用Asp备份与恢复SQL Server 数据库


一个用asp备份与恢复SQL Server数据库的例子代码,希望对一些朋友有用。(注意:数据库使用中可能无法恢复)

复制代码 代码如下:

<HTML>
<HEAD>
<TITLE>SQL Server 数据库的备份与恢复</TITLE>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
</HEAD>
<BODY>
<form method="post" name=myform>
选择操作:<INPUT TYPE="radio" NAME="act" id="act_backup" value="backup"><label for=act_backup>备份</label> 

<INPUT TYPE="radio" NAME="act" id="act_restore" value="restore"><label for=act_restore>恢复</label>

<br>数据库名:<INPUT TYPE="text" NAME="databasename" value="<%=request("databasename")%>">

<br>文件路径:<INPUT TYPE="text" NAME="bak_file" value="c:\$1.bak">(备份或恢复的文件路径)<br>

<input type="submit" value="确定">

</form>
