With RSync, I see
--delete-during deletes destination files during transfer.
What does "during" mean? Does "during" really mean during the overall transfer of files, but after each individual file?
But isn't "after each individual file" what
--delete-delay does? ..wait until transfer of each individual file is complete but before the entire set of file transfers is complete? Or does delete-delay mean after transfer of ALL files is complete? ..but that can't be because that's what
Summary: please help me clarify what people/docs mean when they say "after transfer" for each of the above 3 options. Is that after transferring THE file -- each individual file -- or does that mean after transferring ALL files?
