Say, there is only one quorum node within each organisation (among many other quorum nodes which are spread out in other organisations) and that quorum node encountered some catastrophic incident where all the data (i.e., EVM state) is wiped out.
How can one restore the data? Or perhaps the question is how can one backup the evm state? What will be the backup and recovery strategy?
Does connecting the quorum node back to the network work? I tried removing the entire node data and tried to connect the quorum node back it did not work. I am using Raft consensus and the error returned: Was the raft log corrupted, truncated, or lost?
