How so? Dropbox is zero config install for linux.

I never said zero config, I said easy to configure. Firefox has plenty of configuration nobs, but it's easy to configure it.

No because that's very complicated. I've done it in the past, and just the fact I have to manage a VPS to do so is more than what I want to do.

I've used rsync as well, it's again, too much scripting, meaning to much margin for errors.

Apple Time machine for linux is what I want, with remote capabilities.
