When I was still on dialup, I resumed downloaded of an iso with ncftp over a period of 5 nights (about 40 hrs total). Newer versions ask by default what to do if the destination file exists (overwrite, resume or cancel) From 'man ncftp':

auto-resume
NcFTP 3 now prompts the user by default when you try to download a file that already exists locally, or upload a file that already exists remotely. Older versions of the program automatically guessed whether to overwrite the existing file or attempt to resume where it left off, but sometimes the program would guess wrong. If you would prefer that the program always guess which action to take, set this variable to yes, otherwise, leave it set to no and the program will prompt you for which action to take.

Continuous upload 

The ncftpput program does not try to “resume” uploads by default. If you do want to resume an upload, use the “-z” flag.
