Hey Guys

I am familiar with other NAS builds, Synology, Drobo, etc. First time I am trying to deploy/manage two Buffalo TeraStations..

I did a very quick search, and I think my questions is simple enough -

I have 1 Remote NAS in Minnesota, that is the companies FTP / Backup and I am going to deploy one in Los Angeles.

The Los Angeles group wants everything to mirrored off of the Minnesota NAS, but they wish to be able to edit/add/remove files and have these changes reflect on the Minnesota NAS.

From what I can see, Replication will get the files from Minnesota to Los Angeles, but any changes made on the Los Angeles side will not be synced/reflected on the Minnesota side, so (correct me if I am wrong) Replication is not my answer.

I was going to establish a VPN between both locations and then use a 3rd party software such as (Good Sync/Beyond Compare or even a RoboCopy) to accomplish the two-way synchronization.

My question to you guys is if any of you have any recommendations or experience that is relevant to this type of project and its scope, I would appreciate any information that is shared.

Model of both NAS units is - Buffalo TeraStation TS3400D

We are successfully replicating in both directions between (2) TS3400D's. I'll try to explain how, but I am not the person who figured it all out. Hopefully I'll have all the important details for you. Remember, your mileage may vary.

*** Note: if one folder is empty and the other has files and replication is turned on first on empty side, files may be deleted at other end ***
*** Suggest starting with empty folders for testing ***

1) both devices have the same folder names for replication
2) established VPN between the 2 sites (our VPN between sites is any/any for all protocols)
3) make sure you can ping the IP of the other remote TeraStation from each location
***  Perform the following at each end ***
4) in Backup; Backup - click "List of LinkStations and TeraStations" - (<sarcasm> intuitive, right? </sarcasm>)
5) click refresh to detect TeraStations - our remote device shows up
6) add the remote TeraStation to Off-subnet Devices (ours was added by host name)
7) close List of LinkStations and TeraStations; Close Backup List
8) in Backup; Replication; Add -Select your local Source Folder and Target Folder

This is what worked for us. It initially was set up with both devices on the same network for testing, but I was informed that it works this way for adding the remote site. The devices are set up with AD authentication and local a DNS server, so the host name name resolution works at both ends.

This is correct. VPN is the most secure way to do this, and you just use the built in replication function.
