INFORMATION PROCESSING SYSTEM AND DATA UPDATE CONTROL METHOD

摘要

An arithmetic operation unit receives a request to update a first data group during restoration using first history information and generates second history information indicating a history of updates. The arithmetic operation unit predicts a time taken until completion of restoration using the second history information on the basis of an amount of the second history information. The arithmetic operation unit compares the predicted time with a threshold and limits at least part of updates of the first data group during the restoration using the second history information on the basis of the comparison result.

1. A non-transitory computer-readable storage medium storing therein an update control program that causes a computer to perform a process, the computer being in a system which includes a first storage device and a second storage device, the process comprising:
receiving a request to update a first data group stored in the first storage device during restoration of a second data group stored in the second storage device using first history information indicating a history of updates of the first data group; generating second history information indicating a history of updates based on the received request; predicting a time taken until completion of restoration using the second history information based on an amount of the second history information; and limiting, based on the predicted time, at least part of updates of the first data group during the restoration using the second history information.
