ABSTRACT:
Provided is a storage system in which a transaction of a database is quiesced, a pair of a first volume and a second volume is split so as to make settings to allow an access to be made only to the database in the first volume, the transaction is then released from the quiescent state, a sparse space is specified in the database stored in the second volume, only the specified sparse space in the second volume is partially reorganized, and the contents of the partially reorganized second volume are copied to the first volume such that the first volume and the second volume are resynchronized with each other to form the pair again.
