Rsync

rsync -a --stats /src/ /dst/

-a = -r (recursive), -l, -p (permissions), -t (times), -g, -o, -D

other usefull options:

-n = trial run
-h = human readable output
--progress (shows progression)
-i = itemised change list
-v = verbose
-vv = extra verbose
-u = update: only overwrite files with older mtimes

To use

--exclude-from=filename
filename has to be in the same directory as where the command is run and needs  the following lines

-------
- dir1/
- dir2/
----

which will exclude processing of /src/dir1/ and /src/dir2/

troubleshoot this with 
-vv

To rsync to a remote machine:

rsync -a /src/dir/ -e ssh userid@destination.ip.or.server.name:/directory/
