Are rsync operations atomic at file level?

Question

I\'m trying to figure out how if rsyncing files is atomic. I couldn\'t find any confirmation about it. Due to rsync being able to send only deltas, I was under the impressio

Answer 1

Rsync creates a new temporary file which will contain blocks from the local (receiving) copy and whatever blocks it requires from the sending copy. When done the temporary file is moved into place replacing the original.
