ABSTRACT:
A storage system that realizes data duplication between a master storage and a remote storage by performing a remote data transfer is provided. The storage system monitors the amount of write data from a host apparatus to the master storage. If as a result of monitoring, the amount of write data is found to exceed a predetermined value, the data transfer to the remote storage is automatically halted and a differential management of updated data takes place within the master storage using a differential bitmap.
