Problem restoring iPad backup

[milomak]

I updated the iPad (4 mini) to iOS 9.3.4

I then erased all content and settings

I setup the iPad again and choose to restore from iTunes

I select the backup I want to restore

iTunes tells me

The backup "BackupName" cannot be restored
to this iPad because the software on the iPad is too old.

To restore this iPad from this backup, you must first set up the iPad as
new and restore the software to the latest version

I believe I have done this from reading around on the web. What am I missing?

Have you checked to make sure it updated to 9.3.4?

Are you sure the backup wasn't made on iOS 10 beta?
