  • Storage control apparatus, computer readable medium and method including creating snapshots and difference storage areas for respective volumes in a consistency group
    Patent number: 9665435
    Abstract: A storage control apparatus controls storage units in a storage apparatus and includes a memory unit that stores group information identifying a copy-source volume group belonging to a consistency group; and a control unit that creates based on the group information, snapshots of respective volumes of the volume group for a given time point; creates respective difference storage areas to store, as difference data, update data for the respective volumes after the given time point; and transfers to a copy-destination storage apparatus, data of the snapshots of the respective volumes. The control unit further creates snapshots of the respective volumes at an arbitrary time point after the given time point; creates respective difference storage areas to store, as difference data, update data for the respective volumes after the arbitrary time point; and transfers to the copy-destination storage apparatus, the difference data of the respective volumes for the arbitrary time point.
