iPad mini won't allow a back up. The 'back up' button won't bold to allow a back up. I've tried everything I can think of.

Howdy DIRMNA,

It is not clear from your post whether you are trying to back up your iPad using iTunes on your computer or using iCloud. I will address both possibilities.

Use the steps in this article to make the backup - How to back up your devices using iCloud or iTunes.

If you are using iCloud and have problems making the backup, looks for solutions in this article - Get help backing up your device in iCloud.

This article will help if you can't make your backup using iTunes - If you can't make an iTunes backup of your iPhone, iPad, or iPod touch.

Thanks for using Apple Support Communities.

Best to you.
