The current business model of modern companies is increasingly dependent on information technology. Thus, it is necessary to keep security copies of the data (backup) which may be used to restore them after a data loss event. On the other hand, this dependence encourages strong competition among suppliers and this leads to new releases of computing commodities, seeking competitive advantages. In this paper, it is usual for corporations to deploy more than one DBMS to store their data, creating heterogeneous environments, and creating difficulties for data interoperability. Current DBMSs use proprietary backup formats and this means that other tools cannot access their data.
