PROBLEM TO BE SOLVED: To provide a method to split a global file system among multiple servers on an occasion when remote copy is performed. SOLUTION: The local NAS systems replace referrals within the global file system with directories and sends them in place of the referrals to the remote NAS system. Other local NAS systems referred to by the referrals send files and directories under the directories replacing the referrals on the remote NAS system. Alternatively, in order to split copy data of a locally-stored global file system amongst multiple remote NAS systems, the local NAS system replaces specified directories with referrals and sends the referrals with the data to one of the remote NAS systems. The local NAS systems sends files and directories under the directories replaced with referrals to one or more other remote NAS systems as referred to by the referrals. COPYRIGHT: (C)2007,JPO&INPIT
