实现 win2003 下 mysql 数据库每天自动备份

<"root";  
$db_password = "";  

$time=time();  

$nowdir = "$store_folder\\".date("Ymd",$time)."";  
if(file_exists("$nowdir.rar")) die("File exists.\r\n");  
@mkdir($nowdir);  

mysql_connect("localhost","$db_username","$db_password");  
$query=mysql_list_dbs();  


$command = '';  
while($result=mysql_fetch_array($query)){  
  $command .= dirname(__FILE__).'\..\mysql\bin\mysqldump --opt '."$result[Database] -u{$db_username} ".($db_password"-p{$db_password}":"")." > $nowdir\\$result[Database].sql \r\n";  
  $command .= "echo dumping database `$result[Database]`... \r\n";  
}  
  $command .= "echo Winrar loading...\r\n";  

$command .= dirname(__FILE__)."\\WinRAR\\WinRAR.exe a -ep1 -r -o+ -m5 -df \"$nowdir.rar\" \"$nowdir\" \r\n";  

$command .= "echo OK!\r\n";  

$command .= "del mysqldumping_temp.bat\r\n";  

$fp = fopen('mysqldumping_temp.bat','w');  
fwrite($fp,$command);  
fclose($fp);  


//删除 5 天前的文件  
@unlink("$store_folder\\".date("Ymd",$time-86400*5).".rar");  
"htmlcode">

<"htmlcode">

echo off  
php.exe mysql_backup.php  
if exist mysqldumping_temp.bat call mysqldumping_temp.bat 




6. 双击该 bat 文件运行,如果能备份了,OK,下一步添加任务计划.  

7. 把 D:/php/mysql_backup 添加到任务计划,时间选每天. 根据服务器的监测结果,每天早上 5-8 时为流量低峰期. 由于 5-7 时有些数据库的清理工作,我把时间定在了早上 8 点整.
