+# Backup-Automation Architektur
+
+## Überblick
+
+Das System automatisiert Backups aller in Netbox gekennzeichneten Systeme mit:
+- **Borg Backup** für deduplizierte, verschlüsselte Backups
+- **Kestra** für Workflow-Orchestrierung
+- **Ansible** für standardisierte Installation
+- **Rclone** für S3-Replication
+- **Hetzner S3** für Offsite-Storage
+
+## Komponenten
+
+### 1. Netbox Integration
+- **Quelle der Wahrheit**: Netbox IPAM + Inventar
+- **Markierung**: TAG `backup=true` auf Systemen
+- **API**: REST für dynamische Abfragen
+- **Update-Frequenz**: Täglich
+
+### 2. Kestra Orchestration
+- **Rolle**: Zentrale Workflow-Engine
+- **Auslöser**: Systemd Timer (02:00 Uhr täglich)
+- **Aufgaben**:
+  1. Netbox abfragen → Liste Backup-Systeme
+  2. SSH-Keys prüfen/generieren
+  3. Ansible Playbook starten
+  4. Status erfassen
+- **Fehlerbehandlung**: Retry-Logik, Notifications
+
+### 3. Ansible Automation
+- **Playbooks**:
+  - `install-borg-client.yaml` - Clients Setup
+  - `configure-backup-server.yaml` - Server Setup
+  - `update-backup-config.yaml` - Config Updates
+
+- **Roles**:
+  - `borg-client` - Borg Installation
+  - `backup-server` - Server + Rclone
+
+- **Inventory**: Dynamisch aus Netbox (via Kestra)
+
+### 4. Borg Backup
+- **Format**: Deduplicating, Encrypting, Compressing Backup
+- **Encryption**: AES-256-CTR
+- **Compression**: LZ4 (schnell) oder Zstd (besser)
+- **Retention**: 7 tägl., 4 wöchentl., 12 monatl.
+- **Repository-Struktur**:
+  ```
+  /backup/repos/{hostname}/
+  ├── data/
+  ├── index.*/
+  ├── hints
+  └── nonce
+  ```
+
+### 5. Backup-Server
+- **Rolle**: Zentrale Sammelstelle aller Backups
+- **User**: `backup:backup` mit restricted SSH
+- **Verzeichnis**: `/backup/repos/{hostname}`
+- **SSH-Zugang**: Nur für `borg serve`
+
+### 6. Docker-Spezifika
+- **Pre-Backup Hooks**: MySQL/PostgreSQL Dumps
+- **Named Volumes**: Automatisch exportiert
+- **Compose-Dateien**: Backup als YAML
+- **Cleanup**: Alte Dumps regelmäßig löschen
+
+### 7. Rclone S3-Sync
+- **Quelle**: `/backup/repos` (Backup-Server)
+- **Ziel**: `hetzner:mbo-backups/production/repos/`
+- **Strategie**: Incremental Sync
+- **Timing**: 04:00 Uhr täglich (nach Borg)
+- **Paralleler**: 4 Transfers, 8 Checkers
+
+### 8. Hetzner S3
+- **Bucket**: `mbo-backups`
+- **Struktur**: `production/repos/{hostname}/{archive}`
+- **Versionierung**: Optional aktivierbar
+- **Lifecycle**: Optional für alte Versionen

+
+## Timing & Ablauf
+
+| Zeit | Komponente | Aktion |
+|------|------------|--------|
+| **02:00** | Kestra Timer | Startet Workflow |
+| 02:05-02:30 | Netbox API | Lädt Liste aller zu backupenden Hosts |
+| 02:30-02:45 | Ansible | Deployed/Updated Borg auf allen Clients |
+| **03:00** | Systemd Timer | Startet Backup auf allen Clients |
+| 03:00-03:45 | Borg | Backups laufen parallel auf allen Hosts |
+| - | Docker Hooks | MySQL/PG Dumps, Volume Exports |
