Abstract: An information processing apparatus calculates, in a case of adding a new magnetic tape to a storage pool, the number of magnetic tapes to be added to the storage pool such that a free capacity of the storage pool after addition of the new magnetic tape is set to be equal to or larger than a capacity obtained by adding, to an assumed value of a total capacity of data to be recorded in the storage pool, an excess according to the number of pieces of parallel processing when recording data in the storage pool, the number being equal to or smaller than a number obtained by multiplying the number of magnetic tapes satisfying an insufficient capacity of the storage pool by the number of pieces of parallel processing, and performs control of adding the calculated number of new magnetic tapes to the storage pool.

Abstract: An information processing device performs control to record deletion information indicating that an object with a designated object ID has been deleted, on a recording medium, in a case where a specific object ID is designated and an instruction to delete the object is input, for a magnetic tape on which an object that includes data and metadata related to the data and that is assigned an object ID as identification information is recorded, the object being assigned an object ID in a case where the object is updated different from an object ID of the object before the update.

Abstract: An information processing apparatus determines, for each of packed objects recorded on one data-migration-source magnetic tape, whether or not to regenerate the packed objects by using objects included in the packed objects, generates a second packed object by using objects included in a first packed object determined as being regenerated, performs control of distributing and recording a plurality of second packed objects and parity data on a plurality of magnetic tapes, and performs control of recording a packed object determined as not being regenerated on a magnetic tape different from the data-migration-source magnetic tape.

Abstract: An information processing device includes at least one processor. The processor performs, in a case where a size of data recorded in a data partition (DP) of a magnetic tape (30) having the data partition (DP) in which data is recorded and a reference partition (RP) in which metadata corresponding to the data is recorded, on the magnetic tape (30), reaches a predetermined value, control to record metadata corresponding to the recorded data in the reference partition (RP).

Abstract: An information processing apparatus calculates, in a case where an object including at least one of data or metadata related to the data is recorded in a magnetic tape including a first partition in which one or more objects are to be recorded and a second partition in which pieces of the metadata are to be recorded, a second ratio as a ratio between a size of the first partition and a size of the second partition in the magnetic tape by using a first ratio as a ratio between a total size of the objects and a total size of the pieces of the metadata.
