Abstract

Proposed are a backup apparatus and a backup method capable of improving the backup performance, as well as a file reading apparatus capable of improving the file reading performance. As a result of determining a read sequence upon reading the respective files from a disk device based on a physical address of the respective storage areas storing data of each of the files in the disk device, and sequentially reading data of each of the files from the disk device according to the determined read sequence, overhead such as the head seek and rotational delay in the disk device upon reading a plurality of files from such disk device can be dramatically reduced.
