摘要： 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.

摘要： In a computer system having a computer, a storage system having storage units being coupled to the computer and for storing user data used by the computer, and a backup device being coupled to the computer and the storage system, a backup method is presented for obtaining a backup of the data stored in the storage unit to the backup device. The storage system holds the user data dually in a first and a second storage units. In backing up the user data, a split instruction for releasing the duplex state of the first and the second storage units is sent from the computer to the storage unit. In response to the split instruction, the storage system interrupts the reflection of the update of the user data to the first storage unit onto the second storage unit. Then, a copy instruction for copying the user data held in the second storage unit to the backup device is sent from the computer to the storage system. The storage system operates to transfer the user data inside of the second storage unit to the backup device in response to the copy instruction.

摘要： The present invention makes it possible for a virtual higher-level device disposed on a virtual platform to use prescribed data related to an application. A virtual higher-level device 20 is disposed on a virtual platform 30. A storage system 40 comprises logical volumes 41, 42 for storing prescribed data related to an application program 11. A management computer 50 prepares prescribed logical volumes 43, 44 in the storage system 40 so that the virtual higher-level device 20 is able to use the prescribed data related to the application program, couples a communication interface part of the virtual platform 30 to a communication port part of the storage system 40 so as to make it possible to access the prepared prescribed logical volumes 43, 44 via the virtual platform 30, and further transparently allocates the prescribed logical volumes 43, 44 to the virtual higher-level device 20.
