I lost a ton of photos stored in an app called 'PhotoManagerPro'. These photos have restored perfectly fine via iCloud for years. Until iOS9 hit town...
Camera Roll photos restored in reverse order, SMS were lost, app data was lost, a good 50% of apps crashed as soon as they were opened and really the whole iCloud backup was trashed. I had to delete and reinstall a ton of apps, and all of my data apart from Camera Roll was lost. Way to go Apple, iCloud backups/restores are actually one of the big positives that keep me tied to iPhones and my 13GB backup has basically become garbage.
