Not so. For small file there is no advantage as any change may change the
whole file. Its for large files where only a  few blocks change that the
delta algorithms saves transfer time. And that's exactly where eCryptfs
ould help.

You don't like file level encryption but that is exactly what you have been
asking about. You cant move out of Windows but still want a scalable,
stable solution. Its all a contradiction of terms..
