PROD: object storage moves to UpCloud Managed Object Storage (existing drops bucket) instead of single-node in-cluster MinIO — durable, UpCloud-replicated, no PVC to back up. - Remove forte-drop-minio StatefulSet entirely. - Add forte-drop-pg-backup CronJob: nightly pg_dump -> gzip -> upload to s3://drops/_pgbackups/ (collision-proof prefix), 30-day retention. Reuses forte-drop-secrets S3 creds (app user has s3:* on drops). - PVC prune/delete protection on the postgres volumeClaimTemplate.

# Nightly logical backup of the forte-drop Postgres → UpCloud Managed Object Storage.
|
|
# Dumps to s3://drops/_pgbackups/ (the `_` prefix is collision-proof: app slugs match
|
|
# /^[a-z0-9][a-z0-9-]{0,62}$/ and can never start with `_`). Retains 30 days.
|
|
#
|
|
# Pod shape: initContainer pg_dump → shared emptyDir → mc upload + retention prune.
|
|
# Both images pinned. S3 creds reuse forte-drop-secrets (the app's UpCloud user has
|
|
# s3:* on the drops bucket). PG creds from forte-drop-pg-creds.
