Yes - it takes a bit longer to do an rsync full because it reads all the 
data on the target, but it doesn't take much more bandwidth. And a full 
becomes the base comparison for the next run where incrementals will 
normally transfer all changes from the last full unless you have set up 
incremental 'levels'.
