How do I restore an app backup?

[iMore Question]

When apple updated to IOS 8, my checkbook app crashed. I have a backup, but cannot figure out how to restore it. I just need to get the info from the back up. I cannot get the developer to return my emails. Please help!!!

The backup/restore process is an all or nothing proposition. You cannot selectively restore apps or data from a backup.
