Abstract:
1. A data backup management system, which is coupled to a backup source storage apparatus and a backup target storage apparatus, and manages a data backup from the backup source storage apparatus to the backup target storage apparatus, wherein the backup source storage apparatus includes a backup source volume to be accessed by a host computer, the backup target storage apparatus includes at least one or more backup target volumes, and an intermediate volume which is located between the backup source volume and the at least one or more backup target volumes, and which serves as a backup target for the backup source volume and as a backup source for the at least one or more backup target volumes, the data backup management system comprises: a communication interface circuit for coupling to the backup source storage apparatus and the backup target storage apparatus via a communication line; a memory for storing a predetermined computer program and a management table; and a microprocessor which executes the predetermined computer program by reading the program from the memory, and the microprocessor: controls a remote copy from the backup source volume to the intermediate volume, and a local copy from the intermediate volume to the at least one or more backup target volumes; creates, in a case where a fault relating to the remote copy or to the local copy is detected, a management screen displaying the at least one or more backup target volumes as a candidate for a restore source volume; and edits, in a predetermined case, part of information on the at least one or more backup target volumes displayed on the management screen on the basis of information relating to the intermediate volume.
