A method of managing storage implemented in a storage management device that manages storage to which access for information is made by a requesting processing apparatus, including randomly obtaining a prescribed number of data units from among data units that constitute the information from the storage, calculating a sample unit duplication ratio, which is a ratio at which the obtained data units duplicate each other, estimating an overall data unit duplication ratio, which is a ratio at which all data units stored in the storage duplicate each other, by using a prescribed function that utilizes the calculated sample unit duplication ratio, and outputting the estimated overall data unit duplication ratio to an output device. |
