# 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).

## Outcome (2026-07-22)

- Option A lane live: Secret `databases/cnpg-backup-offsite`, four CronJobs,
  status ConfigMap, multi-cluster workstation runner.
- `make cnpg-backup-status` → **ok** for all four clusters.
- Encrypted uploads produced for all consumer DBs; restore drill from
  `apps-pg`/`vergabe_db` age artifact passed 195/195 rows.
- Evidence: `docs/evidence/cnpg-option-a-backup-20260722.json`,
  `docs/evidence/apps-pg-restore-drill-20260722T155951Z.json`.

## 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.

## Task: Create offsite backup Secret in databases namespace

```task
id: RAILIANCE-WP-0015-T02
status: done
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.

**Closed 2026-07-22:** `make cnpg-backup-offsite-secret-apply` created
`databases/cnpg-backup-offsite` with `NC_WEBDAV_TOKEN`, `NC_WEBDAV_URL`,
`AGE_PUBLIC_KEY` (private key not in-cluster). Upload authenticated via
workstation runner using the same OpenBao lane.

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

```task
id: RAILIANCE-WP-0015-T03
status: done
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.

**Closed 2026-07-22:** `manifests/cnpg-option-a-backup.yaml` applied (CronJobs
02:30–02:45 UTC). Immediate success wave via `tools/cnpg-logical-backup.sh`
uploaded encrypted dumps for all consumer databases and wrote
`cnpg-option-a-status`.

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

```task
id: RAILIANCE-WP-0015-T04
status: done
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.

**Closed 2026-07-22:** status tool checks Option A CronJobs + last-success
freshness (and still accepts barman ScheduledBackup). RESULT: ok for all four
clusters.

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

```task
id: RAILIANCE-WP-0015-T05
status: done
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.

**Closed 2026-07-22:** decrypted Option A `vergabe_db` age artifact; isolated
restore row-gate 195/195; status healthy; evidence in
`docs/evidence/cnpg-option-a-backup-20260722.json`.
