MySQL InnoDB Cluster – Recovering and provisioning with MySQL Enterprise Backup

July 11, 2019

Like I stated in my previous article – MySQL InnoDB Cluster – Recovering and provisioning with mysqldump :
“As the administrator of a cluster, among others tasks, you should be able to restore failed nodes and to add (or remove) new nodes”.
Well, I still agree with myself 🙂
MySQL customers using a Commercial Edition have access to MySQL Enterprise Backup (MEB) which provide enterprise-grade physical backup and recovery for MySQL.
MEB delivers hot, online, non-blocking backups on multiple platforms including Linux, Windows, Mac & Solaris.

MySQL InnoDB Cluster – Recovering and provisioning with mysqldump

July 9, 2019

As the administrator of a cluster, among other tasks, you should be able to restore failed nodes and grow (or shrink) your cluster by adding (or removing) new nodes.
In MySQL, as a backup tool (and if your amount of data is not too big), you can use mysqldump a client utility that performs logical backups.
The results are SQL statements that reproduce the original schema objects and data.
For substantial amounts of data however, a physical backup solution such as MySQL Enterprise Backup is faster, particularly for the restore operation.
But this is the topic of my next blog post 🙂
