If you chose ALL of the options when you did your sqz backup, these items should have been included.I do not see any place where it includes or does NOT include these items (separately listing task and sticky notes) in a backup. Have you tried printing a task summary list or a Sticky Notes List? And, if you still have your old data, you may want to do these lists from that. Perhaps someone else has a better suggestion. That's all I can think of at this moment. Best of luck!
