Information processing apparatus, information processing method, and information processing program

An information processing method executed by a processor of an information processing apparatus, the method comprising:

• determining, for each of a plurality of packed objects recorded on one data-migration-source magnetic tape designated as a data migration target among a plurality of magnetic tapes on which the plurality of packed objects and parity data generated by using the plurality of packed objects are distributed and recorded, whether or not to regenerate the packed objects by using objects included in the packed objects, the plurality of packed objects being obtained by grouping one or more objects including data and metadata related to the data;
• generating a second packed object by using objects included in a first packed object determined as being regenerated;
• generating parity data by using a plurality of second packed objects;
• performing control of distributing and recording the plurality of second packed objects and the parity data on the plurality of magnetic tapes;
• and
• performing control of recording a packed object determined as not being regenerated on a magnetic tape different from the data-migration-source magnetic tape.

A non-transitory computer-readable storage medium storing an information processing program for causing a processor of an information processing apparatus to execute a process comprising:

• determining, for each of a plurality of packed objects recorded on one data-migration-source magnetic tape designated as a data migration target among a plurality of magnetic tapes on which the plurality of packed objects and parity data generated by using the plurality of packed objects are distributed and recorded, whether or not to regenerate the packed objects by using objects included in the packed objects, the plurality of packed objects being obtained by grouping one or more objects including data and metadata related to the data;
• generating a second packed object by using objects included in a first packed object determined as being regenerated;
• generating parity data by using a plurality of second packed objects;
• performing control of distributing and recording the plurality of second packed objects and the parity data on the plurality of magnetic tapes;
• and
• performing control of recording a packed object determined as not being regenerated on a magnetic tape different from the data-migration-source magnetic tape.
