Why not use rsync/Cygwin for windows? Deltacopy has a package that will push both together.
There are other options you can do depending on if/what you have budget for and what problem you are actually trying to solve (ie: do you just want your backups off the server? Why not have MySQL backup directly to the remote server? do you need multiple copies of the backup? Is using an actual backup application feasible? etc)
edit:
If you are looking at Cobian backup, why are you mentioning rsync? Those would do the same things.
If all you want to do is copy data from one location to another and there isn't that much data, write a batch/powershell/vbscript to do the file copy using UNC paths and run it as a scheduled task. Just make sure the user account that it is set to run under has proper permissions to the local directory and the remote share. If you want logging, you can do that with robocopy or redirect the output of your file copy to a text file in your script. If you want to use a 3rd party tool like Cobian, you can run it as a service and still use UNC paths to the appropriate servers.
