CNPG's barmanObjectStore.serverName defaults to the externalClusters[]
entry's own .name field ('home-backup', an arbitrary label I chose) -
NOT the actual source Postgres cluster's name. Home's backup: block
(on the real pg-authentik/pg-n8n/pg-nextcloud Clusters) defaults
serverName to its own metadata.name instead. Without an explicit
override these two disagree, so recovery searches the object store
under the wrong server-name prefix and finds nothing - 'no target
backup found', confirmed live even after the ScheduledBackup fix
produced real, completed base backups.

# CNPG replica cluster continuously replaying WAL from home's pg-n8n
|
|
# (apps/n8n/manifests/cnpg-cluster.yaml) via VPS MinIO's
|
|
# cnpg-backups/pg-n8n bucket path. Same pattern as
|
|
# infrastructure/vps-standby/authentik/manifests/cnpg-cluster.yaml - see
|
|
# that file's comments for the full rationale (replica-cluster mode vs.
|
|
# custom restore scripting, read-only until manual promotion).

|
|
# vps-minio-secret is a plain Secret copied here manually (kubectl, not
|
|
# git), same as the authentik one:
|
|
# kubectl -n n8n create secret generic vps-minio-secret \
|
|
# --from-literal=accesskey=<vps minio root user> \
|
|
# --from-literal=secretkey=<vps minio root password>
