If you need to resume an scp transfer from local to remote, try with rsync:
rsync --partial --progress --rsh=ssh local_file user@host:remote_file
Short version, as pointed out by @aurelijus-rozenas:
rsync -P -e ssh local_file user@host:remote_file
In general the order of args for rsync is
rsync [options] SRC DEST
This is all you need.
rsync -e ssh file host:/directory/.
