INFORMATION ACCUMULATION DEVICE AND INFORMATION ACCUMULATION SYSTEM AND INFORMATION ACCUMULATION METHOD

摘要

To suppress reduction of acquisition speed of information at either accumulation timing.SOLUTION: A device comprises an accumulation control part 103 accumulating inputted information into a first accumulation part 101, an accumulation management part 104 that determines whether the information accumulated in the first accumulation part 101 is copied to a second accumulation part 100 B based on a connection state and an accumulation state of the second accumulation part 100B accumulating backup data and outputs permission information permitting copy processing in a constant period, and a copy control part 105 that copies the information accumulated in the first accumulation part based on the permission information outputted in the constant period and accumulates the information into the second accumulation part.SELECTED DRAWING: Figure 1
