I said this elsewhere but, in isolation there will always be failure scenarios where recovery is impossible. There are plenty of verification strategies to detect failures, and combined with redundancy, you can reduce the probability of application failure in the face of fsync failures or other similar failures. But you can never eliminate failures. If your storage gives up the ghost, it's game over. Distributed systems are the closest we've gotten to resilient, durable storage. Redundancy, external verification, quorum. Sometimes the distributed system lives in a single box on your desk.
