ABSTRACT:
The system includes a host, a backup server, a storage system having a journaling capability described above and a media library system. The storage system makes snapshots for restoring with journal at predetermined intervals in accordance with established process. Moreover, in correspondence to an instruction of the 1st type from the backup server, the storage system generates a marker of the 1st type to make snapshot to be provided to the backup. The storage system makes and provides a snapshot to the backup server according to the process of the 1st intended marker. Then the backup server takes a backup data from the snapshot. Furthermore, in correspondence to an instruction of the 2nd type from the backup server, the storage system generates a marker of the 2nd type to stop replication in the storage system. The storage system provides a quiescence image of a volume according to the process of the 2nd intended marker. Then the backup server takes a backup data from the quiescence image.
