I've been testing cygwin 1.7 on Server 2008 with rsync. First, the install went flawlessly. I'm just using a standard path of E:\cygwin...no fstab issues.
Compiling rsync worked without a hitch. The rsync version is 3.02 with the preallocate patch applied. The patch takes advantage of the posix_fallocate feature. There have been two major improvements I've seen with the 1.7 build on Server 2008: - The long file name errors that used to always be a problem are no longer there which is great news. - The overall I/O performance is much higher. I don't have hard statistics but have been watching throughput on the SAN connected to the server. With old cygwin and Server 2003 I was lucky to get sustained throughput of 40M-50M. Now I'm seeing throughput of 100M-120M all the time with bursts much higher. It is possible the performance gain is helped by Server 2008 as I have not attempted to run the old cygwin on 2008 for a true comparison. I think a lot of it is also in the cygwin version since I'm sending the email to that list. :) Sorry I don't have any more hard data as we continue testing 1.7. Thought I'd at least let you know some of the nice things I'm seeing.
