That way if it failed 90% of the way through, I wouldn't have to resend all the data, just that last 10%. The way I managed to do this, was to:
split --bytes=10m file.iso file_part
What happens now is, you have a bunch of 10MB files called
So, just rsync all those files to the destination:
rsync -e ssh -a --progress file_part* firstname.lastname@example.org:
When that completes, login to the remote host and put them back together:
cat file_part* > orig_file.iso
Done and done.
