在Linux风行的今天，与Windows机器相互共享文件已经是非常普遍的应用了，关于samba的设置的文档也相当的多，本站也有不少了。不过在使用它的高级功能方面还是比较欠缺的，这类文档是非常稀有的，而且只有英文版的，为了方便国内的Linux用户，我将这些文档整理一下，翻译过来，并结合自己一些经验，为大家提供一些帮助。
注：这篇文章并不是一篇关于如何配置samba的基础文档，而是需要阅读者有一定的Linux使用经验，熟悉脚本语言，并且对samba有一定的使用经验。主要是针对于一些企业的Linux网管，或比较有经验的Linux爱好者。
这篇文章也其说是文章，不如说是一个技巧提示，但是我个人觉得它意义非常大，特别是对于大中型企业的用户来讲，它可能非常重要。
它主要描述了如果在Linux下使用samba来为使用Windows系统的机器作备份，并且描述了如何跨子网共享samba。
1、将Windows机器备分到一台Linux主机上
Adam Neat(adamneat@ipax.com.au)，向我们提供了以下一段代码，它描述了如何使用smbclient软件包将windows机器备份到Linux主机上。Adam说它可以用来备份windows 3.x和NT机器到一台Linux的磁带机上。
另一段代码，是Dan Tager (dtager@marsala.com),提供的，Dan的脚本是通过rsh来备份Unix机器，尽管它可以修改成ssh以便使其更简单些。
在下面这个脚本中，字符串“agnea1”是作备份工作的Linux主机的一个用户名。
#!/bin/bash
clear
echo Initialising ...
checkdate=`date | awk '{print $1}'`
if [ -f "~agnea1/backup-dir/backup-data" ]; then
echo "ERROR: No config file for today!"
echo "FATAL!"
exit 1
fi
if [ -d "~agnea1/backup-dir/temp" ]; then
echo "ERROR: No tempoary directory found!"
echo
echo "Attempting to create"
cd ~agnea1
cd backup-dir
mkdir temp
echo "Directory Made - temp"
fi
if [ "$1" = "" ]; then
echo "ERROR: enter in a machine name (ie: cdwriter)"
exit 1
fi
if [ "$2" = "" ]; then
echo "ERROR: enter in a SMB (Lan Manager) Resource (ie: work)"
exit 1
fi
if [ "$3" = "" ]; then
echo "ERROR: enter in an IP address for $1 (ie:
130.xxx.xxx.52)" exit 1
fi

以上两个文件都是针对于具体的机器而设计的，如果您准备对自己的机器也进行备份，那么请您安照您自己的机器的具体情况来修改这两个文件的一个，就可以使用了。
2、跨子网使用samba
许多大型企业有不同的子网，但是如何将另一个子网的内容被其它子网共享，是一个非常关键的问题，许多samba的用户在这里遇到许多麻烦，如果这点被解决了，
