Secure Sync between remote computers

I've been trying to find a tool that will Sync between two remote computers securely and also run as a service so I don't have to stay logged in.

Windows Live sync seems to do the job although I've read it can't be run as a "service" reliably because it will occasio开发者_运维百科nally log out of the service [http://www.dscoduc.com/post/2009/06/24/Dont-run-Live-Sync-as-a-Service.aspx]

Is there any alternatives out there or has anyone got the Live sync running as a service reliably?

Thanks Chris
