Abstract
The present invention provides a backup method that makes it possible to specify the recovery-enabled time of an application even in a case where a backup has been performed without staticizing the application. In response to a first instruction from a management computer, a storage system backs up a first volume to a second volume at a first time while a first host computer continues to process an application. In response to a second instruction from the management computer, a second host computer reads out the data of the second volume and acquires a second time that is the time at which the application is recovery-enabled. The management computer stores the relationship between the backup and the second time in backup catalog information.
