  • Patent number: 12105972
    Abstract: A snapshot virtual device (SS-VDEV) is prepared for each snapshot family (SS-Family) and a deduplication virtual device is prepared apart from the SS-VDEV. When the same data is in a plurality of VOLs of the SS-Family, a storage system maps a plurality of addresses of the same data among the plurality of VOLs to address of the SS-VDEVs of the SS-Family. When duplicated data is in two or more SS-VDEVs, the storage system maps two or more addresses of the duplicated data of the two or more SS-VDEVs to addresses corresponding to the duplicated data among the deduplication virtual devices.

  • Patent number: 11820165
    Abstract: Disclosed is a printed object which, even if using a receptive layer that is difficult for a monomer in an active energy ray curable ink to penetrate, has excellent adhesion between the active energy ray curable ink and the receptive layer, and in which the amount of unreacted monomer dissipated from the printed object is low. This printed object includes an ink receptive layer laminated on a substrate surface and having an ink absorption rate of 100% or less, and an ink layer laminated on a surface of the ink receptive layer and made from an active energy ray curable ink which includes a polymerizable compound, wherein the glass transition temperature of the polymerizable compound is ?45-25° C.

  • Patent number: 11474732
    Abstract: Backup data equivalent to the maximum number of generations to be held can be secured even when backup data is locked. When locking of prohibiting overwrite of one or more storage areas is performed, a backup server prepares a new backup management table and uses the backup management table and an archive management table, which is the past backup management table, to store the backup data equivalent to the maximum number of generations to be held into a storage system.

  • Patent number: 11074003
    Abstract: A storage controller configures a plurality of logical volumes, a CDP meta volume that manages history information related to writing from a server system for the logical volumes, and a CDP data volume that stores data of the plurality of logical volumes. The storage controller searches for, if a restoration request including a restoration time is received, the restoration request having one of the plurality of volumes as a restoration target volume, history information of the restoration target volume from the CDP meta volume, copies, in a case in which an evacuation time of old data included in the searched history information of the restoration target volume is newer than the restoration time, an SEQ number of the searched history information as first restoration control information, and acquires old history information on the basis of a previous SEQ number of the restoration target volume from the CDP meta volume.
