Overview

There are times when I need to restore a slave from a backup of a master or another slave, but too many times I have taken the typical approach of taking the backup on the source server and then copying it to the target server.  This takes a great deal of time, especially as your database grows in size.

These steps are going to detail how to use Netcat (nc) and Percona Xtrabackup (innobackupexec) to stream the backup from the source server to the target server, saving a great deal of time by copying the data only once to the desired location.  While the data is streaming to the target server, it’s being compressed and then uncompressed on the fly, reducing the amount of traffic going across the network by around 85% to 90% (typical backup compression ratios of MySQL Innodb I have witnessed are in this range).  I will also provide a simple script to complete these steps to give you a start at creating your …

Ok, so now we’re got our InnoDB Cluster a-clustering, MySQL Router a-routing, now we need some disaster to be a-disaster-recovering…

A foreword first.

If you’re looking to use Enterprise Backup to recover a single node and restore that node back into an existing InnoDB Cluster, LeFred takes you through that one nicely here.

Preparing for backup

On our single primary server, the one that allows write, which was ic2/10.0.0.12 in my case:

mysql -uroot -poracle << EOF 
SET sql_log_bin = OFF; 
 create user 'backup'@'%' identified by 'oracle';
 grant all on *.* to 'backup'@'%';
SET sql_log_bin = ON; 
EOF

Let’s create something to backup (if you haven’t already done so of course):

mysqlsh --uri …

Want to setup InnoDB Cluster and be prepared for a Disaster Recovery scenario? Get ready:

Here’s a way to set up InnoDB Cluster using the 3 environments, on Oracle Linux 7.2, 5.7.19 MySQL Commercial Server, MySQL Shell 8.0.3 DMR, MySQL Router. As this is the first blog post for a complete disaster recovery scenario of InnoDB Cluster, we’ll also be installing MySQL Enterprise Backup.

If you’re new to InnoDB Cluster then I’d highly recommend looking at the following to understand how it works and what Group Replication, Shell & Router are.:
