linux自动运行rman增量备份脚本

一、增量备份脚本
0级备份脚本：红色部分为自定义的备份文件放置的目录

#script.:backupfull.sh
#creater:xyh
#date:2014-03-08
#desc:backup full database datafile in archive with rman
#connect database
export oracle_base=/u01/app/oracle
export oracle_sid=orcl
export oracle_home=/u01/app/oracle/product/10.2.0/db_1
export path=$oracle_home/bin:$path
rman target/ << eof_rman
run{
allocate channel c1 type disk;
backup incremental level 0 tag 'db0' format
'/home/oracle/rmanbackup/db0_%d_%t_%s' database include current controlfile;
sql 'alter system archive log current';
backup filesperset 5 format '/home/oracle/rmanbackup/cf0_%d_%t_%s' archivelog all delete input;
#filesperset 5表示备份集里面最多包含5个文件 
delete noprompt obsolete;
release channel c1;
}
# end

1级备份脚本

#script.:incrl.sh
#creater:xyh
#date:2014-03-08
#desc:backup full database datafile in archive with rman
#connect database
export oracle_base=/u01/app/oracle
export oracle_sid=orcl
export oracle_home=/u01/app/oracle/product/10.2.0/db_1
export path=$oracle_home/bin:$path
rman target/ << eof_rman
run{
allocate channel c1 type disk;
backup incremental level 1 tag 'db1' format
'/home/oracle/rmanbackup/db1_%d_%t_%s' database include current controlfile;
sql 'alter system archive log current';
backup filesperset 5 format '/home/oracle/rmanbackup/cf1_%d_%t_%s' archivelog all delete input;
#filesperset 5表示备份集里面最多包含5个文件 
delete noprompt obsolete;
release channel c1;
}
#end

二、使用linux的crontab设置自动执行备份

crontab -e

按enter后，可以像vi编辑器一样输入下面内容

0 1 * * 0 /home/oracle/backupfull.sh >>/home/oracle/backupfull.log
0 1 * * 3 /home/oracle/backupfull.sh >>/home/oracle/backupfull.log
30 1 * * 1-2 /home/oracle/incrl.sh >>/home/oracle/incr.log
30 1 * * 4-6 /home/oracle/incrl.sh >>/home/oracle/incr.log

查看crontab内容：crontab -l
注：上面意思是把全库备份日志写到/home/oracle/backupfull.log文件中，而增量备份日志写到/home/oracle/incr.log中
周日和周三凌晨1:00执行0级全库备份，周一、二、四、五、六凌晨1:30执行增量备份
