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.

Abstract: An information processing apparatus includes at least one processor and stores an object to be stored in any of a plurality of storage nodes in accordance with a distribution rule set in advance. The processor is configured to, in a case where the object to be stored is a new object that is newly created, distribute the new object in accordance with a distribution rule set at a point in time at which a storage request of the new object is made. The processor is configured to, in a case where the object to be stored is an update object that is an update of an existing object stored in any of the plurality of storage nodes, distribute the update object to the same storage node as a storage node in which the corresponding existing object is stored, in accordance with a distribution rule applied to the corresponding existing object.

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.
