RMAN 中delete exipired 和 delete obsolete 的区别

elete expired If you run CROSSCHECK, and if RMAN cannot locate the files, then it updates their records in the RMAN repository to EXPIRED status. You can then use the DELETE EXPIRED command to remove records of expired backups and copies from the RMA

[转]Oracle DB 使用RMAN创建备份2

归档备份:概念 归档备份:概念 如果需要在指定时间内保留联机备份,RMAN 通常会假定用户可能需要在自执行该备份以来到现在之间的任意时间执行时间点恢复.为了满足这一要求,RMAN 会在此时段内保留归档日志.但是,可能仅需要在指定的时间(如两年)内保留特定备份(并使其保持一致和可恢复).用户不打算恢复到自执行该备份以后的某一时间点,只是希望能够正好恢复到执行该备份的确切时间.此外,用户还需要维护保留策略以使备份区井然有序,因此无法使备份恢复到两年前.为了满足保留数据的商业或法律要求,通常需要这么做

Oracle 学习之RMAN（一）

Recovery Manager(RMAN)是Oracle提供的一个实用工具,使用RMAN可以对Oracle数据库进行备份.还原.恢复等.RMAN还可以自动管理Oracle的备份策略.RMAN提供了命令行与图形界面两种访问方式.我们主要学习命令行方式操作RMAN. 进入RMAN非常简单,执行在OS环境下敲入rman命令即可. [[email protected] ~]# su - oracle 11gdg-> rman Recovery Manager: Release 11.2.0.3.0 -
