Last time I had to do this I ended up using the ntbackup util that comes
with windows and getting it to save to a file on a samba share. This at
least meant that it dealt with things like NTFS ACLs/permissions and
other such windows oddities. Cygwin, while great in that you can at
least have a decent command line on windows, is very slow. I'd hope that
you could get better, depending on the connection between the servers.
