If it doesn’t ignore existing by default, what’s the difference between that and plain old copy?
Rsync checks the files and only issues the copy if the file size/modified dates are different by default. Ignore existing will not overwrite a changed file afaik.
If the file is large it only sends the changed blocks (e.g. you have a 100gb database and only a dozen 4mb blocks have been modified it won't send the full 100gb across the network)
