- For the problems of big backup files and long recovery time after traditional real-time backup method has been backup for a long time, A new method base on RMAN and Streams technology is presented in this paper. This method uses the Streams technology to make real-time backup for database. in the meantime, Timing detect the busy degree of the database system. When the database system is not busy and real-time backup file is larger than the preset threshold, using RMAN for a physical backup. In the recovery, this method implements physical recovery at first, and then, real-time backup file’s SQL acts on database. This method avoids the disadvantages of real-time backup file growing over time, recovering from the beginning, and effectively solves the problems of big real-time backup files and long recovery time.
