通过编写dos命令脚本生成批处理命令文件，然后在主机服务器上添加计划任务来实现。
备份方法：
在任何磁盘上根目录下新建bak文件夹，在bak文件夹中新建week0.dmp，将下面的dos命令复制到新建txt中，，把x:\修改为实际的路径，然后将*.txt命令为zlautoexp.bat批处理文件。

然后在控制面板的计划任务添加zlautoexp的计划任务执行时间，根据用户的需求来调整备份时间，使用administrator用户必须给该用户添加密码。
或者在dos命令提示符下输入以下命令可以实现自动备份:
at2:00 /every:m,t,w,th,f,s,su x:\bak\zlautoexp.bat
时间        每周七天        自动备份文件路径
同理在zlautoexp中添加主机字符串，同样可以在工作站上实现异地自动逻辑备份。
添加自动备份任务：保证服务里task scheduler打开，而且在命令提示符中输入的自动备份命令完全是在后台自动执行，前台不会出现任何提示。
