[rabbitmq-discuss] Outage, brokers refuse to start back up

[James Carr]

Okay, so I backed up our mnesia dir and wiped it clean on both boxes.
Brokers started fine. I then copied the DCD and DCL files back over
and my users, exchanges, and queues were back.

Is there a recommended way to protect against such an outage?

Thanks,
James
