摘要：
In one example, a method for detecting failover in a database mirroring system that begins when a determination is made as to the time of the most recent backup of the principal database. Next, the time of the most recent backup of the mirror database is determined. Then, the time of the most recent backup of the principal database is compared to the time of the most recent backup of the mirror database to determine if the principal database was backed up most recently. Finally, if the mirror database is the database that was backed up most recently, it is established that failover has occurred.
