If the Internet connection is lost, will the FTP continue to work or will it fail?

Question

FTP

Good morning. The question is not standard. You need to upload 48GB of video to the cloud storage. This is one video 4 hours long filmed in high quality. The question is this. If, for example, I uploaded 15GB, and the Internet connection disappears for a couple of minutes (it happens sometimes) when resuming, will the process continue or fail? This is one file
Thanks in advance
