1、备份
<%
SQL="backup database 数据库名 to disk='"&Server.MapPath("backup")&"\"&"backuptext.dat"&"'"
set cnn=Server.createobject("adodb.connection")
cnn.open "driver={SQL Server};Server=服务器名;uid=sa;pwd="
cnn.execute SQL
on error resume next
if err<>0 then
response.write "错误："&err.Descripting
else
response.write "数据备份成功！"
end if
%>

2、恢复
<%
SQL="Restore database 数据库名 from disk='"&Server.MapPath("backup")&"\"&"backuptext.dat"&"'"
set cnn=Server.createobject("adodb.connection")
cnn.open "driver={SQL Server};Server=服务器名;uid=sa;pwd="
cnn.execute SQL
on error resume next
if err<>0 then
response.write "错误："&err.Descripting
else
response.write "数据恢复成功！"
end if
%>

注：以上语句是把数据备份到磁盘的backup目录下，文件名为backuptext.dat。
