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)
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>
