I have a client that has sbs2011 at their main site then server 2008 R2 at a remote site. The 2 sites are connected with a site to site VPN. Currently I am looking for a way for them to have one folder for both offices for their documents / data. The way it is currently setup is each office has their data on their own server. This is done for performance reasons but they would prefer to have one place to get to all their data. The problem I see with this is if we put all the data on one server the other site will have performance issues pulling the data over the VPN as opposed to over their gigabit LAN. I am looking for a way to have one location that all the data is stored in and syncs to both servers. Not sure what the best way to accomplish this would be? I looked into Onedrive but the sharing options seem limited. I looked into Bit Torrent Sync and DFS but just wanted to get some additional input from you guys to see your thoughts / suggestions. Thanks in advance.
