PROBLEM TO BE SOLVED: To arrange files in a manner so that a storage system can provide appropriate performance, reliability and other properties for each file. SOLUTION: A method and system are provided in which files copied from a local storage system 10008 to a remote storage system 10108 are copied in such a manner that they reflect the arrangement and hierarchy of those files in the local storage system 10008, including storage class. This allows the remote storage system to provide the desired properties and performance for the files in the same manner as the local storage system. Further, in the case where a file in the local storage system is migrated from one storage class to another storage class, the local storage system sends a migration command to the remote storage system. The migration command includes the target storage class to which the corresponding file in the remote storage system is to be migrated. COPYRIGHT: (C)2008,JPO&INPIT |
