1. A storage system comprising:
a data buffer configured to receive input of data to be stored of a predetermined volume and store the data temporarily; a dividing unit configured to generate divided data by dividing the data inputted into the data buffer; and a storage processing unit configured to store the divided data obtained by division by the dividing unit into a storage device and, when storing other divided data of a content identical to that of the divided data already stored in the storage device into the storage device, eliminate duplicate storage by reference of the divided data already stored in the storage device as the other divided data, wherein the dividing unit is configured to, at preset timing, generate the divided data by dividing the data inputted into the data buffer by a preset division standard based on a content of the data, and also divide, by the division standard, connected data that residual data and continuing data are connected in the data buffer, the residual data being left without being divided by the division standard, and the continuing data continuing to the residual data and being inputted in the data buffer, wherein the dividing unit is configured to, at timing of reception of input of a present writing command, divide the data inputted into the data buffer by the division standard to thereby generate the divided data divided by the division standard and the residual data left without being divided by the division standard, and also divide, by the division standard, the connected data that the continuing data inputted into the data buffer after generation of the above data and the residual data are connected in the data buffer, wherein the storage processing unit is configured to, at timing of reception of input of the writing command, execute a process of storing the divided and the residual data both generated by the dividing unit into the storage device, and wherein the dividing unit is configured to input the residual data stored in the storage device into the data buffer and divide, by the division standard, the connected data that the residual data and the continuing data both inputted in the data buffer are connected in the data buffer. |
