Within a cross operating system network containing different versions of Windows Clients (Win98, NT, Windows 7) and a Linux file server I would like to sync folders.
There are two limitations:
1) Each client should sync to a specific folder on the server but the clients should not sync between each other due to disk space limitations.
Server -+- SyncFolder for Client A <---> Folder_X on Client A | +- SyncFolder for Client B <---> Folder_Y on Client B
In the example above Client A and Client B do not sync.
2) NO internet connection is available therefore Dropbox cannot be used but private Cloud setups such as Owncloud.
What solutions are out there?
Edit: A perfect solution would instantly sync just like dropbox or similar tools and not require user interaction.
