摘要： A backup system and backup method with which the processing time can be shortened without increasing the overhead and burden on the system administrator in a two-stage backup.In a backup system which executes a two-stage backup, the storage apparatus searches for a secondary volume which can be paired with a primary volume on the basis of the pair create instruction, determines whether the volume size of the secondary volume obtained as a search result is greater than the volume size of the primary volume and, if the volume size of the secondary volume is greater than the volume size of the primary volume, sets the volume size of the secondary volume as the same size as the volume size of the primary volume without changing the substantial volume size of the secondary volume, and notifies the host of information on the set volume size of the secondary volume and information indicating that a pair has been created.
