Why am I getting an error message when trying to update my iPad to IOS 8.1.2?

I am trying to update my ipad to IOS 8.1.2

I keep getting a message that my ipad cannot be updated, you must restore it to factory settings. I don't want to do this, as I didn't back it up before trying to update.

Try backing up before restoring.
