Again, there is no reason to think that this is not being worked on, and the posts in this thread confirm that Apple is fully aware of the issue now. As far as backups go, iCloud is not your only option. Back up your device to iTunes if you are concerned about losing any data. Import your photos to your computer (which you should always do anyway).
Yes, a segment of the Apple population has had issues with iCloud, but the majority of people who upgraded to iOS 9 do not have these issues. If they did, the number of views would be far greater than 100,000. Also, if you look at the dates on the thread, you will see that the activity has dropped off, so the large number of views could have been mostly accumulated at the beginning of this issue.
My device backs up to iCloud every time I plug it in to a power source. When I first upgraded to iOS 9, I had the same "Last Backup = Never" display that a lot of people were concerned about. For the first week after iOS 9 came out, I had the same issues that many people had with my automatic backups not working. However, it is clear that Apple did something because by the second week, the normal backup routine was back in place for me.
Clearly, there still are folks out there that are still experiencing issues, and the solutions that some of them have had to resort to are workarounds. Just because a update to the iOS has not come out yet is no reason to believe that that is any indication of Apple's intents concerning this issue.
Why not call them back to see if there is any additional help that they can provide now? A lot of things can progress and change in a month....
