No. That's the obvious thing to do (two pass), but it's also the wrong thing to do, because if you delete first and then can't copy, you've lost data (especially with a move or rename).
But why wouldn't this work safely if the source drive has items that should no longer be on the destination drive. For example if you delete folders on the source drive and clone the drive the same folders will be deleted on the destination drive. Can't you have a option that allows deletes to proceed copies (freeing up space). Even if the rest of the cloning fails you were still going to delete the file on the destination drive anyway, yu haven't lost anything you were giong to loose anyway. You're just doing it first. It fact it might help you save data... if you forget to check the log you might assume the backup worked when it failed. It might have a small speed advatange as well by freeing up space so the other copies go faster. But most important it means th user doesn't have to worry about cloning failing if low on disk space or working wih large files.
