There is also a linux subsystem for windows 10 which I have never used. Perhaps someone can say if that has rsync.

[ edit ] if that and cygwin are too heavy, you could request the samba team create a posix windows build of rsync. They had one long ago, but stopped supporting it. That would be a single binary. I suspect they will push back.

This is even heavier. It's a full blown Ubuntu install.

After a bit of Googling, it looks a company has complied and packged rsync for Windows at a cost of $19 per license @ https://www.itefix.net/cwrsync

I found a Github repo with an older (2017) version of cwRsync that may be from before it went behind a paywall @ https://github.com/billyc/cwrsync-installer

It does.
