No backup strategy is documented or implemented.

What needs backing up

  1. Longhorn volumes — configure Longhorn backup to NFS/S3
  2. MySQL (CrowdSec, Homarr) — scheduled mysqldump cronjob
  3. PostgreSQL (Forgejo via CNPG) — CNPG has built-in backup, configure it
  4. External MariaDB (K3s datastore on bare metal) — mysqldump cronjob
  5. Authelia/lldap — backup PVC data

Steps

  1. Configure Longhorn backup target (NFS or S3-compatible)
  2. Create a CronJob for MySQL dumps → store in Longhorn PVC or NFS
  3. Configure CNPG backup for Forgejo PostgreSQL
  4. Document the backup/restore procedure in README
