MySQL Backup Strategy: Getting RPO and RTO Right

Backups Are About Recovery, Not Storage

The purpose of a backup is not to have a copy of your data. It is to be able to restore your database to a specific point in time within an acceptable window. Everything about your backup strategy should be designed backwards from your Recovery Point Objective (RPO) and Recovery Time Objective (RTO).

Physical vs Logical Backups

Percona XtraBackup provides hot physical backups that restore quickly but require the same or compatible MySQL version. mysqldump provides portable logical backups that are slower to restore but version-flexible. Most production environments need both.

The Backup You Never Tested

We have encountered multiple organizations that discovered their backups were incomplete or corrupt only when they needed them. Automated restore testing on a regular schedule is not optional. It is the only way to know your backups work.

Binary log archival rounds out the strategy by enabling point-in-time recovery between backup intervals. Together, these three components (physical, logical, binlog) provide the redundancy needed for serious data protection.
