Chapter11-RMAN Backups

1、只有在RMAN下可以实现增量备份

2、Backup File Types

• Tablespaces
• Datafiles(current or copy)
• Control file(current or copy)
• Spfiles
• Archived logs
• Backup Sets

3、要执行RMAN数据库备份，必须要求Oracle Database Server必须处于archive mode下；

RMAN进行备份的时候，会将Online redo log files 进行一次alter system switch log file,然后再进行备份操作；把online redo log file的内容，写到archive log file里面，然后备份归档日志就可以了；因此RMAN不对online redo log file 做备份.

4、Backup Issues

• Backup datafiles
• Backup tablespaces
• Backup the control file
• Backup the server parameter file
• Backup the archived log files
