INFORMATION PROCESSING APPARATUS AND DUPLICATION METHOD

摘要

An information processing apparatus duplicates the state of the own apparatus into a storage device at the time of the loss of a power supply. Furthermore, the information processing apparatus duplicates a difference of the state of the own apparatus at a predetermined time interval. Furthermore, the information processing apparatus estimates the time period needed to duplicate the difference. Then, the information processing apparatus determines whether the estimated time period is longer than the time period for which a battery operates the information processing apparatus at the time of the loss of the power supply. When the information processing apparatus determines that the estimated time period is longer than the time period for which the battery operates the information processing apparatus, the information processing apparatus reduces the time interval of the duplication.

主权项

1. An information processing apparatus that duplicates the state of the own apparatus into a storage device at the time of the loss of a power supply, the information processing apparatus comprising:
a duplicating unit that duplicates, in the storage device at a predetermined time interval, a difference of the state of the information processing apparatus; an estimating unit that estimates the time period needed by the duplicating unit to duplicate the difference; a determining unit that determines whether the time period estimated by the estimating unit is longer than the time period for which a battery that supplies electrical power to the information processing apparatus at the time of the loss of a power supply operates the information processing apparatus; and an updating unit that updates, when the determining unit determines that the time period estimated by the estimating unit is longer than the time period for which the battery operates the information processing apparatus, the time interval for which the duplicating unit executes the duplication to a smaller value.
