As noted already, yes you are. Indeed, if you specify zfs recv -F, you only need to destroy @1 at the source. When you later send -R, snapshots destroyed at the source will also be destroyed at the receiver. That's not always what you want, so be careful, but if it is what you want it's useful. -- Dan.
