I will be getting a new server to replace our Windows 2003 file server and the users from a remote site like to know if I can add a replicating server to their site.  Our main file server server is located in Texas and the remote site is located in Florida.  They currently access the file server through Cisco ASA VPN.  There are 5 users and they do Solidworks, so they usually do them locally and the files are large.  They then copy the file to the main file server and sometime that cause issue with the toolset that they use.

Basically, does anyone know a good way to do replication in real time between the two sites if I get identical server for each site?  Site A changes will get replicate to site B and vice versa?  Thanks and appreciate the helps.

Hi,

Seems that DFS replication is the function you are looking for. See:

However you may need to consider about:

1. DFS replication will be triggered by a "file save". If a file is saved in both of your file server, the one saved later win the replication priority. So it may cause conflict if the earlier version is actually needed. Though DFS will move the conflict version to a hidden folder instead of deleting it directly, you may still need to check if it is fine in your environment.

2. If the network speed is slow between your 2 sites, DFS replication may not be finished in time, which causes it useless as files are always updated before an replication is finished.

With a pretty fat pipe between sites it's trivial. As you do VPN and files are huge the only reliable way to move on would be utilizing asynchronous replication based on a CBT (changed block tracker). Using built-in tools you may try to use Hyper-V Replica (file server virtualized) or DFS. Both in "one way ticket" mode. No black magic here unfortunately :(
