- alert: update_failed (per-host, dedup=hostID) + fleet_update_halted
(system-scoped, host_id NULL via new RaiseOrTouchSystem helper).
- ws: UpdateWatcher tracks in-flight command.update dispatches and
reconciles them against incoming hello envelopes — success path
marks the job succeeded and auto-resolves the alert; 90s timeout
marks the job failed and raises update_failed.
- http: POST /api/hosts/{id}/update (admin-only JSON) + the HTMX
/hosts/{id}/update form variant. Pre-checks: host exists, online,
agent_version != current, no running update job. Refactored core
into Server.dispatchHostUpdate so the fleet worker can share it
without going through HTTP.
- fleetupdate: rolling worker iterating through host slots, halting
on first failure and raising fleet_update_halted. Polling-based
version-match (re-read hosts.agent_version every 1s up to 95s) —
no extra plumbing into the WS hello path. At-most-one-running is
enforced at the store layer (ErrFleetUpdateRunning).
- cmd/server: wire UpdateWatcher and FleetWorker into the main
goroutine; the worker uses a small serverDispatcher adapter that
delegates back into Server.DispatchHostUpdate.
Tests: watcher (success/timeout/mismatch/late-hello), HTTP endpoint
(happy + four pre-check branches + RBAC), worker (two-host happy,
timeout-halt, host-offline-halt, already-at-target skip, cancel
mid-run, double-Start guard).
restic-manager
Self-hosted, browser-based, single-pane-of-glass for managing restic backups across a fleet of Linux and Windows endpoints.
Status: pre-alpha. Phase 0 (project bootstrap) complete; Phase 1 (MVP) in progress. See
spec.mdfor the design andtasks.mdfor the roadmap.
What it does (target)
- Central visibility into backup state for every endpoint
- Trigger any restic operation remotely (
backup,forget,prune,check,unlock,snapshots,stats,diff,restore) - Manage per-host backup schedules from the UI
- Live job progress streamed back to the UI
- Restore wizard (browse snapshots, pick paths, restore to original or alternate host)
- Repo health surfacing (size, dedup ratio, last check, lock state)
- Alerting on failure or staleness
- Cross-platform agent (Linux + Windows)
- Ransomware-resistant repo access via append-only credentials
Architecture (one-line summary)
A small Go control-plane on the Proxmox host, lightweight Go agents on each
endpoint that hold an outbound WebSocket to the control-plane, and a
restic/rest-server on Unraid that holds the actual backup data. The
control-plane never touches backup bytes.

Local development
Requires Go 1.25+ (built and tested on 1.26). The floor is set by
modernc.org/sqlite v1.50.
make build # builds cmd/server and cmd/agent into ./bin
make test # runs go test ./...
make lint # runs golangci-lint
make run-server # runs the server (dev defaults)