+| - | SSH | Archivs gehen an Backup-Server |
+| **04:00** | Rclone Timer | Startet S3-Sync |
+| 04:00-04:30 | Rclone | Sync zu Hetzner S3 |
+
+## Skalierbarkeit
+
+### Horizontal (mehr Hosts)
+- **Borg**: Parallelisierung via SSH
+- **Kestra**: Workflow-Engine skaliert linear
+- **Rclone**: Multi-threaded, weitere --transfers falls nötig
+- **S3**: Unbegrenzt
+
+### Vertikal (größere Datenmengen)
+- **Borg**: Kompression + Deduplizierung spart 50-70%
+- **Backup-Server**: NVMe für Speed, großes Volume für Speicher
+- **S3**: Skalierung automatic
+
+### Parallelität
+```yaml
+Max parallel Backups: Anzahl der Clients × CPU-Kerne
+Empfehlung: Nice-Priorität senken, CPU-Limits setzen
+```
+
+## Sicherheit
+
+### Verschlüsselung
+- **Borg**: AES-256-CTR Encryption
+- **Passphrase**: Via Ansible Vault gespeichert
+- **Transport**: SSH (Ed25519 Keys)
+
+### Zugriffskontrolle
+- **SSH Keys**: Pro Client eindeutig
+- **SSH Restrictions**: `restrict,command=...` auf Server
+- **Backup-User**: Minimal privileges
+- **S3 Credentials**: Via Vault/Secrets
+
+### Audit & Logging
+- **Journald**: Alle Backup-Logs in Systemd
+- **Dateilogging**: `/var/log/mbo-backup/*.log`
+- **Rclone**: Detailed Logs für S3-Sync
+- **Kestra**: Workflow Execution History
+
+## Fehlerbehandlung
+
+### Backup-Fehler
+1. Borg versucht 3x neu (systemd Restart)
+2. Fehler geht in Log
+3. Kestra prüft Exit-Code
+4. Optional: Notification an Admin
+
+### SSH-Fehler
+1. SSH retry mit exponential backoff
+2. Key-Rotation wenn nötig
+3. Fallback: Manual trigger
+
+### S3-Fehler
+1. Rclone retry mit backoff
+2. Partial sync wird fortgesetzt
+3. Alert bei persistent failure
+
+## Monitoring & Observability
+
+### Metriken
+- Backup-Größe pro Host
+- Deduplizierung-Ratio
+- Execution-Zeit
+- S3-Upload-Speed
+- Retention-Policy Compliance
+
+### Logs
+- Systemd Journal: `journalctl -u mbo-backup`
+- File-basiert: `/var/log/mbo-backup/*.log`
+- Kestra: Execution History
+- Rclone: `--log-level INFO/DEBUG`
+
+### Alerting
+- Backup Failure → Alert
+- S3-Sync Failed → Alert
+- Disk Space Low → Alert
+- SSH Key Expiry → Alert (optional)
+
+## Disaster Recovery
+
+### RTO/RPO Zielsetzungen
+- **RTO** (Recovery Time Objective): < 2 Stunden
+- **RPO** (Recovery Point Objective): < 24 Stunden
+
+### Restore-Optionen
+1. **Lokal vom Backup-Server**: Schnell, kein Internet nötig
+2. **Von Hetzner S3**: Geo-redundant, asynchron
+3. **Selective Restore**: Einzelne Dateien/Volumes
+
+### Test-Strategie
+- Monatlich: Restore-Drill eines Vollsystems
+- Quarterly: S3-Restore-Test
+- Nach Major Changes: Schnell-Sanity-Check

+# Getting Started - Backup-Automation Setup
+
+Schnelleinstieg für MBO-Tech-IT Backup-Automation.
+
+## Schritt 1: Repository klonen
+
+```bash
+git clone https://gitea.mbo-tech-it.de/jonny/backup-automation.git
+cd backup-automation
+```
+
+## Schritt 2: Secrets vorbereiten
+
+```bash
+# Erstelle secrets.env Datei (NICHT commiten!)
