asp在线备份sql server数据库：
1、备份sqlserver
复制代码 代码如下:
<%
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sqlserver
复制代码 代码如下:
<%
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
%>

ACCESS原理一样
复制代码 代码如下:
<%
'*****************************************
function CopyTo(ByVal cFile,ByVal toFile)
cFile=Server.MapPath(cFile) ‘所要备份的文件
toFile=Server.MapPath(toFile) ‘备份文件
Dim cFso,cf
set cFso=Server.CreateObject("Scripting.FileSystemObject")
cFso.fileexists(cFile)
cFso.Copyfile cFile,toFile
end function
