The Scenario is we got 1 SBS 2011 Server at a main office with around 30 workstations then 3 external offices with approx 8 or 9 workstations connecting to it all via a LAN to LAN VPN Tunnel. Internet Connection at all sites averages around 40MB down and just under 10MB Upload.
The External Offices PC's are domain joined to the SBS and have worked absolutely fine however each user has their own my documents data and they have been increasing in staff.
We had been getting them to work on their my documents folders/files locally then installed syncback on each PC to backup to the SBS at the main site once or twice a day (as when I tried to get them working live on their my docs across the VPN tunnel in the past the users complained about the speed being too slow and it was unworkable for them)
We want to get a better more reliable solution that doesn't require so much baby sitting (i.e. checking each PC's individual syncback log each day to make sure it worked etc, and to be honest it's always causing an error here or there due to some users having long file names etc)
I was going to suggest a Standard Windows Server at each external site to allow DFS to automatically do the data replication of their my documents?
I haven't ever had to configure/setup DFS before but I know in theory this is what it's supposed to do and is possibly their best solution?
Any feedback about potential ideas would be greatly appreciated.
Thanks in Advance.
