Need help making a backup routine using Windows software

[idea]

Here is the scenario: Several Windows PCs that need to have files backed up to a linux fileserver. I need a simple and free method. Windows is such a goddamn pain. My linux machines are all backed up with a single line of code using rdiff-backup. Why can't it be this easy?

What I have tried:
- Sharing out the Windows machines, and pulling files using rdiff-backup. This was a pain in the ass but I could get it to work if I spent enough time on it, plus I don't like sharing out the Windows machines so I gave up.
- Robocopy. I could probably live with this, if I could get it to work. Keeps telling me access is denied to change attributes? Oh well
- SyncBackSE, bloatware that costs money... meh
- Cygwin + rdiff-backup for windows. Couldn't get it to work, plus the last release is from 2006 so I stopped trying.

Any other ideas?

ntbackup running as a scheduled task, backup to a share on the linux server.

Google has a huge listing of linux backup software that runs with and without clients on windows machines.

They are all crap, nothing is as good as rdiff-backup.

I've been using Cobian for years, you can set it up to run as a service if you want. I have it autostart with Windows and set up scheduled backups to the server i have in the basement
