通过shell脚本实现对oracle RMAN备份集压缩并异地备份

1、背景说明

2、备份方式重新规划

3、备份脚本分享

#!/bin/bash
# tar oraclebackup file

# check RMAN is run?
#我做RMAN备份的时候都会创建一个RMAN日志，所以此日志就可以判断我的RMAN是否执行了
filename="/mnt/rman/log/RmanBackup_`date +%y%m%d`.log"
comparedata="Recovery Manager complete."

if [ -e $filename ];then
echo "`date` RMAN is run" &>> /OPS/tarlog
else
echo "`date` RMAN is not run,please check" &>> /OPS/tarlog
exit 1
fi

# check RMAN is OK?
#通过判断我的日志最后结果，判断RMAN备份是否成功，如果没有成功，我也没必要备份了
data=`tail -1 $filename`
if [ "$data" == "$comparedata" ];then
echo "`date` Rman backup sucess" &>> /OPS/tarlog
else
echo "`date` Rman backup fail" &>> /OPS/tarlog
exit 2
fi

# tar backupfile and move to backupserver
#将当天的备份集压缩备份出来并move至对应nfs提供的文件夹，我300GB的备份压缩后只要30个G，压缩比还是很惊人的
/usr/bin/find /mnt/rman -name 'oradb1*' > /OPS/tarlist
for i in `/bin/cat /OPS/tarlist`;do
echo "`date` tar $i start" &>> /OPS/tarlog
tar -zcvf $i.tar.gz $i &>> /OPS/tarlog
done

if [ $? -eq 0 ];then
echo "`date` tar end success" &>> /OPS/tarlog
mv /mnt/rman/*.tar.gz /oraclebackup
if [ $? -eq 0 ];then
echo "`date` move to oraclebackup end success" &>> /OPS/tarlog
else
echo "`date` move to oraclebackup fail" &>> /OPS/tarlog
fi

else
echo "`date` tar fail" &>> /OPS/tarlog
fi
