# Backup — sidecar approach
#
# Wealthfolio has no PG/MySQL support (Diesel ORM hard-wired to SQLite per
# upstream README). The data lives on an RWO PVC that's held 24/7 by the
# main WF pod, so a separate backup CronJob would hit a Multi-Attach error
# (confirmed 2026-04-18 test).
#
# Instead, the WF Deployment gets a backup sidecar:
# - Shares the data PVC read-only + the NFS backup target.
# - Runs busybox `crond` with a 04:30-daily entry.
# - Uses `sqlite3 .backup` (WAL-safe, no downtime) to snapshot into an
#   NFS dated folder + retains 30 days.
#
# See `resource "kubernetes_deployment" "wealthfolio"` above — the sidecar
# is wired in via the deployment's container/volume blocks.

############################################################################
# Daily portfolio-recalc CronJob — keeps the Grafana wealth dashboard fresh.
#
# Wealthfolio writes new `daily_account_valuation` rows ONLY when a
# PortfolioJob fires with ValuationRecalcMode != None. None of its built-in
# schedulers do that for our deployment:
#   * Internal 6h quote scheduler — refreshes the `quotes` table only.
#   * Internal 4h broker scheduler — short-circuits if `sync_refresh_token`
#     is unset (it is — we route broker imports through the external
#     wealthfolio-sync CronJob).
# Result: valuations only update when the Tauri/web UI hits
# /api/v1/market-data/sync — i.e. when someone opens the dashboard.
#
# This CronJob mimics that: login → POST /api/v1/market-data/sync. The
# server runs the portfolio job (Incremental quote sync + IncrementalFromLast
# valuation recalc), backfilling missing daily_account_valuation rows up to
# today. The pg-sync sidecar's :07 hourly tick mirrors them to PG, and
# Grafana auto-refreshes within 5 min.
#
# Schedule 16:00 UTC (= 17:00 BST in summer):
#   - After UK market close (15:30 UTC BST), so EOD UK prices are settled
#   - US market open ~2.5h (good intra-day US quotes)
#   - pg-sync next tick at 16:07 → Grafana fresh by ~16:12 UTC ≈ 17:12 BST,
#     well before the 18:00 BST "fresh data by 6pm" target.
#
# Plaintext password lives at Vault `secret/wealthfolio.web_password`,
# pulled into the existing `wealthfolio-secrets` K8s Secret by the
# `dataFrom.extract` ExternalSecret above (no extra ESO wiring needed —
# the new key flows through automatically).
