# CNPG backup ScheduledBackup coverage

**Parent / origin:** descoped out of `RAIL-HO-WP-0005` (Forgejo Production
Migration, finished 2026-07-14) T04/T09. The migration is complete; this is the
residual **DB-backup operational hardening**, not a migration blocker.

## Goal

Drive `make cnpg-backup-status` (railiance-apps) from **degraded → healthy**:
scheduled, unattended, encrypted, off-cluster backups with a passing restore
drill for all four production CNPG clusters — `apps-pg`, `gitea-db`,
`net-kingdom-pg`, `state-hub-db` (CoulombCore `databases` namespace).

## Current state (2026-07-22)

- T01 (CCR-2026-0004 offsite credentials) is **done**: catalog
  `railiance-backup-offsite-lane` is `resolvable: true` / `readiness: ready`;
  OpenBao path holds `NC_WEBDAV_TOKEN`, `NC_WEBDAV_URL`, `AGE_PRIVATE_KEY`;
  OIDC role `railiance-backup-workload-kv-read` grants `read` on the data path
  (verified 2026-07-22, capabilities-safe / key inventory only).
- `cnpg-backup-status` still reports degraded under the old barman
  `ScheduledBackup` definition; Option A logical-dump schedules are the target.
- Phase 1 evidence for `apps-pg`/`vergabe_db` exists (RAILIANCE-WP-0013); this
  workplan generalizes to all four clusters with unattended coverage.

## Task: Provision CCR-2026-0004 offsite credentials (operator)

```task
id: RAILIANCE-WP-0015-T01
status: done
priority: high
needs_human: false
state_hub_task_id: "3df45d8d-39e0-45db-9611-941f066c610a"
```

Operator provisions `NC_WEBDAV_TOKEN`, `NC_WEBDAV_URL`, `AGE_PRIVATE_KEY` per
`CCR-2026-0004` so the lane becomes resolvable. **Done when:**
`warden access railiance-backup-offsite-lane --fetch NC_WEBDAV_TOKEN` succeeds and
the CCR flips to `resolvable: true`.

**Closed 2026-07-22:** CCR `resolvable: true`, `readiness: ready`; OIDC login +
data-path `read` capability + field presence verified without printing values.
Note: OIDC token cannot `auth/token/create` (403 expected); verify with
`bao token capabilities` on the current token and/or key inventory, not child
token minting.

## Task: Create offsite backup Secret in databases namespace

```task
id: RAILIANCE-WP-0015-T02
status: progress
priority: high
state_hub_task_id: "7d9b2022-c533-4d49-9a91-fc34ae99aa9a"
```

Once T01 resolves, materialize the `databases` namespace Secret from the lane
(no plaintext in Git — sourced via OpenBao/operator path). **Done when:** the
Secret exists and `pg_dump`/WebDAV upload authenticates.

## Task: Wire scheduled backup for all four CNPG clusters

```task
id: RAILIANCE-WP-0015-T03
status: progress
priority: high
state_hub_task_id: "2b97e3ee-6284-4e5f-b56e-df57194cc7b8"
```

Implement the decided Option A lane as an unattended schedule for `apps-pg`,
`gitea-db`, `net-kingdom-pg`, `state-hub-db`: age-encrypted logical dump →
Nextcloud WebDAV, 14 daily + 4 weekly retention. Uncomment/parameterize
`manifests/cnpg-backup-readiness.yaml` (or CronJob equivalent). **Done when:**
each cluster has a running scheduled backup producing encrypted off-cluster
artifacts without manual intervention.

## Task: Reconcile cnpg-backup-status health definition with Option A

```task
id: RAILIANCE-WP-0015-T04
status: progress
priority: medium
state_hub_task_id: "151656cb-73ca-4d52-842e-22f14690f71c"
```

`cnpg-backup-status.sh` currently reports `degraded` whenever a CNPG-native
`ScheduledBackup` resource is absent, but the decided approach is logical-dump
CronJobs, not barman `ScheduledBackup`. Update the health check so a passing
Option-A schedule reports **healthy** (or adopt barman ObjectStore if chosen
instead). **Done when:** `make cnpg-backup-status` reflects the real, decided
posture.

## Task: Restore drill + RPO/RTO evidence, mark healthy

```task
id: RAILIANCE-WP-0015-T05
status: wait
priority: high
state_hub_task_id: "59f41267-94a9-45f0-a9d7-3c0cb16689ff"
```

Run an isolated-namespace restore drill from a scheduled artifact for at least
one cluster; record RPO 24h / RTO 4h evidence. **Done when:** `make
cnpg-backup-status` → **healthy** and restore evidence is recorded.
