OOM Backup and Restore

On local minikube, the following configuration works:

bitnami.yaml

But trying to replicate the configuration to the actual cronjob on oom it's been unsuccessful.

cronjob.yaml

pv.yaml

The issue seems to be the mapping of paths from containers to hostPath.

The most common issue seems to be that backup container (mariadb-galera-backup-init) is unable to start the backup and create the folders, then the validation container (mariadb-backup-validate) fails as paths used are not created.
