Sprint 3 unified-master-audit closure. docs/operator/runbooks/postgres-backup.md
sections 110-143 still said 'certctl ships no backup CronJob template
in the Helm chart' and the three sample recipes that followed
included an 'in-cluster Postgres → S3' rollup that the operator
'should roll their own.' But the chart actually DOES ship that
CronJob:
deploy/helm/certctl/templates/backup-cronjob.yaml (Phase 4
DEPL-H2 closure, 2026-05-14) — opt-in via 'backup.enabled: true',
PVC + S3 sinks, pg_dump shape byte-comparable with the manual
command earlier in the runbook.
Operators following the pre-fix runbook would write a duplicate
CronJob from scratch while the working template sat unused under
their nose.
Rewrite of sections 110-143:
- Lead with the shipped CronJob, two install one-liners (PVC + S3).
- Move the recipes-by-topology block down to 'When the bundled
CronJob is NOT the answer' — still call out managed Postgres
(use provider PITR) and bare-VM Postgres (systemd + pg_dump +
restic) as deliberately out-of-scope.
- Add 'Recovery objectives' subsection: RPO ≈ 24h at the default
nightly schedule, RTO ≈ 30-60min from the existing drill steps
further down the page. Tells the reader where the bundled
CronJob fits in their RPO/RTO budget without overpromising
(anything below 24h RPO needs WAL-shipping, which the CronJob
doesn't do).
- Bump '> Last reviewed:' to today.
Closes DEPL-005.
