Well, I've been testing with rsync+ssh from Cygwin on a KVM virtual
machine with Windows Server 2012. So far everything has worked smoothly:

As you can see, the transfer was over than 3 GB and it were not hung. I
did several tests and all were without problems.

I wonder if in the mentioned episodes of hangs you remember whether the
transferred volume was higher or lower than in this case (or it hung
randomly).

As a side note, the larger file (disk01.img) took more than 40 minutes
to be transferred. So the rsync was running quite some time without
hanging. While it does not have to do with the topic of this thread, in
rsync progress data we can see that the average transfer rate was 10
Mbps. I guess it will have to do with that I'm going through a wireless
network. In this testing the Debian computer is a notebook connected to
the wireless router and the KVM Windows is on the wired network. May it
be so large the decrease in transfer speed? The wireless router is
TPLink WDR3600 with OpenWRT.


Kind regards,
Daniel
