<p>The invention relates to a database system (1) comprising a database logic (5) adapted to perform database processing and a backup interface (20) for external backup, wherein the backup interface (20) is adapted to connect the database system (1) to a plurality of different external backup systems (11) and wherein the backup interface (20) is adapted to receive one or more plugged-in functions (12) of the different external backup systems (11). The database logic (5) communicates with the backup interface (20) using only a predefined set of extension points (6, 7, 8, 9, 10, 17), at least some of the extension points (6, 7, 8, 9, 10, 17) being adapted for being implemented by one or more of the plugged-in functions (12) of each of the different external backup systems (11).</p> |
