Backup Software PowerFolder

I haven't played with it yet, but there is an open source backup application called "PowerFolder" that looks interesting. It is SoureForge's Project of the Month this month. To get that distinction, an application has to be pretty high quality, so it's certainly worth checking out. I'm dropping it here so I can find it later. It could be a little confusing to search for since: takes you to: PowerFolder is workflow server and development studio. As opposed to: which is where the backup software is.
