Actions disappearing

Well, once again, all my actions have disappeared after an upgrade. Yes, I have all mine saved but I remember my horror and distress the first time this happened and expect there are a few folk out there who have experienced the same.  For people who don't have backups (because they never imagined Photoshop would just lose the lot), is there somewhere in their CC account where they are saved? If not, isn't it about time there was?!
