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.

Architecting reliable backup and recovery strategy


I have been managing multiple databases, mostly in Microsoft SQL Server and MySQL server, both on on-premise and cloud. We have faced a lot of challenging issues such as records deleted from a user table, backup file is corrupted, backup file is not compatible, backup files got deleted, backup storage is full and backup is running for long time, etc. When you are facing this issues for the first time, it is surprising to see new kind of issues every day and if you are not good in documentation, repetitive issues will keep occurring and we keep fixing rather than suctioning. If you are facing same challenges, then you need to focus on your backup and recovery strategy.
