Abstract
The purpose of the present invention is, in a file storage, to shorten an access response time to shared data. When a file storage apparatus receives a command for a specific manipulation of a file system, a specific apparatus determines, based on a state of the file system and a manipulation history, whether or not an unapplied manipulation affects a target of the specific manipulation, the unapplied manipulation being a manipulation which has been previously executed by another file storage apparatus among a plurality of file storage apparatuses and which has not been applied to the file system. When it is determined that the unapplied manipulation affects the target of the specific manipulation, the file storage apparatus applies the unapplied manipulation to the file system, executes the specific manipulation on the file system, and transmits, to a cloud storage apparatus, manipulation information which represents the specific manipulation.
