Plan Backup Dr

name: plan-backup-dr
description: >
  Audit whether a project can actually recover from data loss — not just whether
  backups exist — then emit a phased DR plan. Use when "can we recover if the DB
  dies", "audit our backups", "what's our RPO/RTO", or "disaster recovery". Plan
  only. Destructive-op gates stay on plan-data-integrity.

# plan-backup-dr — Recovery capability plan

**Degree of freedom: HIGH** — prove restore, quantify RPO/RTO, plan.
Stay **plan-only**. No PITR toggles or prod-writing drills until approved.

**Role:** Platform / disaster-recovery engineer.

**Task:** Prove restore works, quantify RPO/RTO, emit `plan-backup-dr.md`.
**Audit & plan only — no PITR toggles, lifecycle edits, or drills that write
to prod until approved.**

**Backup existence is not recovery capability.** An untested backup is a hope.

## This skill vs neighbors

| Skill | Owns |
|---|---|
| **plan-backup-dr** (this) | Can you restore? RPO/RTO, drill evidence, SPOF |
| `plan-data-integrity` | Stop destructive ops *going forward* (unguarded DELETE/DROP) |
| `audit-env-parity` | Staging pointing at prod data (blast-radius setup) |
| `audit-infra-cost` | Backup retention that silently explodes the bill |
| `plan-secrets-audit` | Credential exposure — not "can I reconstruct secrets after loss" |

Do **not** fire for "is this migration safe / agent might delete prod" →
`plan-data-integrity`. That skill *prevents* wipe; this one *recovers* after one.

## How to reason (every plan item)

1. **Propose** — backup, restore path, drill, or off-provider export
2. **Risk** — worst-case in plain language ("lose up to a day of uploads")
3. **Keep-working** — stores that already have a proven restore
4. **Phase** — P0 / P1 / P2 (do not execute)

## Worked example

> **Propose:** run one isolated restore drill of the primary DB; write the
> runbook from what you actually did.
> **Risk:** daily snapshot exists, never restored — RPO 24h is a hope, RTO unbounded.
> **Keep-working:** object-storage versioning already on.
> **Phase:** P0 — no proven restore.
> **Target:** drill into an isolated env, never over prod.

## Phase 0 — Map the recovery surface  [HIGH freedom]

For each stateful thing, find backup *and* restore:

- **Primary DB** (Supabase/Postgres): PITR? snapshots? retention? who restores?
- **Object storage:** versioning? lifecycle that *deletes*? backed up at all?
- **Secrets & config:** reconstructable if the account vanished?
- **Auth users:** identities recoverable, or only app rows?
- **External state:** Stripe, third-party subs, DNS, domain
- **Code & IaC:** reproducible from repo, or dashboard-only?

---

## Phase 1 — Audit recovery reality  [HIGH freedom]

**RPO** — Real gap between backups. Daily snapshot = up to 24h gone. PITR =
seconds. State the number, not the aspiration.

**RTO** — Walk the actual restore runbook. No runbook → RTO is unbounded.

**Restore drill** — Evidence a restore *succeeded* and was verified. None →
P0 is "run one end-to-end drill" (into an isolated env, never over prod).

**SPOF** — One provider/region/account. Billing/ToS/compromise suspends
everything? Off-provider export?

**Silent loss** — Lifecycle rules or `ON DELETE CASCADE` that erase more than
intended (cross-check `plan-data-integrity`). Backups that expire before anyone
would notice slow corruption.

**Bus-factor** — Restore credentials behind a login only one person has.

---

## Phase 2 — Phased DR plan (approve before executing)  [HIGH freedom — plan only]

- **P0** — no proven restore; any store with *no* backup; secrets unrecoverable; bus-factor-1
- **P1** — RPO worse than the data justifies; no written runbook; no off-provider export
- **P2** — RTO reduction, automated restore verify, drill cadence

Each item: current state, worst-case in plain language ("lose up to a day of
uploads"), target RPO/RTO, concrete change.

## Self-critique before the burndown  [LOW freedom — do not skip]

1. **RPO is a number** — not "we have backups"
2. **Drill evidence or P0** — absence is the finding
3. **No prod writes** — isolated env only, and only after approval
4. **Right owner** — unguarded DELETE → `plan-data-integrity`
5. **Do not cut restore** to save cost (`audit-infra-cost` must not expire backups)

## Definition of Done

- [ ] Every stateful store has backup AND restore method
- [ ] RPO stated as a real number per store
- [ ] RTO estimated from the actual (or absent) runbook
- [ ] Restore-drill evidence found — or absence flagged P0
- [ ] Secrets/config reconstructable
- [ ] SPOF + off-provider export status known
- [ ] Recovery-access bus-factor assessed
- [ ] Plan approved before infra change

## Output format

1. **Recovery surface** — store | backup | restore | RPO | RTO | last drill
2. **Findings** — issue | worst-case | severity | evidence
3. **SPOF map** — shared account/region/provider
4. **Phased DR plan** — P0/P1/P2 with target RPO/RTO
5. Await approval. Test restore only into an isolated env.
