I am searching for a way to provide nearly realtime sync between two windows servers (2012 R2) over the internet (no VPN available). Changes on the files will be on both of the servers. FTP seems to slow for that (detecting file system changes).
The problem is that changed files should be detected within max 1 minute and then should sync it.
Do you know a alternative to dropbox which supports a installation on a server and is running as a service?
Thanks in advance!
