1、设置并发执行rman备份

1）手工配置

run{

allocate channel c1 type disk;

allocate channel c2 type disk;

allocate channel c3 type disk;

backup database format ‘c:\rman\d_%U_%p.bak’

tag=’xifenfei’;

}

2)参数中配置

configure device type disk parallelism 3 backup type to backupset;

backup database format ‘c:\rman\d_%U.bak’ tag=’xifenfei’;

2、设置备份文件大小

run{ allocate channel c1 type disk maxpiecesize 100m;

backup database format ‘c:\rman\test_%U_%p.bak’ filesperset 2 maxsetsize 500m;}

note：maxpiecesize–单个备份文件大小

filesperset–一个backset中含有的datafile的数量

maxsetsize–backset的大小

3、备份控制文件

1）配置自动备份

configure controlfile autobackup on;

RMAN> CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR

DEVICE TYPE DISK TO ‘c:\rman\cl_%F.ctl’;

2）备份时顺带备份

backup datafile 5 format ‘c:\rman\d_%U.bak’

include current controlfile;

4、一次备份多份（最多四份）

1）直接指定

backup copies 2 datafile 5 format

‘c:\rman\%U.bak’,'c:\temp\%U.bak’;

2）配置文件中指定

CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 2;

backup datafile 5 format ‘c:\temp\t_%U.bak’,'c:\rman\t_%U.bak’;
