I have a question before making the data downloader in Nas.

Hi, everyone. I have a question before the production. I want to make a downloader of the data in Synology Nas and download what users have on the Jenas server, but in this case, is there no need for Nas to run a separate program?

Even if I make a chat program, I program the server side to play a role and run it We make client programs.

I wonder if NAS needs to produce such a server program separately.
