rsync can also do this:

rsync -av -e ssh directory/ user@example.com:/path/to/directory/

or

rsync -av -e ssh directory user@example.com:/path/to/


Or, you could use your incantation, but minus the ssh if you don't
need to pay for crypto:


# Target
nc -l -p <port> | tar xj

# Source
tar cj directory | nc <remote_host> <port>


Godwin, I am correct in thinking that 'f -' can be omitted, right? tar
reads from and writes to stdin / stdout AFAIK.
