...I just wanted to check, whether there is water in the pool... :) I minute ago I found this: https://unix.stackexchange.com/questions/203018/interrupting-rsync-with-ctrl-c-should-i-use-partial-or-append which rises a question about how to resume an interrypted rsync-session. It looks like the final answer was not found... Any additional ideas about that? Cheers! Meino
