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.

主权项

1. A non-transitory, computer-readable recording medium having stored therein a program for causing a computer to execute a writing control process comprising:
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 (1) a writing sequence of the series of data written to the computer before the writing request is received and (2) 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, wherein the second data is to be 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 determined second data has been written to the first storage apparatus.