+cat > secrets.env << 'EOF'
+export NETBOX_TOKEN="your-netbox-api-token-here"
+export NETBOX_URL="https://netbox.mbo-tech-it.de"
+export HETZNER_S3_ACCESS_KEY="your-s3-access-key"
+export HETZNER_S3_SECRET_KEY="your-s3-secret-key"
+export HETZNER_S3_REGION="fsn1"
+EOF
+
+chmod 600 secrets.env
+source secrets.env
+```
+
+## Schritt 3: Backup-Server vorbereiten
+
+```bash
+# SSH zum zukünftigen Backup-Server
+ssh root@backup.mbo-tech-it.de
+
+# Ansible installieren
+apt update && apt install -y ansible
+
+# Ansible Playbook ausführen
+cd /tmp/backup-automation
+ansible-playbook ansible/playbooks/configure-backup-server.yaml \
+  -e "hetzner_s3_access_key=$HETZNER_S3_ACCESS_KEY" \
+  -e "hetzner_s3_secret_key=$HETZNER_S3_SECRET_KEY"
+```
+
+## Schritt 4: Netbox vorbereiten
+
+### In Netbox UI:
+1. Gehe zu **Admin** → **Extras** → **Tags**
+2. Klicke **Add Tag**
+3. Setze:
+   - **Name**: `backup`
+   - **Slug**: `backup`
+   - **Color**: Orange
+
+### Systeme taggen:
+1. Gehe zu **DCIM** → **Devices**
+2. Für jedes zu backupendes System:
+   - Öffne Device
+   - Unter **Tags** → `backup` hinzufügen
+   - Save
+
+Oder via API:
+```bash
+DEVICE_ID=123
+curl -X PATCH https://netbox.mbo-tech-it.de/api/dcim/devices/$DEVICE_ID/ \
+  -H "Authorization: Token $NETBOX_TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{"tags": [{"name": "backup"}]}'
+```
+
+## Schritt 5: Kestra Workflow einrichten
+
+```bash
+# Workflow hochladen
+curl -X POST https://kestra.mbo-tech-it.de/api/v1/flows \
+  -H "Content-Type: application/yaml" \
+  -d @kestra/workflows/backup-provision.yaml
+
+# Oder via UI:
+# 1. Login zu https://kestra.mbo-tech-it.de
+# 2. Create Flow → Upload YAML
+# 3. Speichern
+```
+
+## Schritt 6: Secrets in Kestra setzen
+
+In Kestra UI:
+1. **Settings** → **Secrets**
+2. Füge diese Secrets hinzu:
+   ```
+   NETBOX_TOKEN = (dein Token)
+   NETBOX_URL = https://netbox.mbo-tech-it.de
+   HETZNER_S3_ACCESS_KEY = (dein S3 Access Key)
+   HETZNER_S3_SECRET_KEY = (dein S3 Secret)
+   ```
+
+## Schritt 7: Erste Test-Ausführung
+
+```bash
+# Manuell triggern (nicht warten auf 02:00 Uhr):
+# In Kestra UI: automation → backup-provision → Execute
+
+# Oder via API:
+curl -X POST https://kestra.mbo-tech-it.de/api/v1/namespaces/automation/flows/backup-provision/executions \
+  -H "Content-Type: application/json"
+```
+
+Logs anschauen:
+```bash
+# SSH auf Backup-Server
+journalctl -u mbo-rclone-sync -f
+
+# SSH auf Client
+journalctl -u mbo-backup -f
+tail -f /var/log/mbo-backup/*.log
+```
+
+## Schritt 8: Überprüfe Backup-Status
+
+```bash
+# Auf Backup-Server
+ssh backup@backup.mbo-tech-it.de
+
+# Zeige alle Borg Repos
+ls -la /backup/repos/
+
+# Zeige Archive eines Systems
+borg list /backup/repos/SERVERNAME
+
+# Zeige Größe & Statistik
+borg info /backup/repos/SERVERNAME
+```
+
+## Schritt 9: Überprüfe S3-Sync
+
+```bash
+# SSH auf Backup-Server
+ssh root@backup.mbo-tech-it.de
+
+# Manuelle Rclone Sync
+sudo -u backup rclone sync --progress \
+  /backup/repos hetzner:mbo-backups/production/repos
+
+# Überprüfe S3 Bucket
+sudo -u backup rclone ls hetzner:mbo-backups/production/repos
+```
+
+## Schritt 10: Automatisierung starten
+
+In Kestra UI:
+1. Öffne **automation** → **backup-provision**
+2. Überprüfe Schedule: `0 2 * * *` (täglich 02:00)
+3. Überprüfe, dass Enabled = `true`
+4. Speichern
+
+Jetzt läuft das System automatisch täglich! 🚀
+
+---
+
+## Troubleshooting
+
+### SSH-Fehler?
