A storage system and snapshot method wherein after a first processor transfers data stored in a first data area to a second storage system, the first processor transfers a first marker stored in a first marker area to a second storage system so that the first marker is stored in a second marker area of a second volume, wherein a second processor checks whether the first marker stored in the second storage area of the second volume corresponds to a second marker designated, and wherein, if the first marker stored in the second storage are of the second volume is a second marker designated, the second processor creates a snapshot of the data that is stored in the second data area, in a third storage volume.
