--partial not working?

Hi Kevin, 

I haven't specified --whole-file. After entering an rsync command the terminal always reads "delta-transmission disabled for local transfer or --whole-file" but I assume that is just a standard phrase that always appears. 

So, if I am running partial (-P) and not using --whole-file or disabling the delta-transmission, why would an incomplete file be deleted and the transfer start anew after an interruption?

Partial means don't delete the incomplete file.  The file is being transferred because it doesn't match.  But rsync does delta-transfers so it won't actually transfer the parts that match.  It will just verify that they do match.

Unless of course --whole-file.
