Folder Sync Software

[Redhatcc]

Does anyone know of a good folder sync software that will sync up to or more than 20gb of data online?

I have these folders at work, home, and on several computers i need sync'ed together (most of it is up to date but i add a file every now and then)

Not messed with any windows rsync ports, yet...

i did se groove until i found out that there was a 2gb limit ect.

but i also have to sync these across the internet instead of at a lan or vpn...
