Abstract
An acquisition unit of an information processing apparatus acquires access information indicating the state of access to a volume of a disk device at least for data read. A determination unit detects a volume in which a sequential read was performed, on the basis of the acquired access information, and determines the volume as a backup source for a backup.
Claims13
An information processing apparatus comprising a processor configured to perform a procedure including:
- acquiring access information indicating a state of access to a volume of a disk device at least for data read;
- acquiring an operation instruction made to a tape device regarding a backup of data to a magnetic tape of the tape device;
- detecting a volume in which a sequential read is being performed, on the basis of the acquired access information at a time of acquisition of the operation instruction, the detected volume being a storage area in the disk device;
- determining the detected volume as a backup source volume in the disk device for the backup of the data to the magnetic tape specified in the operation instruction, the backup being currently performed;
- and
- causing the tape device to delay responding to another operation instruction acquired during the backup being currently performed for a predetermined delay time after completion of an operation in accordance with said another operation instruction.

A tape device comprising:
- a tape drive that is capable of reading and writing data to a magnetic tape of the tape drive;
- and
- a controller configured to perform a procedure including:
- acquiring access information from a disk device, the access information indicating a state of access to a volume of the disk device at least for data read;
- monitoring inputs of operation instructions to the tape device regarding a backup of data to the magnetic tape of the tape drive;
- detecting a volume in which a sequential read is being performed, on the basis of the acquired access information at a time of an input of an operation instruction to the tape device;
- determining the detected volume as a backup source volume in the disk device for the backup of the data to the magnetic tape specified in the operation instruction, the detected volume being a storage area in the disk device, the backup being currently performed;
- operating the tape device in accordance with an operation instruction acquired during the backup being currently performed;
- and
- responding to the acquired operation instruction after a predetermined delay time elapses from completion of the operating.

A non-transitory computer-readable recording medium storing a program causing a computer to perform a procedure comprising:
- acquiring access information indicating a state of access to a volume of a disk device at least for data read;
- acquiring an operation instruction made to a tape device regarding a backup of data to a magnetic tape of the tape device;
- detecting a volume in which a sequential read is being performed, on the basis of the acquired access information at a time of acquisition of the operation instruction, the detected volume being a storage area in the disk device;
- determining the detected volume as a backup source volume in the disk device for the backup of the data to the magnetic tape specified in the operation instruction, the backup being currently performed;
- and
- causing the tape device to delay responding to another operation instruction acquired during the backup being currently performed for a predetermined delay time after completion of an operation in accordance with said another operation instruction.
