Dear All,

So we've had some major disk corruption on our hosted engine (hardware to 
blame), and we have taken backups. However, the hosted-engine VM will no longer 
boot at all, database is thoroughly corrupted, and we need to rebuild the 
thing. Just a sanity check on the best route:

Preamble:
VMs are still running fine - only hosted engine affected
VMs are distributed across our entire 3 node cluster
All 3 nodes are registered as hosted engine candidates

1. Do another hosted-engine --deploy on one of the existing hosts, and then 
restore the backup into that
2. Build a new host, deploy the hosted-engine, then restore a backup on a fresh 
node

Regards,
Callum
