These are just German Umlauts and in my opinion not connected to the "too many open files" errors.

Really? I thought these ones...
| 54 683224840 [main] rsync 1396 __set_errno: cygheap_fdget::cygheap_fdget(int, bool, bool):387 val 9
...were the ones you were looking for

It's very simple zsh script:

#! /bin/zsh -f
emulate -R zsh

setopt globdots

rsync -rt --links --delete --partial --progress \
      /cygdrive/$1/*                            \
      /cygdrive/$2/thorsten/backup/usb

CVS? I've never done this.
http://cygwin.com/faq/faq.programming.html#faq.programming.building-cygwin
seems quite a lot to do. Will this just build cygwin1.dll?

Never done this, too. This is all so c-ish, couldn't you port Cygwin to Python?? :-)
