InnoDB Cluster: Recovering an instance with MySQL Enterprise Backup.

Ok, so if you’re reading this, then I can guess you’ve got a MySQL InnoDB Cluster in an awkard shape, i.e. you need to restore a backup and add the instance back into the cluster, so we have all our instances again.

As it might be logical to think “ah, but I’ve only lost 1 instance, a read-only instance, so all I have to do is backup & restore the other read-only instance and I’m home free. Well I want to make it a little harder. So in this scenario, assume that we’ve lost both the READ-ONLY instances, so I need to backup my primary READ-WRITE instance.

I’ve got a 8.0.16 instance, on Oracle Linux 7.4. We’ll be looking at 2 hosts, ic1 & ic3.

I’ll assume you’ve got access to Oracle …
