The backup process (when done through Enterprise Manager as an example) is just a set of SQL commands run against the database.  I used SQL Profiler to "watch" what enterprise manager is doing when you run a backup - and you could easily do the same.

It appears as though something like the following will create the backup file:

<cfquery name="back_it_up" datasource="#session.mydsn#">
  BACKUP DATABASE [your_DB_name_here] TO  DISK = N'C:\Program Files\Microsoft SQL Server\MSSQL\BACKUP\whateveryouwantyourfiletobe.bak' WITH  INIT ,  NOUNLOAD ,  NAME = N'My backup',  NOSKIP ,  STATS = 10,  NOFORMAT
</cfquery>

Assuming you can then do some CFFile actions on the file that is created above (file permissions etc) - then you should be able to write the script to download it.

Let me know if you want me to expand on this...

This is a permissions issue with the username you are using to connect.  Nothing wrong with the code as such - so I would go into the security are of enterprise manager and take a look at what the user is setup as.

There are a number of flags that can be set for the users access/privilages to the db, from memory I cant remember the exact name, but there is one that does say "backup" something in it.

Try turning that on for the user you are working with, and see what happens.

Hello, i have the same question. But in my case the SQL server is not the same machine the CF running. It is remote. I'm trying this

<cfquery name="back_it_up" datasource="#request.datasource#">
BACKUP DATABASE bgtaweb6 TO DISK = '\\10.2.9.89\dbbackup\bgtaweb6.bak' WITH  INIT ,  NOUNLOAD ,  NAME = 'bgtaweb6',  NOSKIP ,  STATS = 10,  NOFORMAT
</cfquery>

But get this error
[Microsoft][SQLServer 2000 Driver for JDBC][SQLServer]Cannot open backup device '\\10.2.9.89\dbbackup\bgtaweb6.bak'. Device error or device off-line. See the SQL Server error log for more details.

Could u pls help?
