Add k8s-native backup/restore scripts for the 5 live apps
backup-myapps.sh/restore-myapps.sh only ever knew about Docker volumes, which no longer exist for n8n/odoo/mautic/nextcloud/frappe now that they're all running in k3s — nightly backups have been silently hollow for these apps since the migration. These new scripts capture/restore each app's k8s manifests, Secret, DB (pg_dump/mysqldump via kubectl exec), and app-data PVC contents (kubectl exec tar, never raw filesystem access), reusing the existing local+VM+R2 3-2-1 storage/retention logic unchanged. Tested standalone: full backup of all 5 apps produces verified non-empty manifests/secrets/DB dumps/PVC data; restore-in-place tested end-to-end against n8n (DB row counts and PVC data matched exactly pre/post, app verified healthy over HTTPS). Not wired into management-platform yet (app.py stays untouched) — restore script also doesn't yet handle a fresh/DR cluster where the PVCs and their manifests don't already exist (same-cluster restore only for now).

# backup-k8s-apps.sh — k8s-native replacement for backup-myapps.sh
|
||||||
|
# Backs up: n8n, Odoo, Mautic, Nextcloud, Frappe/ERPNext (all live in k3s)
|
||||||
|
#
|
||||||
|
# Per app, captures:
|
||||||
|
# - k8s manifests (Deployment/Service/ConfigMap/Ingress, via `kubectl get -o yaml`)
|
||||||
|
# - Secret manifest (plaintext for now — encryption-at-rest explicitly deferred)
|
||||||
|
# - DB dump (pg_dump / mysqldump via `kubectl exec`, never a raw PGDATA/datadir copy)
|
||||||
|
# - App-data PVC contents (via `kubectl exec ... tar`, never raw filesystem access —
|
||||||
|
# see migration-status.md §5, sandbox-filesystem-divergence rule)
|
||||||
|
#
|
||||||
|
# Storage tiers (logic reused verbatim from backup-myapps.sh, just repointed at the
|
||||||
|
# new archive name/contents):
|
||||||
|
# 1. Local → /root/backups/ (CRITICAL — always runs)
|
||||||
|
# 2. VM → SSH tunnel → /backups/cloudproject/
|
||||||
|
# 3. Cloud → Cloudflare R2 (S3-compatible, optional)
|
||||||
|
#
|
||||||
|
# NOTE: R2 and VM failures do NOT stop the backup. Local backup always completes first.
|
||||||
|
#
|
||||||
|
# Archive name is deliberately NOT "myapps-backup-*" (the legacy Docker-era pattern
|
||||||
|
# still produced nightly by /root/backup-myapps.sh via cron) — using a distinct
|
||||||
|
# "myapps-k8s-backup-*" prefix keeps the two backup lineages from mixing in the same
|
||||||
|
# retention pool / R2 prefix until the legacy cron job is explicitly retired.
