The retention is automatically configured based on the settings in "helix-on-prem-deployment-manager/utilities/disaster-recovery/dr-configs/disaster-recovery.config".

For example, if DR_MAX_BACKUP_TO_RETAIN=1, and this represents one day, then when the next backup completes, the earlier backup will be cleared.

For PostgreSQL data cleanup, ILM (Index Lifecycle Management) policies are also set on the bucket. To review what retention is set, please follow the below steps:

Example:

1. Log in to the MinIO pod:

kubectl exec -it minio-0 -n itomwmk bash

Run:

mc --config-dir /bitnami/minio/data/.mc --quiet --insecure alias set localminio http://minio:9000 admin bmcAdm1n

Example:

minio-0:/opt/bitnami/minio-client/bin$ mc --config-dir /bitnami/minio/data/.mc --quiet --insecure alias set localminio http://minio:9000 admin bmcAdm1n
Added `localminio` successfully.

2. List buckets:

mc --config-dir /bitnami/minio/data/.mc ls localminio

minio-0:/opt/bitnami/minio-client/bin$ mc --config-dir /bitnami/minio/data/.mc ls localminio

[2025-03-02 15:33:41 UTC]    0B helixdr-backup/

3. Run the below command with bucket name (e.g., helixdr-backup):

minio-0:/opt/bitnami/minio-client/bin$ mc --config-dir /bitnami/minio/data/.mc ilm rule list localminio/helixdr-backup
