2 extracts the corresponding test data from the data storage unit 2b and transmits it to the test data backup server 4 (S111), and the test data backup server 4 transmits the transmitted test. Data is stored only in the DVD4c disk (S112).

  Thereafter, similarly to the above process, it is determined whether or not the extraction process by backup described above has failed (S113). If the extraction process fails, a notification to that effect is set to the system administrator and the extraction date. It is automatically distributed to the e-mail address of the setter (S114). Further, after the above processing is completed, history information such as the extraction destination type and extraction status is recorded (S115).

  Therefore, the test data stored in the plant data management server 2 is deleted when a predetermined period elapses, but the user sets the extraction date in advance, so that the test data on the scheduled extraction date is at least a DVD. Thus, it is possible to use the test data of the set extraction date even after a predetermined period has elapsed. In addition, by adopting such a backup technique, it is not necessary to greatly change the capacities of the data storage units 2b and 4b of the plant data management server 2 and the test data backup server 4.

  Further, the test data of the extraction date can be stored only in the DVD 4c or stored in the DVD 4c and the data storage unit 4b of the test data backup server 4 according to the user setting. It is possible to select a storage medium as appropriate according to the usage mode, and it is possible to provide a wide range of usage methods. In addition to the automatic extraction function, a manual backup function is provided, so if the automatic extraction function does not work or if you have forgotten to set it, you can test it within the data storage period of the plant data management server 2 Data can be backed up.

  In the above-described configuration, an example in which the control terminal 3 is used as an input unit when performing various settings necessary for the backup processing is shown. However, the input device 4e of the test data backup server 4 is used. The same processing may be performed. In the above description, the backup technology example for collecting and storing the coal combustion test data has been described. However, it may be used for collecting and storing another huge amount of test data. Furthermore, in the above-described configuration, an example is shown in which a DVD is used as the auxiliary storage device 4c having a removable storage medium. However, another device having a removable storage medium may be used instead.
