Information processing device and information processing method

An information processing method, comprising:

• in an archive device:
• controlling a data recording process on a library, wherein the library includes a data storage section of the archive device;
• saving first record data in a local cache section in response to a data recording request from an external device to the library;
• measuring an elapsed time after the first record data is saved in the local cache section;
• recording 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;
• comparing a data volume of second record data to be recorded in the local cache section with an available capacity of the local cache section;
• selecting 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
• erasing the selected specific data from the local cache section.

A non-transitory computer-readable medium having stored thereon, computer-executable instructions which, when executed by a processor, cause the processor to execute operations, the operations comprising:

• in an archive device:
• controlling a data recording process on a library, wherein the library includes a data storage section of the archive device;
• saving first record data in a local cache section in response to a data recording request from an external device to the library;
• measuring an elapsed time after the first record data is saved in the local cache section;
• recording 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;
• comparing a data volume of second record data to be recorded in the local cache section with an available capacity of the local cache section;
• selecting specific data 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
• erasing the selected specific data from the local cache section.
