mysql实现自动远程备份一办法

?

一、实现本地自动备份数据库很简单:
1.以root身份登陆
2.计划任务(每天的3:30自动执行 /usr/bin/mysqlbackup)
crontab
0 3:30 * * * /usr/bin/mysqlbackup
3.写一个自动备份数据库脚本
vi /usr/bin/mysqlbackup
#!/bin/bash
mv /home/.../db_bak5.tgz /home/.../db_bak6.tgz
mv /home/.../db_bak4.tgz /home/.../db_bak5.tgz
mv /home/.../db_bak3.tgz /home/.../db_bak4.tgz
mv /home/.../db_bak2.tgz /home/.../db_bak3.tgz
mv /home/.../db_bak1.tgz /home/.../db_bak2.tgz
rm -rf /home/.../db_bak.txt
/usr/bin/mysqldump -uroot -ppassword dbname
> /home/.../db_bak.txt
cd /home/.../
tar czvf db_bak1.tgz db_bak.txt
二、这样每天的3:30就会在本地目录/home/.../下生成相应的数据库备份,开始由于/home/.../目录下缺少数据系统会提示错误,这是正常的
三、至于远程备份可以配合使用ftp或scp命令实现,方法很简单,查一下相关命令的使用,然后再改动一下mysqlbackup脚本就可以了


在win2003下MySQL数据库每天自动备份

终于让服务器每天早上备份一次 MySQL 数据库并自动打包,同时删除 5 天前的备份文件. 分享如下.

1. 环境: windows server 2003 + Apache 2.0 + PHP5 + MySQL 4.0.26 .

2. 假设 PHP 安装目录为 D:/php ,MySQL 安装目录为 D:/mysql.

3. 在 D:/php 下建立目录 WinRAR, 把你 winrar 安装目录下的 WinRAR.exe 和 RARReg.KEY 复制到 D:/php/WinRAR .

4. D:/php 下建立文件 mysql_backup.php:

/*/////////////////////////
#FileName: mysql_backup.php
#Author: faisun
#Website: http://www.softpure.com
////////////////////////*/
//保存目录,路径要用反斜杠.您需要手动建立它.
$store_folder = 'D:\databse_backup';
//用户名和密码
//该帐号须有操作[所有]的数据库及FILE的权限
//否则有些数据库不能备份.
$db_username = "root";
$db_password = "";
$time=time();
$nowdir = "$store_folder\\".date("Ymd",$time)."";
if(file_exists("$nowdir.rar")) die("File exists.\n");
@mkdir($nowdir);
mysql_connect("localhost","$db_username","$db_password");
$query=mysql_list_dbs();
while($result=mysql_fetch_array($query)){
system (dirname(__FILE__).'\..\mysql\bin\mysqldump --opt '."$result[Database]
-u{$db_username} ".($db_password?"-p{$db_password}":"")." >
$nowdir\\$result[Database].sql");
echo "dumping database `$result[Database]`...\n";
}
echo "\nWinrar loading...\n";
system( dirname(__FILE__)."\\WinRAR\\WinRAR.exe a -ep1 -r -o+ -m5 -df \"$nowdir.rar\"
"$nowdir\" " );
//删除 5 天前的文件
@unlink("$store_folder\\".date("Ymd",$time-86400*5).".rar");
echo "\nOK!\n";
>

5. D:/php 下建立文件 mysql_backup.bat,内容只有一句:

php.exe mysql_backup.php

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,可以把时间定在了早上 8 点整.

mysql的自动备份------这篇来自动网

time=`date +%G%I%d%H%M` #年月日时分

db=products
echo "#产品库\r\n" >/sqlbak/${db}_$time.sql #备份文件名为[库名_年月日时分.sql]
mysqldump --add-drop-table -c --allow-keywords --force --password=1234567890 --user=root $db >>/sqlbak/${db}_$time.sql


db=news #另一个库
echo "#新闻库\r\n" >/sqlbak/${db}_$time.sql
mysqldump --add-drop-table -c --allow-keywords --force --password=1234567890 --user=root $db |bzip2 -9 >/sqlbak/${db}_$time.sql.bz2


#--add-drop-table是添加一个删出命令。
#-c是完整插入,每行插入都包括字段名
#--force是出错也继续
#--allow-keywords是对于保留字做字段名时对字段名加反引号。
