1、导入测试数据库数据
建库
show databases;
CREATE DATBASE easthome;
建表
CREATE TABLE tj(name varchar(8),tel int(8));
CREATE TABLE sex(name varchar(8),sex int(1));
插入信息
INSERT INTO easthome.tj(name,tel) VALUES('LIYAN',88888888);
INSERT INTO easthome.tj(name,tel) VALUES('zy',77777777);
insert into easthome.sex(name,sex) values('zy',1);
mysql> insert into easthome.sex(name,sex) values('LIYAN',0);
Query OK, 1 row affected (0.00 sec)
insert into easthome.sex(name,sex) values('yangchen',1);
insert into sex(name,sex) values('zhangyun',0);
mysql> show tables;
+--------------------+
| Tables_in_easthome |
+--------------------+
| sex |
| tj |
+--------------------+
2 rows in set (0.00 sec)
mysql> select * from sex;
+----------+------+
| name | sex |
+----------+------+
| zy | 1 |
| LIYAN | 0 |
| yangchen | 1 |
| zhangyun | 0 |
+----------+------+
4 rows in set (0.00 sec)
mysql> SELECT * FROM easthome.tj;
+-------+----------+
| name | tel |
+-------+----------+
| LIYAN | 88888888 |
| zy | 77777777 |
+-------+----------+
2 rows in set (0.00 sec)
2、开始备份
mysqldump备份成dump文件
==============
MySQL 安装位置：D:appmysql57
数据库名称为：easthome
MySQL root 密码：redhat
数据库备份目的地：D:db_backup
脚本：
rem *******************************Code Start*****************************
@echo off
set "Ymd=%date:~,4%%date:~5,2%%date:~8,2%"
D:appmysql57inmysqldump.exe -uroot -predhat --default-character-set=binary -f easthome > D:db_bakupeasthome_%Ymd%.dump
@echo on
rem *******************************Code End*****************************
将以上代码保存为backup_db.bat 调试时可以在结尾加上pause，查看是否正常执行
然后使用Windows的“计划任务”定时执行该脚本即可。（例如：每天凌晨5点执行back_db.bat）
说明：此方法可以不用关闭数据库，并且可以按每一天的时间来名称备份文件。
通过%date:~5,2%来组合得出当前日期，组合的效果为yyyymmdd,date命令得到的日期格式默认为yyyy-mm-dd(如果不是此格式可以通过pause命令来暂停命令行窗口看通过%date:~,20%得到的当前计算机日期格式)，所以通过%date:~5,2%即可得到日期中的第五个字符开始的两个字符，例如今天为2009-02-05,通过%date:~5,2%则可以得到02。（日期的字符串的下标是从0开始的）
3、导入到冷备库中 #在这里卡了半天，原来mysqldump只是导出工具，导入时必须要用mysql
在cmd中登录mysql
mysql -uroot -p
create database mytest
use mytest
source d:db_bakupeasthome_20160901.dump
show tables; #检查是否导入成功
效果如下：
mysql> source D:db_bakupeasthome_20160901.dump
