One way to move files between servers is by using the
scp command. Secure copy command utilizes ssh to transfer data.
The simples example for copying a file from local to remote server is
scp /localdir/localfile firstname.lastname@example.org:/remotedir/remotefile
Similarily, to copy file from a remote to local server would be
scp email@example.com:/remotedir/remotefile /localdir/localfile
