# 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.
