摘要
Provided is a technique capable of efficiently operating files and directories that are stored in storage located in a physically far place from a file server, without causing a network latency. An index creation program is also loaded in a cloud computing environment, and a flag, which indicates whether or not to execute batch processing to a directory that has been migrated to the cloud side, is provided, whereby it becomes possible to collectively execute index creation processing for the migrated directory on the cloud side. More specifically, upon completion of migration of all files under a given directory to the cloud side, a flag, which indicates whether or not to perform batch processing on the cloud side, is validated for the metadata of the directory. Such a batch processing flag can be held for each application such as applications of the index creation processing and the virus check processing.
