ABSTRACT:
One or more computer systems, a carrier medium, and a method are provided for backing up data using a backup server. The user may instruct backup software on a backup server to identify a second computer system (other than the backup server) as the parent computer system of the backed-up files. The backup software may receive the name of this second computer system as input, and the backup software may then output the name to a catalog during the backup process. When the backed-up data is restored, the catalog may be used to identify the parent of the backed-up data as the second computer system. In one embodiment, the data to be backed up may be part of a mirror which comprises substantially the same data as an original data volume. A carrier medium may include program instructions which, when executed, cause the above operations on one or more computer systems.
