Abstract: A processor is configured to, in a case where a distribution rule is changed, issue an inquiry as to whether or not an object having same identification information as a received object is stored to at least one storage node as a distribution destination corresponding to a past distribution rule, in a case where a response indicating that the object having the same identification information as the received object is stored is made from any storage node, distribute the received object to the storage node storing the object having the same identification information as the received object, and in a case where the response indicating that the object having the same identification information as the received object is stored is not made from any storage node, distribute the received object to any of the plurality of storage nodes in accordance with a most recent distribution rule.

Abstract: An information processing device includes at least one processor. The processor performs, in a case where an address relative value between a first address value indicating an end position in a tape running direction of recorded data which is data recorded in a first partition of a magnetic tape having the first partition in which data is recorded and a second partition in which metadata corresponding to the data is recorded and a second address value indicating an end position in the tape running direction of latest metadata recorded in the second partition is within a predetermined range, control to record metadata corresponding to recorded data recorded after the latest metadata is recorded, in the second partition.

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: A transfer device is a transfer device that distributes and transfers a plurality of pieces of data to a plurality of information processing devices that perform control to record data on a magnetic tape, in which the transfer device transfers data to the plurality of information processing devices such that the number of pieces of data is leveled between the plurality of information processing devices, and transfers a plurality of pieces of data of which a value indicating a probability that a plurality of pieces of data are read within a predetermined period is a threshold value or greater, to the same information processing device.

Abstract: An information processing device performs control to record, out of a plurality of pieces of data to be recorded on a plurality of magnetic tapes, a data group in which a value corresponding to a size of a data group for which a storage period is within a predetermined range is equal to or more than a threshold value and a data group in which the value is less than the threshold value, on magnetic tapes different from each other.

Abstract: An information processing device performs control to record identification information of at least a part of a plurality of magnetic tapes belonging to a magnetic tape pool, on the plurality of magnetic tapes or on a recording medium except for the magnetic tapes that is provided in a plurality of magnetic tape cartridges including the plurality of magnetic tapes, respectively.

Abstract: An information processing device selects, in a case where a plurality of pieces of data are collected and transmitted to a tape drive to be recorded on a magnetic tape, one mode of a first mode of transmitting a data group obtained by collecting the plurality of pieces of data without compression, to the tape drive, a second mode of transmitting a compressed data group in which the data group obtained by collecting the plurality of pieces of data is compressed, to the tape drive, or a third mode of transmitting a data group obtained by collecting a part of the plurality of pieces of data and remaining data, in which the part of the plurality of pieces of data is compressed and the remaining data is not compressed, to the tape drive, and transmits a data group generated in accordance with the selected mode, to the tape drive.

Abstract: An information processing device (10) includes at least one processor. The processor divides data with a certain size or larger, which is specified on the basis of a read-out history, into a plurality of pieces of partial data, and performs control to distribute and record the plurality of pieces of partial data with respect to a plurality of magnetic tapes, respectively.

Abstract: An information processing device performs, in a case where, out of a plurality of magnetic tapes on which data is multiplexed and recorded, the number of the magnetic tapes which is equal to or more than a predetermined number of multiplexes are stored in a storage unit, first control to handle each magnetic tape stored in the storage unit, to be readable and writable, and performs, in a case where the number of the magnetic tapes which is less than the number of multiplexes are stored in the storage unit, second control to handle the magnetic tape stored in the storage unit, to be read-only.

Abstract: An information processing apparatus performs, in a case where an object including at least one of data or metadata related to the data is recorded in a magnetic tape, control of reading one or more object groups and one or more metadata groups recorded in the 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, and determines, in a case of recording the object groups in the first partition of a certain magnetic tape of a plurality of magnetic tapes different from the magnetic tape and recording the metadata groups in the second partition of the certain magnetic tape, for a set of the one or more object groups and the one or more metadata groups, a magnetic tape as a recording destination of the object groups and the metadata groups, from the plurality of magnetic tapes, according to a ratio between a size of the object groups and a size of the metadata groups.

Abstract: An information processing apparatus acquires a plurality of pieces of data having any one of a plurality of different attribute values, and performs control of recording the plurality of pieces of data in a magnetic tape in a contiguous sequence of pieces of data having one of different attribute values or data groups having different attribute values.

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 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.
