1. An information processing device, comprising:
a data processing section configured to:
control a data recording process on a library, wherein the library includes a data storage section of an archive device;
save first record data in a local cache section in response to a data recording request from an external device to the library;
measure an elapsed time after the first record data is saved in the local cache section;
record the first record data into the library from the local cache section in a case where the elapsed time exceeds a determined postponement time,
wherein the data recording process to record of the first data from the local cache section into the library is stopped, based on detection of re-access of the first record data at a time of execution of the data recording process;
compare a data volume of second record data to be recorded in the local cache section with an available capacity of the local cache section;
select specific data to be erased from the local cache section based on an erasure data selection algorithm in a case where a result of the comparison indicates that the data volume of the second record data exceeds the available capacity of the local cache section; and
erase the selected specific data from the local cache section.
