"Save as New" and "Save as Copy" removed from article manager after 3.3.4 Upgrade
From Joomla! Documentation
After upgrading from Joomla v3.3.3 to v3.3.4 The "Save as Copy" and "Save as New" buttons are no longer available when editing an article. I used a backup to revert back to v3.3.3 and all is well.
