This is not specifically a cygwin solution, but I am using it with my
cygwin installation as well as interesting parts of my windows
installation.

Restic is a program that does backups right.

home page: https://restic.github.io/
documentation: https://restic.readthedocs.io/en/latest/
source: https://github.com/restic/restic

Read the home page. I think it meets its design goals very well.

HTH,
Doug
