--RMAN备份介质的移动与再恢复测试
---------------------------------------------------------2013/09/21
由于目前生产环境中没有集中的备份条件,所以备份要考虑到可以移动再恢复性.这里要测试的就是,RMAN全部备份的介质,我关注是否可以定期的移动到其他存储介质中,到要恢复的时候再拿过来.
1. 备份现有数据库和控制文件.
RMAN> backup database include current controlfile;
2. 移走备份集,到另外的目录/u01/app/oracle/flash_recovery_area/august/AUGUST/backupset/o1_mf_nnndf_TAG20130920T235853_93tjxkb9_.bkp
3. 查看过期的备份介质.
RMAN> report obsolete;
RMAN retention policy will be applied to the command
RMAN retention policy is set to redundancy 1
Report of obsolete backups and copies
Type Key Completion Time Filename/Handle

4. 删除过期的备份介质.
RMAN> delete obsolete(nopormt指定无需确认立即删除)
5. 由于我们已经讲备份的介质移走了，但是RMAN的备份记录中依然存在，清除这些信息。
RMAN> crosscheck backup;
using channel ORA_DISK_1
crosschecked backup piece: found to be 'EXPIRED'
backup piece handle=/u01/app/oracle/flash_recovery_area/august/AUGUST/backupset/2013_09_20/o1_mf_nnndf_TAG20130920T235853_93tjxkb9_.bkp RECID=5 STAMP=826675137

7. 关闭数据库删除控制文件和数据文件。
8. 启动数据库到nomount下，恢复控制文件。
RMAN> startup nomount;

那如何使用这个备份集恢复呢？
10. 需要先将备份集catalog到RMAN备份记录中去。
RMAN> catalog start with '/u01/app/oracle/flash_recovery_area/august/AUGUST/backupset/o1_mf_nnndf_TAG20130920T235853_93tjxkb9_.bkp';

12. 进行介质恢复。

所以总结来说，利用备份集的移动是没有问题的，恢复时只需要重新编目到备份集信息中即可。 [catalog start with ‘dir’]
