asp 在线备份与恢复sqlserver数据库的代码

<% 
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 
 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 
 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
