How would that work? If it didn't encrypt your active storage, then the backups wouldn't be encrypted either, right? Or would it somehow interfere with the backups, making you think the backup's OK when it actually is just garbage and then encrypt your active drive when no more usable backups exist? I guess that's one reason why if you don't try restoring from you backups it's as good as not having any...
