Further to my own email, try this one:

-- START --

#!/bin/sh

# List of directories to back up
dirlist="
/home/me/backupfiles"

# Root to back up to
backuproot="/tmp/backup"

# Check if backup root exists
if [ ! -d $backuproot ]
    then
    mkdir -p $backuproot
fi

# Loop through all directories in source list
for srcdir in $dirlist
  do
  # Check if source dir exists
  if [ -d $srcdir ]
      then
      # Create all appropriate destination directories
      for destdir in `find $srcdir -type d`
	do
	if [ ! -d $destdir ]
	    then
	    mkdir -p $backuproot$destdir
	fi
      done
      # Copy all newer than those already there
      # NB you may want to use -x here to stay on one filesystem
      cp -uva $srcdir $backuproot$srcdir
  else
      # Oops! Invalid search directory
      echo "$srcdir does not exists, or is not a directory"
  fi
done

-- END --

Just put your own source directories in the dirlist declaration at the top, 
and your own destination in the backuproot.
