You should use rsync over ssh
rsync -P -e ssh remoteuser@remotehost:/remote/path /local/path
The key option is -P, which is the same as --partial --progress
By default, rsync will delete any partially transferred file if the transfer is interrupted. In some circumstances it is more desirable to keep partially transferred files. Using the --partial option tells rsync to keep the partial file which should make a subsequent transfer of the rest of the file much faster.
Other options, such -a (for archive mode), and -z (to enable compression) can also be used.
