HELBACKUP

Docker app from Kreuzbube88's Repository

Overview

HELBACKUP is a self-hosted backup orchestrator built specifically for Unraid. One container, full control — no cloud dependency, no subscription.


Backup Types:

✓ Flash Drive — Incremental rsync of /boot with SHA-256 verification

✓ Appdata — Optional container stop/start, Docker config export included

✓ Virtual Machines — Libvirt snapshot, vDisk rsync, XML config export

✓ Docker Images — Save images as .tar archives via Docker API

✓ System Config — Network, users, shares, plugins, disk assignments


Targets:

✓ Remote NAS / Server — SSH + Rsync with optional strict host-key pinning

✓ Local Filesystem — Direct path on the Unraid array

✓ NAS Power Management — Wake-on-LAN before backup, auto-shutdown after


Job Engine:

✓ Visual Job Builder — Drag-and-drop step ordering with dependency graph

✓ Retry Logic — Linear or exponential backoff per step

✓ Pre/Post Hook Scripts — Run custom scripts around backup jobs

✓ Catch-Up on Start — Runs missed schedules after container restart

✓ Checksum Verification — SHA-256 validation for all backup files


Retention:

✓ Simple Retention — Keep last N backups with configurable minimum

✓ GFS Rotation — Grandfather-Father-Son: Daily / Weekly / Monthly, saves up to 90% storage


Security & Encryption:

✓ AES-256 Encryption — Optional end-to-end GPG encryption with recovery key

✓ First-Run Setup — No default passwords, admin account created on first access

✓ API Tokens — Scoped tokens with optional expiry

✓ Webhooks — HMAC-signed event delivery


Recovery:

✓ Granular File Restore — Browse and restore individual files or directories

✓ Full Server Restore Wizard — Step-by-step guided recovery for all backup types

✓ Flash Drive Restore — Complete /boot restoration with confirmation guard


Monitoring & Notifications:

✓ 7 Notification Channels — Email, Gotify, ntfy, Pushover, Telegram, Discord, Slack

✓ Live Logs — Real-time backup progress via SSE stream

✓ Dashboard — System status, per-target storage, 30-day history chart

✓ Prometheus Metrics — Ready-made monitoring integration

✓ German & English UI — Full i18n support
