rman备份归档的问题，谢谢，如果回答的好，有加分~

就是，我已经备份归档了，下次rman备份的时候，还会备份那些上次备份过得归档日志么？
还有一个问题，我想在备份完归档日之后，将归档日志移动（剪切）到其他地方，在rman中如何实现呢？
附我的rman脚本：
orabackup0：
run {allocate channel t1 type disk maxpiecesize = 3G;
backup
incremental level 0
filesperset 10
format 'c:\rman\db_%d_%t_%s_%p'
(database include current controlfile);
release channel t1;}
run {allocate channel a1 type disk maxpiecesize = 3G;
sql 'alter system archive log current';
crosscheck archivelog all;
backup
filesperset 10
format 'c:\rman\arch_%d_%t_%s_%p'
archivelog all delete input;
Backup current controlfile;
release channel a1;
}

orabackup1：
run {allocate channel t1 type disk maxpiecesize = 3G;
backup
incremental level 1
filesperset 10
format 'c:\rman\db_%d_%t_%s_%p'
(database include current controlfile);
release channel t1;}
run {allocate channel a1 type disk maxpiecesize = 3G;
sql 'alter system archive log current';
crosscheck archivelog all;
backup
filesperset 10
format 'c:\rman\arch_%d_%t_%s_%p'
archivelog all delete input;
Backup current controlfile;
release channel a1;
}

你的脚本不是自己写的吧？
1、倒数第4行 delete input其实就是备份后删除，你下次备份的时候，归档日志已经没了，根本没法再备份。
我看你的意思是想备份了然后清理一下归档日志，归档日志大量堆积会产生不利影响。其实这个脚本已经实现了。

这个需求可以通过 backup archivelog all not backed up; 语法来实现。 使用该命令如果遇到 满足 not backed up xx times 的归档才会备份，否则即便该归档仍在disk上未被删除 也不会重复备份， 避免了重复备份带来的问题，也无需每次备份均删除磁盘上的归档文件。 rman> backup archivelog all not backed up;
