ABSTRACT:
In order to make maintenance work of a storage apparatus system having redundant data easy, it is desirable to set a storage medium group sharing common redundant data at locations that can be easily identified. The system provides a storage apparatus system having transportable recording media. In the system when a failure occurs in a storage medium the data of the failed storage medium is recovered and then stored on a spare storage medium. The spare storage medium having the recovered data is then moved, by a robot, to a location that is closely related to a storage medium group sharing common redundant data with the failed storage medium.
