摘要： A buffer memory capable of storing contents of a plurality of tracks of a disk volume is provided in a disk controller or a disk drive, and in dump processing requested by a higher rank unit (CPU) to the disk controller, the data is immediately transferred from the buffer memory if the data to be dumped is present in the buffer memory, and if the data to be dumped is not present in the buffer memory, dump prefetching into the buffer memory is started and the execution of the dump processing is interrupted so that an on-line input/output operation other than the dump processing is accepted. When the dump prefetching into the buffer memory is over, the interrupted dump processing is resumed.

摘要： In a data processing system having a first external memory, a second external memory, and a control memory for storing information on data renewals in the first external memory, a system and a method provide for back-up operations in parallel with ordinary data processing, including dump processing in which renewed data parts in the first external memory are copied as backup data into the second external memory with reference to the contents of the control memory. The method provides the step of storing into the control memory first identifier information for identifying areas of the first external memory where data items were renewed; the step of storing into the control memory second identifier information for identifying areas of the first external memory where data items were renewed during the dump processing; and the step of erasing at completion of the dump processing the first identifier information items except those which identify the same areas as identified by the second identifier information items. Thus, ordinary job processing and the renewals of the data items of the first external memory can be performed even in the course of the data dumping processing.

摘要： Two data centers located in the vicinity are connected using a synchronous transfer copy function, and one of the data centers is coupled with a third data center disposed at a remote location by an asynchronous remote copying function. The order whereat a storage sub-system located in the vicinity has received data from a host is consistently guaranteed, and the third data center holds the data. Further, each storage sub-system includes a function whereby, during normal operation, data can be exchanged and the data update state can be obtained by the storage sub-systems located in the two data centers that do not directly engage in data transmission.

摘要： An information processing system has a processor, a first storage unit, a controller connected between said processor and said first storage unit, and a second storage unit connected to said processor and for storing dump data, and a dump method thereof are disclosed. The controller manages updated regions of the first storage unit as write regions. In response to a dump request issued by the processor, the controller manages regions which are managed as the write regions and included in a dump portion as protected regions. If a write request for a region which is managed as protected region, the controller saves contents of the region to dump point file before executing a write operation, and release the region from the protected regions. The controller transfers contents of regions managed as protected track and contents of the dump point file to the processor as contents of regions to be dumped. At the end of dump processing, the controller deletes the dump point file and terminates management of the protected regions.
