# Nightly: pg_dump the paperless DB + mirror the media PVC into the scoped
|
||
|
|
# `paperless` MinIO bucket (see minio-provision-paperless-job.yaml). This is a
|
||
|
|
# BACKUP target, not live storage - paperless-ngx has no native S3 backend, it
|
||
|
|
# only ever reads/writes the local media PVC directly.
|
||
|
|
#
|
||
|
|
# Pinned to talos-cp-3, same as deployment.yaml: media is a ReadWriteOnce
|
||
|
|
# Longhorn volume with a single replica physically on that node's disk -
|
||
|
|
# mounting it read-only here from a different node would conflict with the
|
||
|
|
# live webserver's attachment.
