改进的ASP备份SQL Server数据库，网上原理的不是很好，需要的朋友可以参考下。复制代码代码如下:
<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>
<%
