该博客展示了使用ASP实现SQL Server数据库备份与恢复的代码。通过表单让用户选择备份或恢复操作，输入数据库名和文件路径。代码根据用户选择执行相应操作，若备份或恢复成功会给出提示，若有错误也会显示错误信息。

<form method="post" name="myform" action="?action=backupdatabase"> 
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" id=submit1 name=submit1> 
</form>
