  • Information processing system and method of controlling the same
    Patent number: 8688632
    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).
