For example, suppose we are using a T.F.T.P server to back up a router config file or a much larger file such as an IOS. Since the transmission of the config file or the IOS is being sent via UDP, what happens if an error occurs in transmission? Does the entire IOS not get copied from the router to the T.F.T.P server? I don't quite understand why UDP is used in this case involving file transfers. I understand why UDP is used for things such as VoIP, but it seems to me that reliable transport would be better suited to file transfer (such as backing up files to a T.F.T.P server). Can anyone clarify please? Thank you.
