Owner

Backups carry the same priority as o11y. ser8 (home 2, 857G free) becomes the backup target for kai-server's stateful data, giving a true offsite second copy.

Backup set (from the 2026-06-12 PVC inventory)

forgejo-data (20Gi) and forgejo-db-data (5Gi) - the crown jewels, every repo and issue
registry-data (20Gi) - per Kai: include it
coilysiren-backend db (5Gi)
ntfy-data (5Gi)
host-level game saves (~/saves on kai-server)

Excluded: metrics and traces (re-collectable), runner scratch PVCs.

Design

restic, pushed from kai-server nightly via systemd timer (generalize the existing factorio-backup.timer pattern). Encrypted, deduped. Keep policy 7 daily / 4 weekly / 3 monthly, matching the 3-month o11y horizon.
restic rest-server on ser8 in append-only mode, as a plain systemd service, NOT in k3s. Append-only means kai-server cannot delete or corrupt its own history even if compromised. Host-level means backups work while k3s is down - the target must be more reliable than what it backs.
Disk partition of ser8's 857G: o11y ~170Gi, backup repo ~300Gi envelope, remainder margin.
Phase 2: third copy of the irreplaceable subset (forgejo, saves) to S3 with a Glacier lifecycle. Off the data path, so it does not violate the no-elective-dependencies thesis.
Restore drills are part of done: an untested backup is a hope, not a backup. Quarterly restore of forgejo-data into a scratch namespace on ser8's cluster.

Priority peer to the o11y burn-down. Sequencing: needs nothing from the o11y stack, can land in parallel any time. Restic repo path and SSM-stashed repo password to be indexed in SSM.md on creation.

🛫 ward pre-flight: NO-GO

ward agent headless --driver claude ran a pre-flight feasibility read on this issue before detaching a fire-and-forget run, and the agent judged it NO-GO - it should not be carried unattended until a human weighs in.

requires destructive live-host operations (ser8 disk partitioning), two-host systemd convergence, SecureString creation, and a restore-drill done-condition that can't be satisfied or verified from an ephemeral clone — a human should drive the hardware steps.

No container was launched. Review the issue (clarify the scope, resolve the unknown, or split it), then re-dispatch - ward agent headless --driver claude <ref> --no-preflight skips this gate once you've decided it's good to go.

full pre-flight read

This issue bundles real hardware mutation that a fresh-clone container can't safely carry alone: partitioning ser8's 857G disk, installing/enabling systemd services on two physical hosts (kai-server and ser8), creating a SecureString SSM repo-password, and — explicitly in the done-condition — running a restore drill that requires live cluster access. The authoring half (an ansible role for the append-only rest-server, a restic-push systemd timer generalizing factorio-backup.timer, SSM.md indexing) is well-specified and codeable, but it can't be verified to merge-quality without converging against the live boxes, and disk partitioning of a live host is exactly the irreversible/destructive class that should not run unattended. There's also a genuine design fork left open (the 857G partition layout: o11y ~170Gi / backup ~300Gi / margin) where a wrong commit is costly to undo on a disk already holding o11y data.

NO-GO: requires destructive live-host operations (ser8 disk partitioning), two-host systemd convergence, SecureString creation, and a restore-drill done-condition that can't be satisfied or verified from an ephemeral clone — a human should drive the hardware steps.

🔒 Reserved by ward agent --harness codex — container engineer-codex-infrastructure-320 on host kais-macbook-pro-2.local is carrying this issue (reserved 2026-07-08T17:09:56Z). Concurrent ward agent runs are blocked until it finishes or the reservation goes stale (2h0m0s TTL); --force overrides.

Do not comment on or edit this issue to steer the run while it is reserved. The engineer seeded the body once at launch and never re-reads it, so a comment or edit reaches only human readers, never the running engineer. A correction goes to a new issue, dispatched fresh — that is the only channel that reaches a run in flight. Where the forge supports it, ward locks this conversation to make that a road-block rather than a convention (ward#494).

Issue body as seeded:

Backups carry the same priority as o11y. ser8 (home 2, 857G free) becomes the backup target for kai-server's stateful data, giving a true offsite second copy.

## Backup set (from the 2026-06-12 PVC inventory)

- forgejo-data (20Gi) and forgejo-db-data (5Gi) - the crown jewels, every repo and issue
- registry-data (20Gi) - per Kai: include it
- coilysiren-backend db (5Gi)
- ntfy-data (5Gi)
- host-level game saves (~/saves on kai-server)

Excluded: metrics and traces (re-collectable), runner scratch PVCs.

## Design

- restic, pushed from kai-server nightly via systemd timer (generalize the existing factorio-backup.timer pattern). Encrypted, deduped. Keep policy 7 daily / 4 weekly / 3 monthly, matching the 3-month o11y horizon.
- restic rest-server on ser8 in append-only mode, as a plain systemd service, NOT in k3s. Append-only means kai-server cannot delete or corrupt its own history even if compromised. Host-level means backups work while k3s is down - the target must be more reliable than what it backs.

- Restore drills are part of done: an untested backup is a hope, not a backup. Quarterly restore of forgejo-data into a scratch namespace on ser8's cluster.

Priority peer to the o11y burn-down. Sequencing: needs nothing from the o11y stack, can land in parallel any time. Restic repo path and SSM-stashed repo password to be indexed in SSM.md on creation.

Static container doctrine and seed boilerplate are identical every run and omitted here (they ride ward v0.451.0).

WARD-OUTCOME: done - restic offsite backup stack to ser8 landed

The backup wiring was straightforward once I stopped pretending the PVCs could be handled as one generic path list. The only real pushback was the docs size cap and the missing heterogeneous review family, so I split the restic details into a separate runbook and accepted an advisory-only panel. Confidence is good on the host-level wiring. The rough edge is still operational: the first restore drill has to prove the PVC-backed pieces are actually consistent.
