Abstract
The invention provides a cloud data base system and a data management method that can reorganize a DB without stopping and without affecting business in a cloud. The cloud data base system includes a virtual machine provided by a cloud service, an object storage, and a volume configured to store a DB. When the DB is reorganized, the virtual machine switches an issue destination of an IO from a first pseudo device to a second pseudo device, and causes a replication function to create a replicated volume and causes the first pseudo device to reorganize the DB stored in the replicated volume, while causing the second pseudo device to continue to issue an IO to a replication source volume that is a volume storing the DB.
