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_backupvalue=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>
