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 databases keep getting larger and larger. And the larger the databases get, the harder it is to backup and restore them.  MyDumper has changed the way that we perform logical backups to enable you to restore tables or objects from large databases. Over the years it has evolved into a tool that we use at Percona to back up petabytes of data every day. It has several features, but the most important one, from my point of view, is how it speeds up the entire process of export and import.

Until the beginning of this year, the latest release was from 2018; yes, more than two years without any release. However, we started 2021 with release v0.10.1 in January, with all the merges up to that point and we committed ourselves to release every two months… and we delivered! …

And when that happens it will be the worst time to realize that your backup system hadn’t been working for months, or testing for the first time a cluster-wide recovery.

Forget about the backups, it is all about recovery!
