Abstract: An information processing apparatus performs first migration processing of migrating data from a relatively-old-generation magnetic tape included in one storage pool of a plurality of storage pools to relatively-new-generation magnetic tapes included in each of the plurality of storage pools in a case where the number of tape drives which are available for data migration is equal to or larger than a threshold value, the tape drives being relatively-new-generation tape drives among a plurality of generations of tape drives, and performs second migration processing of migrating data from migration-source magnetic tapes as relatively-old-generation magnetic tapes included in the storage pool to migration-destination magnetic tapes of which the number is smaller than a multiplicity in a case where the number of the tape drives is smaller than the threshold value.

Abstract: An information processing apparatus performs first migration processing of migrating data from a relatively-old-generation magnetic tape included in one storage pool of a plurality of storage pools to relatively-new-generation magnetic tapes included in each of the plurality of storage pools in a case where a total value of free capacities of the relatively-new-generation magnetic tapes in each of the plurality of storage pools is equal to or larger than a threshold value, and performs second migration processing of migrating data from a plurality of migration-source magnetic tapes included in the storage pool to migration-destination magnetic tapes of which the number is smaller than the number of the migration-source magnetic tapes in a case where the total value is smaller than the threshold value.

Abstract: In a case of performing control of migrating data from a relatively-old-generation magnetic tape as a migration-source magnetic tape included in one storage pool of the plurality of storage pools to relatively-new-generation magnetic tapes as migration-destination magnetic tapes included in each of the plurality of storage pools, an information processing apparatus excludes, from migration targets, data recorded in a relatively-new-generation magnetic tape included in a storage pool to which the migration-destination magnetic tape belongs.

Abstract: An information processing apparatus executes processing of making sizes of a plurality of pieces of data the same by adding dummy data to data other than data having a maximum size among the plurality of pieces of data, generates parity data based on the plurality of pieces of data to which the dummy data is added, and selects the magnetic tapes as recording destinations of the plurality of pieces of data and the parity data from the plurality of magnetic tapes such that a difference in a size of at least one of the dummy data or the parity data to be recorded on each of the plurality of magnetic tapes is minimized.

Abstract: An information processing apparatus performs, in a case where the same data is recorded in each of a plurality of storage pools each of which includes a plurality of generations of magnetic tapes and each for which a priority representing a degree to which a relatively-new-generation magnetic tape is used with priority is set, control of recording data recorded in a relatively-old-generation magnetic tape of a storage pool of which the priority is relatively high, in a relatively-old-generation magnetic tape of a storage pool of which the priority is relatively low.

Abstract: An information processing apparatus selects a magnetic tape as a data migration target from among a plurality of migration-source magnetic tapes based on an index value correlated with a read frequency of valid data recorded in the magnetic tape, the index value being calculated for each of the magnetic tapes, specifies valid data recorded in the selected magnetic tape, and performs control of migrating the valid data to a migration-destination magnetic tape.

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 apparatus reads definition information that is common to a plurality of magnetic tapes and defines a plurality of pieces of data included in archive data, generates the same number of pieces of the archive data as the number of the magnetic tapes based on the definition information, the archive data being obtained by grouping the plurality of pieces of data, and performs control of recording the plurality of pieces of generated archive data on the plurality of magnetic tapes in one-to-one correspondence.

Abstract: An information processing apparatus determines a data migration timing of a magnetic tape as a data migration source based on a transition of information related to pieces of valid data included in a data group recorded in each of a plurality of the magnetic tapes, and performs control of migrating the pieces of valid data recorded in the magnetic tape as a data migration source to a magnetic tape as a data migration destination at the determined timing.
