ABSTRACT:
The amount of work processing (main processing amount) of a database is acquired and accumulated. A value (main processing index) indicating the transition of the amount of main processing amount available in a time frame that is presumed to be required for backup is calculated by using the amounts of main processing accumulated during the latest period of time. The main processing index is compared with the backup executability reference value which is a threshold value determining the backup executability. If the main processing index is smaller than the threshold value, backup is executed. If the main processing index is larger than the threshold value, backup is not executed but the amount of main processing is again acquired to calculate the main processing index, and the main processing index is compared with the backup executability reference value.
