高级 rman 备份问题求助

[hem]

备份脚本：
#!/bin/sh
source /home/oracle/.bash_profile

cd $ORACLE_HOME/bin

./rman target / catalog rman/rman@244 msglog=/home/oracle/work/log/rman_bk_L0_`date '+%Y%m%d%H%M%S'`.log <<EOF

run {
allocate channel c1 type disk;
backup incremental level 0 filesperset 5 tag 'dbL0' format '/mnt/raid/rman_bk/ora_o_%d_%t%s%p%u' database skip readonly include current controlfile;
sql 'alter system archive log current' ;
backup(archivelog all format '/mnt/raid/rman_bk/ora_a_%d_%t%s%p%u');
release channel c1;
}

list backup;
exit;

EOF


数据文件 控制文件 Spfile 文件都成功备份完毕，可是以前的归档日志都被我删了，新的归档日志还保留着，以后恢复是否还能完全恢复，还是只能恢复到当前时间点？
备份日志如下：

为什么是从1_5084.dbf 开始 而不是从1_1.dbf 开始

[xiaolife]

如果你在1_5084.dbf之后做了全备份而且以后的归档日志都在，就能完全恢复。
但从上面来看，你在1_5084.dbf之前做了全备份，而且以后的归档日志已经丢了，所以只能恢复到1_5084.dbf那个时间之前。
用resetlog重起数据库，并进行全库备份，这样以后的操作就没问题了。但之前的备份都没用了

能给我一个全数据库备份的脚本吗？ 备份完毕之后以前的日志就可以删除了吧。

备份脚本：改成这样 它还会提示以前备份的归档日志不存在吗？
#!/bin/sh
source /home/oracle/.bash_profile

cd $ORACLE_HOME/bin

./rman target / catalog rman/rman@244 msglog=/home/oracle/work/log/rman_bk_L0_`date '+%Y%m%d%H%M%S'`.log <<EOF

run {
sql 'alter system archive log current' ;
allocate channel c1 type disk;
backup database filesperset 5 tag 'dbFull' format '/mnt/raid/rman_bk/ora_o_%d_%t%s%p%u'
plus archivelog format '/mnt/raid/rman_bk/ora_a_%d_%t%s%p%u'
delete all input ;
release channel c1;
}

list backup;
exit;

EOF

[hem]

完全备份脚本 这样可以吗？
run {
allocate channel c1 type disk;
backup full tag 'dbfull' filesperset 5 format '/mnt/raid/rman_bk/ora_o_%d_%t%s%p%u' database ;
sql 'alter system archive log current' ;
backup filesperset 3 archivelog all delete input;
release channel c1;
}
