Wuhan Water Corporation (Hereinafter referred to as 'Wuhan Water') is a state-owned conglomerate that manages the water supply and sewage treatment of urban areas of Wuhan city (except Qingshan District). It produces 3,750,000 tons of water per day and serves over 1,125 km². As its reliability on electronic systems grow, it becomes increasingly important to ensure data security and maintain safe operation. Using standalone server and magnetic tape station could obviously no longer meet the demands of Wuhan Water, which requires a disaster recovery solution that integrates remote backup, business takeover and disaster recovery drill. Potential threats against data security such as hardware damage, blackout, faulty operation, natural disaster and data migration between stations could all jeopardize the main server and cause a string of consequences.

While virtualization technology, compared with manual physical backup, enjoys a lot of advantages, such as low cost, flexibility, efficiency, environment-friendliness and ease of management. After thorough consideration, Scutech has developed a disaster recovery solution for Wuhan Water that is high-availability, extendable and easy to operate.

The topology is as follows:

The solution allows multiple backup methods for various application systems like file system and code table system; it guarantees high availability for business systems, DBackup could instantly activate backup server to take over business in case of system failure; it also provides disaster recovery drill function,so Wuhan Water can perform a disaster recovery drill monthly to verify the availability of backup data. It provides comprehensive protection of Wuhan Water’s business server and avoids business catastrophe due to data loss.
