Not Ubuntu related

But it is open source related.

I built a backup utility for our datacenter based on rsync. It used rsync in the background but gives our non unix technicians the ability to backup shares, folders with rsync on windows without needing us unix gurus to setup the backups.

It has all the rsync features, plus scheduler and can build the UI options into a script so you can have a nice icon to just double click on to do the backups whenever and/or throw them into your own schedules uses the scheduler for windows.

here's a video of it I posted on youtube.
