Study ORACLE database backup and restore based on the RMAN technique

介绍了采用RMAN实现ORACLE数据库备份恢复的功能特点及实现过程,探讨了RMAN备份恢复机理,描述了差异增量备份和累积增量备份工作模式,给出了备份/恢复的常见脚本.合理制定RMAN备份恢复策略,可以提高备份恢复的有效性,优化数据库性能.

This text introduces the realization of the function characteristic and the process of the ORACLE database backup and restoration by adopting RMAN, inquires into the RMAN backup restoration mechanism, describes the work mode of the differential incremental backups and cumulative incremental backups, provides backup/restoration of common script. Set down RMAN backup and resume policy in reason, it can improve the validity of backup and resume, optimize the capability of the database.
