Slightly less efficient but much more secure: run rsync over
ssh. 

rsync -a -e ssh /source/path/ user at remotehost:/destination/path

Or use a helper script like this:


----
if [ -n "${SSH_PORT}" ]; then
   args="$args -p $SSH_PORT"
fi

if [ -n "${SSH_USER}" ]; then
   args="$args -l $SSH_USER"
fi

if [ -n "${SSH_IDENTITY}" ]; then
   args="$args -i $SSH_IDENTITY
fi

if [ -n "${SSH_ARGS}" ]; then
   args="$args $SSH_ARGS"
fi

exec ssh $args "$@"
----

and set some variables, then call

rsync -a -e scriptname /source/path/ remotehost:/destination/path

rsnapshot is a good keyword.
