    摘要: A copy source device includes bit map acquisition and bit map merge functions. In accordance with bit-map management information in which a bit map indicating the presence of written data is rounded, the bit map acquisition and bit map merger acquires required bit map from a copy destination device, and merges the acquired bit map to a corresponding bit map of the copy source device. The copy destination device includes bit-map management information updater. The bit-map management information updater updates bit-map management information indicating a write operation when the write operation has been performed during a copy suspend mode. During a copy resume mode, the copy source device requests the copy destination device to transfer the bit-map management information, and in response, the copy destination device transfers the bit-map management information.

    摘要: Pre-update data is copied from a first storage device onto a second storage device in response to an update instruction to update data on the backup target volume on the first storage device. A copy status of each data on the backup target volume is managed with position information of the data mapped thereto. If bad data is present in the data on the backup target volume, the position information indicating the position of the bad data is searched. In accordance with the copy status managed with the position information mapped thereto, it is determined whether the pre-update data of the bad data is stored on the second storage device.

    摘要: A lower part structure in a vehicle body rear part has a rear suspension frame disposed in rear of a fuel tank and in front of a spare tire and has a mechanism for causing jump up of the rear part of the spare tire under load application from the vehicle rear. The lower part structure is configured so that the center in the vertical direction of the front part of the spare tire is located so as to lap on the extension line of vertical width of a frame in the vehicle width direction of the rear suspension frame, and when the spare tire is moved to the vehicle front by a load applied from the vehicle rear, the spare tire comes into contact with the rear suspension frame directly or indirectly, whereby the rear part of the spare tire is pushed up with the rear suspension frame side being the center, and is turned in the longitudinal direction.
