# Soteria PVC Restore Drill (backup.bstein.dev)

Use this runbook for a minimal production-safe restore drill after each meaningful Soteria change.

## Preconditions

- `maintenance` kustomization is reconciled and healthy in Flux.
- `soteria` and `oauth2-proxy-soteria` Deployments are ready in `maintenance`.
- Operator account is in Keycloak group `admin` or `maintenance`.
- Source PVC is not ephemeral/test throwaway storage that should be excluded from backup policy.

## Operator Flow (UI)

1. Open `https://backup.bstein.dev` and sign in through Keycloak.
2. In `PVC Inventory`, pick source namespace/PVC.
3. Click `Backup now` and wait for success response in `Last Action`.
4. Click `Restore`, choose a completed backup snapshot, and set:
   - `Target namespace`: destination namespace (defaults to source)
   - `Target PVC name`: unique drill PVC name (`restore-<source-pvc>-<date>`)
5. Click `Create restore PVC`.

## Verification

1. Confirm restore target exists:
   - `kubectl -n <target-namespace> get pvc <target-pvc>`
2. Confirm backup telemetry is present:
   - `kubectl -n monitoring port-forward svc/victoria-metrics-k8s-stack 8428:8428`
   - `curl -fsS 'http://127.0.0.1:8428/api/v1/query?query=max%20by%20(namespace%2Cpvc)(pvc_backup_age_hours)'`
3. Confirm alerting input stays healthy:
   - `pvc_backup_health{namespace="<source-namespace>",pvc="<source-pvc>"} == 1`

## Cleanup

1. Remove drill PVC after validation:
   - `kubectl -n <target-namespace> delete pvc <target-pvc>`
2. If a detached restore Longhorn volume remains, remove it in Longhorn UI/API.

## Failure Triage

- `401/403` on UI/API:
  - Verify oauth2-proxy group claims include `admin` or `maintenance`.
- Restore conflict:
  - Target PVC already exists; pick a new target PVC name.
- Freshness alert firing (`maint-soteria-refresh-stale`):
  - Check Soteria pod health and `/metrics` scrape reachability from `monitoring`.
- Unhealthy PVC alert firing (`maint-soteria-backup-unhealthy`):
  - Inspect `pvc_backup_health` and `pvc_backup_age_hours` for stale/missing backup coverage.
