1.       在dos命令行下运行数据库全备份批处理脚本full_backup.bat

因为mysqldump是mysql自带的exe程序，执行mysqldump时务必到mysqlbin 目录下运行脚本或双击full_backup.bat（在bat中要cd到mysql的bin目录下），其中full_backup.bat里面的mysqldump导出路径，指定导出服务器IP,数据库名称，字符集，用户名，密码需要根据具体情况修改

2.       全备份批处理脚本full_bakcup.bat如下：

@echo off

echo ======================

echo backup discuz databae

@REM 取出当前时间

for /f "tokens=1-3 delims=- " %%a in ('date/t') do (

set yy=%%a

set mm=%%b

set dd=%%c

)

for /f "tokens=1-3 delims=: " %%d in ('time/t') do (

set hh=%%d

set mi=%%e

)

@REM 设置mysqldump导出路径，指定导出服务器IP,数据库名称，字符集，用户名，密码等

set backupdir=E:\MySQL备份\mysql_backup

SET host=172.16.4.41

SET database1=discuz

SET character=--default-character-set

SET charactername=gb2312

SET mysqlpassword=discuz

SET mysqluser=discuz

SET logdir=E:\MySQL备份\mysql_backup

SET filename1=%database1%%yy%%mm%%dd%%hh%%mi%%ss%.sql

SET start=%date% - %time%: Database Backup of %database% Started

@REM Start Logging

ECHO %start%

ECHO %start% >> %logdir%\mysqlbackup.log

@REM dump database. This is all one line

mysqldump -h%host% -u %mysqluser% -p%mysqlpassword% %character%=%charactername% %database1% > %backupdir%\%filename1%

if not exist %backupdir%\%filename1% goto FAIL_DUMP

@REM All is well

GOTO SUCCESS

:FAIL_DUMP

SET message=%date% - %time%: Database Dump of %database1% Failed

GOTO END

:FAIL_MOVE

SET message=%date% - %time%: Backup Move of %database% Failed

GOTO END

:SUCCESS

SET message=%date% - %time%: Backup of %database% Completed Succesfully

GOTO END

:END

ECHO %message%

ECHO %message% >> %logdir%\mysqlbackup.log

ECHO ===============================================================================

ECHO

3.      加入WINDOWS执行计划执行每日备份

在“控制面板”=》“执行计划”=》“添加执行计划”下添加执行计划，我选择每日执行
