Mirror database and redundant server

The mirror database and redundant server component provides an alternative duplication mechanism in case of failures and errors of the primary server. The mirror database creates a real-time copy of the system database on the redundant server. In the event of a failure from the primary server, the mirror database launches the redundant server which supports all the features and functionality of the primary server, except the card gateway program. After the primary server returns online, all archives are merged and the entire database is copied or merged from the redundant server.
