A storage management apparatus includes a prevention instructing unit and an execution instructing unit. The prevention instructing unit transmits an update prevention instruction to prevent data in a backup source volume from being updated by an information processing apparatus. After the update prevention instruction is transmitted, the execution instructing unit transmits to the storage apparatus an execution instruction to cause the storage apparatus to execute a snapshot creation process and a backup process. The snapshot creation process creates a snapshot of the backup source volume using a copy-on-write scheme. The backup process copies updated data among the data in the backup source volume to a backup destination volume.

Provided are a vehicle steering device and the like, which are capable of converging a lateral displacement at a forward gazing-point distance to a target travel line with simple control. A target travel line for a vehicle to travel by following a travel path recognized from an image taken by a camera or the like is set. A lateral speed, which is a change amount of the lateral displacement that is a difference between a position of the target travel line at the forward gazing-point distance and a position of the vehicle, is controlled so that the lateral displacement is reduced. A target steering angle is calculated based on the lateral speed, and a steering angle of the vehicle is controlled based on the calculated target steering angle.
