We’ve currently got a Dell server running HyperV and two instances of Windows Server 2016. One instance is for active directory and file server, and the other is for Sage. We are getting rid of Sage and moving to a cloud based system, so are now questioning whether we would be better off swapping the server for a NAS. What I would ideally like is a NAS where I can have one at the office that would be mapped to the pc’s, then one at home that would sync CHANGED FILES only to the NAS at the office and visa versa. Is this possible and would it make sense rather than maintaining a full server? Also how would active directory work on something like a synology?
