copies备份镜像命令咨询

lujiaguai

上课提到，备份镜像，只能两路都放在磁盘上，不可以一路闪回区，一路磁盘
这里不知道有没有记错？

2路都放在磁盘的命令如下写，但是报错，是哪里写错了？
run
{
allocate channel c1 device type disk format  '/u01/app/oracle/backupcopies/b1/image_%u.bkp'
'/u01/app/oracle/backupcopies/b2/image_%u.bkp';
backup copies 2 tag '0620.userscopies2' incremental level 0 tablespace users;
}


文件目录已创建
[oracle@station200 ~]$ cd /u01/app/oracle/backupcopies
[oracle@station200 backupcopies]$ ls
b1  b2

已解决
1，双引号
2，逗号分隔

run
{
allocate channel c1 device type disk format  "/u01/app/oracle/backupcopies/b1/image_%u.bkp",
"/u01/app/oracle/backupcopies/b2/image_%u.bkp";
backup copies 2 tag '0620.userscopes2' incremental level 0 tablespace users;
}
