Hi, So in some ways, you would like to use rsync as a "diff/patch" tool. There are some similar questions out there (here<http://serverfault.com/questions/62364/get-rsync-to-generate-a-patch-file-instead-of-copying-across-files> or there <http://lists.samba.org/archive/rsync/2005-January/011439.html>), and the answers are quite similar too. Basically, two methods : I. Bash scripting (1. Do a dry run and export the files list, 2. Get only these files on your USB, 3. Push the new/updated files on the original system) II. Batch-mode (see this example<http://www.linuxmantra.com/2011/02/rsync-in-batch-mode.html> )
