Cygwin sshd and rsync are okay for interactive use. There is a shell
script (ssh-host-config) provided with the Cygwin openssh package for
setting up sshd as a service.
Unfortunately, Cygwin rsync is notorious for working for a while, and
then hanging in the middle of a transfer. I've seen this for years, and
I saw it on up-to-date installs less than a week ago. So for automated
backups, you need to detect this failure mode and deal with it. The
only way I found to get rsync working again was to reboot.
You might find more encouraging answers on the Cygwin mailing list:

Currently, Windows Backup and Restore is the most reliable solution I've
found for automated backups. Either it works, or it doesn't (the last
Windows Vista box I maintain has broken Volume Shadow Copy, which breaks
Backup and Restore).
