Abstract

A non-transitory computer-readable recording medium storing therein a backup control program that causes a computer to execute a process comprising: detecting storage access load and processor load of a target computer, the storage access load being a load of access to a storage of the target computer, and the processor load being a load on a target processor of the target computer; determining a data volume of backup processing based on the storage access load and the processor load, the backup processing accompanying access to the storage and operation of the target processor; and performing the backup processing based on the data volume.

First claim

What is claimed is:

1 . A non-transitory computer-readable recording medium storing therein a backup control program that causes a computer to execute a process comprising:
detecting storage access load and processor load of a target computer, the storage access load being a load of access to a storage of the target computer, and the processor load being a load on a target processor of the target computer; determining a data volume of backup processing based on the storage access load and the processor load, the backup processing accompanying access to the storage and operation of the target processor; and performing the backup processing based on the data volume.

2 . The recording medium according to claim 1 , wherein
the determining determines the data volume of backup processing based on spare capacity of the storage and an idle ratio of the target processor, the spare capacity of the storage being calculated from the storage access load, and the idle ratio of the target processor being calculated from the target processor load.

3 . The recording medium of claim 1 , wherein
the detecting detects the storage access load of the target computer by recording a number of times that access to the storage occurred within a unit time period, and a time taken for each individual access, and by detecting a total value of the time taken for the individual accesses to the storage that occurred within the unit time period as the load of access to the storage of the target computer within the unit time period.

4 . The recording medium of claim 2 , wherein:
the detecting detects the storage access load of the target computer by recording a number of times access to the storage occurred within a unit time period, and a time taken for each individual access, and by detecting a total value of the time taken for the individual accesses to the storage that occurred within the unit time period as the load of access to the storage of the target computer within the unit time period; and the spare capacity of the storage is calculated as an availability time that is the total value of the time taken for the individual accesses to the storage that occurred within the unit time period subtracted from the unit time period.

5 . The recording medium of claim 4 , wherein:
the data volume of the backup processing corresponding to the spare capacity of the storage is calculated by multiplying the availability time calculated as the spare capacity of the storage, by the data volume accessible per unit time period expressed in access performance information that is stored in a first storage section and that indicates a data volume accessible per unit time period with respect to the storage.

6 . The recording medium of claim 1 , wherein:
the detecting further comprises recording a number of times, and a particular time, that the target processor is occupied within a unit time period, in a second storage section, and the detecting detects the processor load based on a total value of time that the target processor is occupied within the unit time period.

7 . The recording medium of claim 1 , wherein:
the detecting the storage access load and the processor load of the target computer includes processing to update a database stored on first storage; and the backup processing includes processing that stores incremental updates to the database on second storage.

8 . An information processing device comprising:
a memory; and a processor configured to execute a procedure, the procedure including:
detecting storage access load and processor load of a target computer, the storage access load being a load of access to a storage of the target computer, and the processor load being a load on a target processor of the target computer;
determining a data volume of backup processing based on the storage access load and the processor load, the backup processing accompanying access to the storage and operation of the target processor; and
performing the backup processing based on the data volume.

9 . The information processing device of claim 8 , wherein
the determining determines the data volume of backup processing based on spare capacity of the storage and an idle ratio of the target processor, the spare capacity of the storage being calculated from the storage access load, and the idle ratio of the target processor being calculated from the target processor load.

10 . The information processing device of claim 8 , wherein
the detecting detects the storage access load of the target computer by recording a number of times that access to the storage occurred within a unit time period, and a time taken for each individual access, and by detecting a total value of the time taken for the individual accesses to the storage that occurred within the unit time period as the load of access to the storage of the target computer within the unit time period.

11 . The information processing device of claim 8 , wherein the detecting further comprises:
recording a number of times, and a particular time, that the target processor is occupied within a unit time period, and detecting the processor load based on a total value of time that the target processor is occupied within the unit time period accompanying execution of the processing.

12 . The information processing device of claim 8 , wherein:
the detecting the storage access load and the processor load of the target computer includes processing to update a database stored on first storage; and the backup processing includes processing that stores incremental updates to the database on second storage.

13 . An information processing method comprising:
by a processor:
detecting storage access load and processor load of a target computer, the storage access load being a load of access to a storage of the target computer, and the processor load being a load on a target processor of the target computer;
determining a data volume of backup processing based on the storage access load and the processor load, the backup processing accompanying access to the storage and operation of the target processor; and
performing the backup processing based on the data volume.

14 . The information processing method of claim 13 , wherein
the determining determines the data volume of backup processing based on spare capacity of the storage and an idle ratio of the target processor, the spare capacity of the storage being calculated from the storage access load, and the idle ratio of the target processor being calculated from the target processor load.

15 . The information processing method of claim 13 , wherein
the detecting detects the storage access load of the target computer by recording a number of times that access to the storage occurred within a unit time period, and a time taken for each individual access, and by detecting a total value of the time taken for the individual accesses to the storage that occurred within the unit time period as the load of access to the storage of the target computer within the unit time period.

16 . The information processing method of claim 13 , wherein the detecting further comprises:
