In addition to PKI encrypted communications for login sessions there is the scp command which enables you to copy entire file hierarchies from one machine to others with a single command and the use of shell meta characters.

There is also the ability to create encrypted “tunnels” for data stream end points with ssh and so much more.

Rsync is insanely powerful and efficient. Love, love love it. Makes my life easier when I need to replicate data from one host to another. Since it uses ssh, it's secure, and can also compress to reduce transmission times, among other things.
