Any thoughts on the right way to approach it? No, that's a tough one, especially with a back up the size you're doing. Everytime you do a restore that's just confirmation that a particular backup was/was not sound. Wouldn't it be neat if the back up program had functionality that allowed you to restore a random sample of your files ( and maybe then compare these to the originals ) and give you a likelihood that your entire backup is sound? A sort of sampling quality control process.
