Abstract: An information processing apparatus receives a first object list corresponding to a first prefix from each of a plurality of storage nodes, compares, for an object that has a delimiter at the end among objects included in each of the first object lists, a portion obtained by excluding the delimiter at the end with a second prefix included in the first object list received from the other storage node, and removes redundancy in a case where the portion obtained by excluding the delimiter at the end and the second prefix are redundant with each other and then transmits a second object list obtained by merging each of the first object lists to a user terminal.

Abstract: An information processing apparatus refers to a first variable in a case where an object saving instruction is received, sets a second variable to a value indicating that an object is being saved in a case where a state of a saving destination of an object is a normal state, refers to the second variable in a case where a deletion instruction of a saving destination of an object is received, sets the first variable to a value indicating that a state of the saving destination is a deletion start state and then refers to the second variable again in a case where an object is not being saved, responds that deletion of the saving destination is not possible in a case where an object is being saved.

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 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 apparatus includes at least one processor and distributes an object to be stored to any of a plurality of storage nodes in accordance with a distribution rule set in advance. The processor is configured to receive the object to be stored, specify a distribution rule to be applied based on a first part that is included in identification information of the received object and that is associated with the distribution rule, and distribute the received object to any of the plurality of storage nodes in accordance with the specified distribution rule.

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 sequentially receives a first object list corresponding to a first prefix from each of a plurality of storage nodes, removes, in a case where a processed storage node exists, a second prefix held by the processed storage node from the first object list received from a storage node being processed, receives a second object list including objects of which the number is decreased by removal of the second prefix from the storage node being processed, and transmits, to a user terminal, an object list obtained by adding the second object list to the first object list from which the second prefix is removed.
