摘要： A computer-readable recording medium stores a program that causes a computer to execute a writing control process that includes receiving a writing request to write a first data to a first storage apparatus; determining a second data from among a series of data and based on a writing sequence of the series of data written to the computer and a count of storage areas at a second storage apparatus that sequentially selects from among the storage areas when data is received, a storage area to be over written by the received data, where the second data is written to the first storage apparatus and is identical to data that is stored in the storage area to be selected next at the second storage apparatus; and transmitting copy data of the first data to the second storage apparatus, when the second data has been written to the first storage apparatus.

摘要： An information processing apparatus includes a first storage unit and a processor. The first storage unit includes a first storage area. The processor receives a first request to write first data into the first storage area. The processor requests an external apparatus to write the first data into a second storage area in a second storage unit included in the external apparatus. The processor determines whether a first response has been received from the external apparatus. The first response indicates that the first data has been written into the second storage area. The processor writes the first data into the first storage area when the first response has been received. The processor requests, without writing the first data into the first storage area, the external apparatus to write second data stored in the first storage area into the second storage area when the first response has not been received.

摘要： A storage system having a plurality of storages. The each of the storages include a memory and a processor coupled to the memory. The processor executes a process including transmitting an update request for data which is commonly stored in the plurality of storages according to a predetermined transmission order indicating a path to transfer the update request. The process includes updating data when receiving an update request from another storage. The process includes changing the predetermined transmission order to a transmission order in which one or more storages included in the path are excluded according to the number of times the update request for the data is received.

摘要： A storage device is one of a plurality of storage devices storing replicas of data. The storage device includes a memory and a processor coupled to the memory. The processor executes a process includes transmitting an update request to at least one destination storage device through a plurality of paths when the storage device is requested to update the data by a client. The process includes notifying the client that the updating of the data has been completed when having received a response through one of the paths, the response being issued by the destination storage device serving as the terminal point of the path when the destination storage device receives the update request through all the paths having the destination storage device as the terminal point.
