AWS RDS Backups: What’s the True Cost?

You have your database instance deployed with AWS and you are using AWS RDS for MySQL. All work smoothly in terms of satisfying queries for your application and delivering reliable uptime and performance. Now you need to take care of your backup strategy. Business is defined to have this retention policy:

  • 7 daily full backups
  • 4 weekly backups
  • 12 monthly backups

Plus the ability to do point-in-time recovery (PITR) for the last 24 hours since the last full backup was taken.

The cloud vendor solution

This is a piece of cake. The daily backups: just set the backup retention period to six days. Done. This also has the plus that PITR is already covered since RDS uploads the transaction logs to S3 every five minutes and stores them in the parquet format, making it smaller than the regular text file. All amazing, right?

Now, the weekly and …

MySQL Server on Microsoft Azure 3rd part (backup and recovery)

Azure Database for MySQLIntroduction

This blog is the third chapter related to deploying a MySQL infrastructure on the Azure cloud. In addition to performance, we should indeed also consider backup and restore capabilities. The objective of this blog is to present the main backup and restore possibilities offered by Azure through a simple example and show a second backup/restore possibility using MySQL Shell dump utilities.

Backup window and mechanism

Flexible Azure for MySQL generates by default a 7 days server backup retention period. This retention period can be extended up to 35 days or shorten to 1 day. In addition we can decide if you want to have a Geo Redundant backup storage. By default the backups are locally redundant.

It’s important to understand that Azure makes backup of the …

MySQL Server on Microsoft Azure 2nd part (Performance tests)

Azure Database for MySQLIntroduction

This second blog follows the first blog about deploying MySQL Server on Microsoft Azure. In the first blog, we saw how easy it is to deploy a MySQL server in minutes on the Azure cloud and we connected on it through the MySQL Shell client.


This second blog is more focused on the performance of MySQL in the Azure Cloud. Although I didn’t do any tuning of MySQL parameters, we will see the influence of MySQL Server localization on the latency as well as changes in parameters such as CPU, memory or IOPS on performances using the SysBench tool.

SysBench stress test

Of course there are many tools available to do stress tests. On my side, I decided to use SysBench simply because I know this wonderful free tool and because it is widely deployed. Rather than …

Exploring MySQL on Kubernetes with Minkube

In this blog post, I will show how to install the MySQL-compatible Percona XtraDB Cluster (PXC) Operator on Minikube as well as perform some basic actions.   I am by no means a Kubernetes expert and this blog post is the result of my explorations preparing for a local MySQL Meetup, so if you have some comments or suggestions on how to do things better, please comment away!

For my experiments, I used Minikube version 1.26 with the docker driver in the most basic installation on Ubuntu 22.04 LTS, though it should work with other combinations, too. You also can find the official “Running Percona XtraDB Cluster on Minikube” documentation …
