介绍一下参数
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 3 DAYS; --备份策略，保留3天的备份
CONFIGURE RETENTION POLICY TO REDUNDANCY 7; --备份策略，保留7个备份
这两个备份策略只能两个取一，不能共存。

CONFIGURE BACKUP OPTIMIZATION ON;                         --备份优化打开，不知道oracle为什么不默认打开
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default          --备份设备设备disk为磁盘,sbt为磁带
CONFIGURE CONTROLFILE AUTOBACKUP ON;                      --控制文件备份是否自动备份，意思是说备份数据库的同时是否自动备份控制文件
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO 'd:\backup\control_%F';  --控制文件备份的目录和格式
CONFIGURE DEVICE TYPE DISK PARALLELISM 2 BACKUP TYPE TO BACKUPSET; --备份的并行度和备份压缩
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1;      --备份的数据文件有几个副本
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1;   --备份的归档日志有几个副本
CONFIGURE CHANNEL 1 DEVICE TYPE DISK FORMAT   'D:\BACKUP\BACKUP_%U';
CONFIGURE CHANNEL 2 DEVICE TYPE DISK FORMAT   'D:\BACKUP\BACKUP_%U';  --分配通道，通道的备份目录
CONFIGURE MAXSETSIZE TO UNLIMITED; # default         --备份集的大小，这个还是UNLIMITED为好，因为我们总是无法估计备份集的大小
CONFIGURE SNAPSHOT CONTROLFILE NAME TO 'D:\ORACLE\PRODUCT\10.2.0\DB_1\DATABASE\SNCFBACK.ORA'; # default --备份文件的镜像
