The Operator does logical backups, querying Percona XtraDB Cluster for the database data and writing the retrieved data to the backup storage. The backups are done using the Percona XtraBackup tool.

The Operator allows doing backups in two ways:

  • On-demand backups can be done manually at any moment and are configured in the deploy/backup/backup.yaml .
