I see a couple of posts but not a direct answer, I am needing to restart my Ipad and want to back up to the cloud. All is selected except mail and when I select it it wants me to open an icloud mail account. I use gmail and I am wondering what it will do to my mail. Will it just back everything up and then put it back the way it was when I restore? Do I ever really need to use the icloud mail acct for anything in the future. Just want to be clear about what I'm doing before I hit the go button.
