iCloud can do what you want, but there are things to look for on each service. I'll throw out a few random things to check, but I don't know enough to give real help at this point. In Settings > iCloud make sure each service you want is turned on for both devices. In the Notes app, see if you've got and Accounts button. It's possible you've separated your notes into more than one account, including a local one. If so you may have to manually copy and paste your notes to the iCloud account. Personally, for notes, I much prefer Evernote. I only use the Notes app to hole stuff temporarily while I copy, edit, paste stuff, (kind of like a clipboard for text) or am experimenting with the keyboard. Be sure to visit iCloud.com on a computer and make sure that your Contacts, Calendars, and Reminders (part of Calendar on iCloud) are syncing to the site. For backups, go to Settings > iCloud > Storage & Backups on both devices. Fiddle around, check out Manage Storage and the other info to see if you can figure out what the problem is. You should be able to see the backup info for both devices, but only change it for the one you are on. Thats all I can think of off the top of my head. Good Luck.
