Full Replication

I want to replicate a windows server to another windows server like a mirror through a VPN connection.

I need a full replicate programs, data, active directory, etc...

I don't need to have a fail over, so I don't need if the first server have a problem, the another server become the main server, I only need to have a full mirror server in another place for security reasons.

Any suggestion about how can I do it?

Regards

Is it a DOMAIN topology, or simple WORKGROUP?

You should run ntbackup.exe and select system state which will back you up your Active Directroy and all the files you need. On the other side, you simply restore the files, let AD syncronize and you're done.

Sorry, a little modification: Sorry for my english, what I wrote can be misunderstandable.
So: you should select system state - this will back up registry settings, Active Directory and other system important things.
And, you should also select the files you need from your HDD drives.

I need a continue real time replication, it's a domain server with apps and files

With ntbackup you don't have to take your server offline.

But is not a real time replication

The solution may depend on what you are prepared to spend.
A 'no additional cost' may be as follows.
You do not mention the OS, but I assume Windows Server 2003 R2
If there is little change in the apps. installed then you could do the following :
Have the backup server a backup domain controller.
Use DFS to replicate data from the main server to the backup server.
Server 2003 R2 is very good at this, because if you modify a 200MB file , only the modified pages are replicated and not the entire file.

Perhaps I may not have been clear.
What is the configuration that you have at present ?
That is our starting point.

I have a windows server 2003 with apps and files, I have a fiber channel VPN, and we want to do a hot full replicate in real time

The best practices sollution would be:
- setup a new server 2003 R2, and DCPROMO it to existing domain to become the secondary domain controller
- then, you need to go service-by-service, DHCP, DNS, RRAS...etc, to assure everything is in sync and working properly on both servers
- then configure DFS on both, and let sharing use only DFS namespace
Excluding few details, you wil gain a fully functional always-in-sync copy of working server, and also have full redundancy.

Other aspects of having off-line server ready and to be it always-in-sync, is hard to establish with no additional investments. The second server will have at least different name and IP, so it cannot be instantly ready to use.

You *can* use some backup utility, like Acronis ECHO, which is capable of doing VSS-aware on-line copies of working files to backup location, but I doubt very much it would be still usable after few months, when some changes in AD will be made.

So my point of view is to have AD replicated using built-in mechanisms for replication. Also, 2nd server needs to be in Domain Controller state, so it has to be DC even before you need it - you won't DCPROMO it afterwards.

DFS is excellent mechanism to keep file replicas in sync over many servers, so it's recommended to be used.

You might have a bit heavier job to do in the beginning to set it up properly, but you will end with full redundancy, much better than off-line server copy.
