<p>A back-up system. The back-up system stores a back-up image having data from at least one DASD. The logical files and disks backed-up are synchronized, even if the back-up set spans multiple DASDs. The synchronization may be initiated by the CPU or a control device. The level of granularity for back-ups includes logical disks, and is not limited to files. The back-up image includes configuration information so that a restore system may arrange a DASD, used by the restore, to automatically have the same configuration. The back-up image also includes the DASD firmware, thus further improving the cloning of the backed-up DASD.</p> |
