However, if you don't want to do it online you could try creating a torrent? That will cause you to have to upload TBs of data and your ISP might not like that, so check your plan first.
When done you can send the infohash to whoever you want to send the data to them directly.

It's incredibly simple! You open any torrent software, select the "create torrent" option, select whatever file/folder you want to, add whatever metadata you want like torrent name and info, and save it.
You'll have to be running your computer online basically 24/7 but it should work.