+```bash
+# Test SSH vom Client zum Backup-Server
+ssh -i /root/.ssh/mbo-backup-key.ed25519 \
+  backup@backup.mbo-tech-it.de "echo OK"
+
+# Falls Fehler: SSH-Key regenerieren
+ssh-keygen -t ed25519 -N '' -f /root/.ssh/mbo-backup-key.ed25519
+```
+
+### Borg nicht installiert?
+```bash
+# Manuell auf Host:
+apt install -y borgbackup
+
+# Oder via Ansible:
+ansible-playbook -i inventory.ini \
+  ansible/playbooks/install-borg-client.yaml
+```
+
+### Rclone S3 Fehler?
+```bash
+# Teste S3 Verbindung
+sudo -u backup rclone ls hetzner:mbo-backups/
+
+# Falls Fehler: Config prüfen
+sudo -u backup rclone config show hetzner
+```

+
+## Phase 2: Git-Repository Setup
+
+- [ ] Repository lokal clonen
+- [ ] Verzeichnisstruktur erstellen:
+  ```
+  backup-automation/
+  ├── kestra/
+  │   └── workflows/
+  ├── ansible/
+  │   ├── playbooks/
+  │   ├── roles/
+  │   └── group_vars/
+  ├── scripts/
+  ├── docs/
+  └── README.md
+  ```
+- [ ] Alle Dateien ins Repo pushen
+- [ ] `.gitignore` hinzufügen:
+  ```
+  .ansible-vault-pass
+  *.key
+  *.pem
+  ~/.ssh/
+  vault.yml
+  inventory/dynamic
+  .env
+  ```
+
+## Phase 3: Backup-Server einrichten
+
+- [ ] Server online bringen & SSH-Zugang testen
+- [ ] Ansible auf Server installieren: `apt install ansible`
+- [ ] SSH-Keys generieren:
+  ```bash
+  ssh-keygen -t ed25519 -N '' -f /root/.ssh/mbo-backup-key.ed25519
+  ```
+- [ ] Ansible Playbook ausführen:
+  ```bash
+  ansible-playbook ansible/playbooks/configure-backup-server.yaml \
+    -e "hetzner_s3_access_key=YOUR_KEY" \
+    -e "hetzner_s3_secret_key=YOUR_SECRET"
+  ```
+- [ ] Borg Repositories initialisieren pro Server
+- [ ] Rclone S3-Verbindung testen:
+  ```bash
+  sudo -u backup rclone ls hetzner:mbo-backups/
+  ```
+- [ ] Systemd Timers aktivieren:
+  ```bash
+  systemctl status mbo-rclone-sync.timer
+  ```
+
+## Phase 4: Netbox Tags setzen
+
+- [ ] In Netbox Admin: Tag `backup=true` erstellen
+- [ ] Tag zu allen zu backupenden Systemen hinzufügen
+- [ ] Mindestens 2-3 Test-Systeme markieren
+
+## Phase 5: Kestra Workflow
+
+- [ ] Kestra-Workflow YAML ins System laden:
+  ```bash
+  curl -X POST https://kestra.mbo-tech-it.de/api/v1/flows \
+    -H "Content-Type: application/yaml" \
+    -d @kestra/workflows/backup-provision.yaml
+  ```
+- [ ] Secrets in Kestra setzen:
+  - [ ] `NETBOX_TOKEN` = dein API Token
+  - [ ] `NETBOX_URL` = https://netbox.mbo-tech-it.de
+  - [ ] `HETZNER_S3_KEY` = S3 Access Key
+  - [ ] `HETZNER_S3_SECRET` = S3 Secret Key
+
+- [ ] Workflow manuell triggern & testen:
+  ```
+  Kestra UI → automation → backup-provision → Execute
+  ```
+
+## Phase 6: Client Setup (pro Host)
+
+- [ ] Auf jedem Client (manuell oder via Kestra):
+  ```bash
+  # Ansible ausführen
+  ansible-playbook -i inventory.ini \
+    ansible/playbooks/install-borg-client.yaml
+  ```
+  
+- [ ] Pro Host Überprüfung:
+  - [ ] Borg installiert? `borg --version`
+  - [ ] SSH-Key kopiert? `ls -la ~/.ssh/mbo-backup-key.ed25519`
+  - [ ] Systemd Timer aktiv? `systemctl status mbo-backup.timer`
