My workaround for this bug assumes you tested for the destination file presence BEFORE doing the copy and removing/moving one away if found.  Otherwise you won’t know if you are looking at an older version of the file when testing after the copy.

In my code I’m making a versioned backup and loop over file names (file-1, file-2, ... file-n) until I find a name that is not in use and then attempt the copy.
