I currently run a small company network where one of the requirements is that we upload documents we create to a web server were they can be securely viewed by our clients. The current system we use creates the documents and then when they are finalised they are published to the web server via FTP. The program creates a WinSCP script and then uploads them to a given directory and updates a database table. The system works but needs some manual intervention if a document is amended after transfer and just feels a little clunky.
Internal servers are currently Server 2008 R2, the web server is hosted externally and also runs Server 2008 R2 with IIS. We could if we wanted run the web server inhouse from within our DMZ, but using a hosting company simplifies the DR scenarios for the web setup.
The web server needs to remain Microsoft Server, but what other methods are there for securely transferring documents to a web server that I could look in to? The ideal method would be a way to sync specific internal folders with the web server, maybe in a similar fashion to DFSR (the web server isn't joined to the domain) if it's available?
