Abstract: In an information processing system 1 including first to third storage systems 50a to 50c, the first storage system 50a performs stubbing by managing entity data of a file in the second storage apparatus 10b, migration by replicating the data of the file to the second storage apparatus 10b, and recall by writing the entity data of the file from the second storage apparatus 10b back to the first storage apparatus 10a. Moreover, the second storage system 50b performs remote copy by replicating metadata of the migrated file from the first storage apparatus 10a to the third storage apparatus 10c at timing of the migration (synchronously), and replicating the entity data of the file to the third storage apparatus 10c at timing independent of the timing of the migration (asynchronously).

Abstract translation: 在包括第一至第三存储系统50a至50c的信息处理系统1中，第一存储系统50a通过管理第二存储装置10b中的文件的实体数据来执行存根，通过将文件的数据复制到第二存储装置 10b，并且通过将文件的实体数据从第二存储装置10b写回到第一存储装置10a来进行调用。 此外，第二存储系统50b通过在迁移（同步）的定时将从第一存储装置10a到第三存储装置10c的迁移文件的元数据复制进行远程复制，并将文件的实体数据复制到第三存储 装置10c，其时间与移动的定时无关（异步地）。
