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

There is a perl script that is supposed to add this functionality: http://www.opensource.apple.com/source/rsync/rsync-40/rsync/support/atomic-rsync

The problem is that I tried to test it and it doesn't work. Also there is something strage because from the URL it looks like being something related to rsync 4.0 and the current version of rsync is 2.6.9 !
