用asp的朋友，可以用下面的代码，实现mssql数据库的备份还原操作 <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>
<%
