UCM environments, especially those that are integrated with Rational® ClearQuest®, can create complex relationships among a project’s VOBs and its Rational ClearQuest databases. Backing up related databases together describes ways in which you can schedule VOB and Rational ClearQuest database backups to minimize restore-time inconsistencies between them. Restoring one or more members of a set of related databases describes ways in which you can use checkvob –ucm to find and fix problems after restoring one or more members of a set of related databases (or any time an unexpected system or network event has caused an inconsistency in database relationships in a UCM environment.)
