Abstract:
In a storage apparatus, when a received backup instruction is a backup start instruction, a control unit performs a backup process from a position indicated by an available area start pointer. When the received backup instruction is a backup end instruction, the control unit releases an allocated backup area. In addition, the control unit determines whether the released backup area is adjacent to a position indicated by an available area end pointer. If determining that the released backup are is adjacent to the position indicated by the available area end pointer, the control unit moves the available area end pointer indicating the end of an available area to the end of the released backup area.
