I'd use ssh keys, check the man page on how to specify keys for use with 
rsync/ssh.

Careful with wildcards, they may be interpreted different than you expect.

I made this script, the script assumes that paths are the same on source 
and destination:

#!/bin/sh
# RSYNC_USER is set as an environment variable or defaults to $USER
RSYNC_USER=${RSYNC_USER:-$USER}

# Exit if RSYNC_HOST not defined, there is no good default value.
if [ -z $RSYNC_HOST ]; then
   echo "RSYNC_HOST undefined, no host to syncronize with.";
   exit;
fi

# RSYNC_PATH sets the path to be syncronized, defaults to $HOME
# would be neat to check if path is absolute or else assume relative
# to $HOME or set RSYNC_PATH as environment/command line variable
if [ -z $1 ]; then
   RSYNC_PATH=$HOME;
else
   RSYNC_PATH=$HOME/$1
fi
# Syncronize folders
echo "Syncing $RSYNC_PATH..."

# Exclude patterns may be stored in .rsync in the home directory or
# the sub directory being syncronized
if [ -f $RSYNC_PATH/.rsync ]; then
   rsync -Cptuvaz --rsh="ssh" --exclude-from=$RSYNC_PATH/.rsync \
     $RSYNC_PATH/ $RSYNC_USER\@$RSYNC_HOST:$RSYNC_PATH;
else
   rsync -Cptuvaz --rsh="ssh" \
     $RSYNC_PATH/ $RSYNC_USER\@$RSYNC_HOST:$RSYNC_PATH;
fi

exit;

You put your exclude list in a file, .rsync (see the man-page), what to 
exclude may depend on the directory you're rsyncing. If you're 
automating this as a cron-job, then you may not have the environment 
variables set.

I think that rsync defaults to ssh so the --rsh is really obsolete, but 
I like to make it explicit.

Cheers, Erik
