Information processing device, computer-readable recording medium having stored therein information processing program, and information processing method

A non-transitory computer-readable recording medium having stored therein an information processing program for causing a computer to execute a process comprising:

• recording, for each data, time of a write access of the data to management information,
• when writing out data from the memory that stores data concerning a write access to a storage, determining a plurality of data as a group of overall compression based on the management information, the plurality of data having a difference of time of write accesses being equal to or less than a threshold value, and
• compressing the plurality of data corresponding to the determined group by an overall compression, and writing compressed data obtained through the overall compression to the storage.
