shell监控自动备份是否成功(判断文件是否存在)

　　作者:邓聪聪

　　在自动打包生成备份sql文件后,对运行情况做一个监控！  命令前加time，查看命令执行完成所用时间！

FILE_DIR=/root/
DATE=$(date +%F)
FILE_NAME="cacti_bak.$DATE.tar.gz"
FILE=${FILE_DIR}${FILE_NAME}
erro=/root/mysql_bak.erro
ok=/root/mysql_bak.ok

tar -cvzf $FILE /root/cacti.sql


if [ ! -f "$FILE" ];
then
        echo "####### $DATE #########"> $erro
        echo "MySQL back up $DATE hava not created!" >>  $erro
        echo "MySQL back up failed" >> $erro
        echo  | mutt -s "测试" m18001131583@163.com  < $erro
else
        echo "MySQL back up $FILE have exist!" >$ok
        echo "MySQL back up successful!" >> $ok
        ls -lh $FILE|awk '{print $5,$9}' >> $ok
        echo  | mutt -s "测试" m18001131583@163.com  < $ok
fi

判断文件是否存在

#Crontab time 
# variables
FILE_DIR=/data/mysql_bak/   #备份存放路径
DATE=`date +%Y_%m_%d`      #获取当前系统时间
FILE_NAME="mysqldata_bak_$DATE.tar.gz" #最终保存的数据库备份文件名
FILE=${FILE_DIR}${FILE_NAME}

#echo "$FILE"

# 判断当天备份文件是否生成
if [ ! -f "$FILE" ];
then
      echo "####### $DATE #########">> /data/mysql_bak/mysql_bak.err
      echo "MySQL back up $DATE hava not created!" >>    /data/mysql_bak/mysql_bak.err
else
      echo "MySQL back up $FILE have exist!"
      echo "MySQL back up successful!"
fi