+  - [ ] Script vorhanden? `ls -la /usr/local/bin/mbo-backup/`
+
+## Phase 7: Erste Test-Backups
+
+- [ ] Auf Test-Server manuell Backup starten:
+  ```bash
+  systemctl start mbo-backup.service
+  ```
+  
+- [ ] Logs überprüfen:
+  ```bash
+  journalctl -u mbo-backup -f
+  tail -f /var/log/mbo-backup/backup-*.log
+  ```
+
+- [ ] Auf Backup-Server Repository prüfen:
+  ```bash
+  ssh backup@backup.mbo-tech-it.de
+  borg list /backup/repos/TEST_SERVER
+  borg info /backup/repos/TEST_SERVER
+  ```
+
+- [ ] S3-Sync überprüfen:
+  ```bash
+  # Nach Rclone-Timer (04:00)
+  rclone ls hetzner:mbo-backups/production/repos/
+  ```
+
+## Phase 8: Automatisierung aktivieren
+
+- [ ] In Kestra: Timer aktivieren (täglich 02:00 Uhr)
+- [ ] Kestra-UI überwachen:
+  - [ ] Erste Nacht Log-Ausgaben prüfen
+  - [ ] Fehler oder Warnings?
+
+- [ ] SSH-Key Restrictions konfigurieren (Security-Hardening):
+  ```bash
+  # Auf Backup-Server authorized_keys anpassen:
+  restrict,command="/usr/bin/borg serve --restrict-to-paths /backup/repos" ssh-ed25519 AAAA...
+  ```
+
+## Phase 9: Monitoring & Alerting (optional)
+
+- [ ] Prometheus für Backup-Metriken (optional)
+- [ ] Alerting via Alertmanager (optional)
+- [ ] Webhook zu MatterMost/Slack (optional)
+
+## Phase 10: Dokumentation & Schulung
+
+- [ ] README aktualisieren mit eigenen Pfaden
+- [ ] Team-Training: Restore-Proceduren
+- [ ] Runbook für emergencies
+- [ ] Disaster Recovery Test planen
+
+---
+
+## 🔍 Häufige Probleme
+
+### "SSH connection refused"
+- SSH-Key nicht auf Backup-Server? `ssh-copy-id` nutzen
+- Firewall blockiert? Port 22 open?
+- SSH-Service läuft? `systemctl status ssh`
+
+### "Borg: Repository not found"
+- Repository nicht initialisiert? Manually: `borg init /backup/repos/HOSTNAME`
+- Pfad falsch? Check: `ansible_hostname` muss mit Verzeichnis passen
+
+### "Rclone: Access Denied to S3"
+- Credentials falsch? `rclone config show hetzner`
+- S3-Bucket nicht existent? `rclone mkdir hetzner:mbo-backups`
+- Region falsch? Hetzner FSN1 vs NBG1 unterschied?
+
+### "Docker dumps failing"
+- Docker nicht installiert? Script skipped automatisch
+- Container nicht gelabelt? Label setzen: `docker label backup.mysql=true`
+- DB-Dumps zu groß? Kompression anpassen
+
+---
+
+## ✅ Erfolgs-Indikatoren
+
+- ✅ Kestra Workflow läuft täglich
+- ✅ Systemd Timers alle `enabled`
+- ✅ Logs zeigen "Backup completed successfully"
+- ✅ Rclone syncronisiert zu S3
+- ✅ S3 zeigt Daten: `rclone ls hetzner:mbo-backups/production/repos/`

+## Ablauf:
+
+1. **Kestra startet täglich** (z.B. 02:00)
+2. **Abfrage Netbox API**: Alle Systeme mit TAG `backup=true`
+3. **Pro System**: Trigger Ansible gegen diesen Host
+4. **Ansible**: 
+   - Prüft ob Borg installiert
+   - Wenn nicht: installiert + konfiguriert
+   - Stellt Backup-Scripts bereit
+   - Startet Borg Backup via Systemd
+5. **Borg läuft** auf jedem Host (inkrementell)
+6. **Backup-Server** sammelt alle Borg-Repos
+7. **Rclone** syncronisiert nightly nach S3
