I need some (MySQL) backup!

"If you have a hammer, all you see is nails." also known as the Law of the Instrument describes the cognitive bias that involves over-reliance on a familiar tool. To protect MySQL data, a DBA must have a toolbox full of the proper utensils. To know only one approach is not enough.

In this talk, we will cover the following topics:

- Why your backup strategy is probably wrong?

- Backups: Cold, hot... and warm?

- The right answer is not always the logical one.

- Replication is not the solution.

- Cold backups: rsync, snapshots...

- Warm backup using rsync.

- The logical song:

   - Mysqldump.

   - Mydumper.

   - Mysqlpump.

   - MySQL shell.

- Getting physical:

   - Percona XtraBackup: my swiss army knife.

   - MySQL Enterprise Backup.

- Point-in-time recovery.

- Don't try this at prod: Test your backups.
