since trying to synchronize folders from my server failed, I'm trying a different approach, tgz'ing directories and then get'ting the tgz. Though this fails with a timeout:
Session started. Active session:  root@root_mine /root Host is not communicating for more than 15 seconds. Still waiting... Warning: Aborting this operation will close connection! (A)bort: Abort Terminated by user. Session 'root@root_mine' closed.
option batch continue option confirm off option transfer binary open root@root_mine cd /root call tar -czf rootdir.tgz * get rootdir.tgz call rm -f rootdir.tgz
