I'll see what I can do. Since it is transferring quite a lot of data
before timing it out, I set up tcpdump to limit itself to 96 bytes.
Otherwise this would fill up the disk quite quickly.

~# tcpdump -v -s96 -i tun2 port rsync and host 10.21.32.5 -w
pcap/client.pcap

Yes, absolutely. Right now for instance it's transferring these files:

pool     444   400/401     2016768 Program Files (x86)/Corel/CorelDRAW
Graphics Suite X5/Setup/CGS15/Draw.msi

and a quick check shows that these files are already present on the
target host:

~# ls -l /mounts/raid/backuppc/pc/client/92/fC/fProgram\ Files\
\(x86\)/fCorel/

The backup process is always starting with /cygdrive/c so at least some
of these files should be "same".

BR,
David
