Abstract
An information processing apparatus includes an identifying unit and a determining unit. The identifying unit identifies write requests received from the same source at intervals each within a predetermined time period. The determining unit determines to perform a write operation employing first-method deduplication for a preset number of write requests selected amongst the write requests in reverse chronological order according to reception times thereof, and perform the write operation employing a second-method deduplication for the remaining write requests. The first-method deduplication includes postprocess deduplication while the second-method deduplication includes inline deduplication. The preset number is set based on a minimum interval of write requests sequentially issued from the source and time periods in the first-method deduplication and the second-method deduplication from the reception of each write request to the transmission of the response.
