Q: Help with iCloud Backup?

Yes and yes.

Sorry, I put all this in my initial post--not sure why it didn't show up.  When I backup now, I get a message that the backup cannot be completed.  Last Backup:  Unknown

yes, confirmed that I was actually connected to wifi and tried again twice; both times "the last backup could not be completed".

Thank you ckuan.  I will follow these links and revert back.
