Re: CYGWIN
I remember looking at Microsoft's NFS client several years ago as a way to shuttle files from Windows servers to Linux backup targets. I soon realized I'd rather shoot myself in the nuts than try to get it working. If memory serves, it was heavily reliant on Active Directory, which we didn't have at the time as we were a Novell shop. And I don't recall ever finding a way to get it to use "local" (non-AD) accounts.
Cygwin saved the day for me. I ended up using Rsync to copy the files, and didn't have to worry about mounting or mapping the Linux drives. To this day, that's still how I get the backup files from my Windows boxes to the Linux boxes. It has proven to be very, very robust over the 7 or 8 years I've been using it.
