[原创]MYSQL周期备份shell脚本 [原创]MYSQL周期备份shell脚本

这个脚本是实现阿里云mysql数据库全量周期备份的shell脚本，实现备份数据按一周星期几分开存放。一下是脚本内容：

#!/bin/bash

echo `date`
echo "backup begin!!!"

DATE1=`date +%Y%m%d%H%M%S`
DATE2=`date +%w`
BACKUPDIR="/data/backup/backupdir/"
BACKUPPATH="/data/backup"
BACKUPNAME="/data/backup/backup_${DATE1}.tar.gz"

NAME=`mysql -hrdsabcdefghijklmnopqrstuvwxyz.mysql.rds.aliyuncs.com -uusername -ppassword <show databases;
exit
EOF`
for dbname in $NAME; do
if [ "$dbname" = "Database" ]; then
echo "The 'Database' is not a database."
else
mysqldump -hrdsabcdefghijklmnopqrstuvwxyz.mysql.rds.aliyuncs.com -uusername -ppassword $dbname > $BACKUPDIR${dbname}.sql

fi
done

cd $BACKUPDIR
tar zcf $BACKUPNAME *

echo `date`
echo "backup over!!!"

case $DATE2 in

1) mv $BACKUPNAME $BACKUPPATH/1; ;
2) mv $BACKUPNAME $BACKUPPATH/2; ;
3) mv $BACKUPNAME $BACKUPPATH/3; ;
4) mv $BACKUPNAME $BACKUPPATH/4; ;
5) mv $BACKUPNAME $BACKUPPATH/5; ;
6) mv $BACKUPNAME $BACKUPPATH/6; ;
0) mv $BACKUPNAME $BACKUPPATH/7; ;
*) echo $DATE2; ;

esac
cd $BACKUPDIR
rm -rf *

echo `date`
echo "Over!!!"
