exponentially delayed replication down the replica chain...

  Why increase the interval at all? Why not just equally, or at most linearly increasing, delayed replication?

    With replication at 1 minute intervals and ten replicas, you can step back at most 10 minutes. Same with replicas at 1, 2, 4, 8, etc minutes, ten replicas let you step back up to 17 hours. Much more time to detect and correct a catastrophic error.
