I did mount with -o sync right now to try if the problem still exists then. It seems, although transfer is very slow (120 kb/s), it works like this at least. So far I have transfered several files, together over 800 MB, and so far notice still the memory problem (RAM dropping to 4MB), but the system no longer hangs. The Memory problem still isn't very nice - forcing swapspace on my system, since it seems not enough memory is freed fast enough :/ Well it might be usable as a backupdevice like this at least.
