用最简单的步骤备份sql数据库的文件到本地:

response.Charset = "utf-8"

Session.Codepage = 65001

Response.Buffer=true

Response.Clear

'根据你的情况修改用户名和密码

constr="Provider=SQLOLEDB.1;Persist Security Info=True;User ID=endiva;Password=endiva;Data Source=211.160.78.6"

set conn=server.createobject("adodb.connection")

conn.open constr

bkfname=server.mappath(Format_Time(Now(),5)&"database.bak")

sqlstr="backup database fang to disk='"+bkfname+"' with init"

conn.execute sqlstr

conn.close

response.Write "database [fang] is backup success!
"

response.Write "click download"

如果想直接备份并下载，可以加上下边的这部分，就会备份后自动保存。但是弹出的文件是.asp的文件，修改下就OK。

'set fn=server.createobject("adodb.stream")

'fn.mode=3 '读写

'fn.type=1 '数据类型为：adTypeBinary

'fn.open

'fn.LoadFromFile bkfname '将bkfname指定的文件装入对像中

'Response.ContentType="application/octet-stream"

'Response.BinaryWrite fn.read

'fn.close
