* **logical_backup_docker_image**
Docker image for the pods of the cron job. Must implement backup logic and correctly handle pod and job restarts. The default image runs `pg_dumpall` (on a replica if possible) and uploads compressed results to an S3 bucket under the key `/spilo/pg_cluster_name/cluster_k8s_uuid/logical_backups` Default: "registry.opensource.zalan.do/acid/logical-backup"
An image for pods of the logical backup job. The [example image](../../docker/logical-backup/Dockerfile) runs `pg_dumpall` on a replica if possible and uploads compressed results to an S3 bucket under the key `/spilo/pg_cluster_name/cluster_k8s_uuid/logical_backups`. The default image is the same image built with the Zalando-internal CI pipeline. Default: "registry.opensource.zalan.do/acid/logical-backup"
* **logical_backup_s3_bucket**
S3 bucket to store backup results. The bucket has to be present and accessible by Postgres pods. Default: empty.
