+
+## 🚀 Quick Start
+
+### 1. Netbox vorbereiten
+
+Füge das TAG `backup` mit Wert `true` zu allen Systemen hinzu, die gebackuped werden sollen:
+
+```bash
+# Via Netbox UI oder API:
+curl -X POST https://netbox.pve.mbo-tech-it.de/api/extras/tags/ \
+  -H "Authorization: Token YOUR_TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "name": "backup",
+    "slug": "backup",
+    "description": "System sollte gebackuped werden"
+  }'
+```
+
+### 2. Git-Repository clonen
+
+```bash
+git clone https://gitea.pve.mbo-tech-it.de/jonny/backup-automation.git
+cd backup-automation
+```
+
+### 3. Backup-Server vorbereiten
+
+```bash
+# SSH auf Backup-Server
+ssh root@backup.pve.mbo-tech-it.de
+
+# Ansible Playbook ausführen
+ansible-playbook -i localhost, \
+  ansible/playbooks/configure-backup-server.yaml \
+  -e "hetzner_s3_access_key=YOUR_KEY" \
+  -e "hetzner_s3_secret_key=YOUR_SECRET"
+```
+
+### 4. Kestra-Workflow hochladen
+
+```bash
+# Workflow in Kestra hochladen
+curl -X POST https://kestra.pve.mbo-tech-it.de/api/v1/flows \
+  -H "Content-Type: application/yaml" \
+  -d @kestra/workflows/backup-provision.yaml
+```
+
+### 5. Secrets in Kestra setzen
+
+```
+Settings → Secrets:
+- NETBOX_TOKEN: (dein Netbox API Token)
+- NETBOX_URL: https://netbox.pve.mbo-tech-it.de
+```
+
+---
+
+## 📖 Dateien & Funktionen
+
+| Datei | Beschreibung |
+|-------|-------------|
+| `kestra/workflows/backup-provision.yaml` | Hauptworkflow: Netbox→Ansible |
+| `ansible/playbooks/install-borg-client.yaml` | Installation auf Clients |
+| `ansible/playbooks/configure-backup-server.yaml` | Backup-Server Setup |
+| `scripts/borg-backup.sh` | Backup-Ausführung pro Host |
+| `scripts/pre-backup-docker.sh` | Docker-spezifische Dumps |
+| `rclone-sync.service` | S3-Synchronisierung |
+
+---
+
+## 🔒 Security Considerations
+
+1. **SSH-Keys**: Ed25519-Keys für Borg-Zugriff
+   - Private Keys: `/root/.ssh/mbo-backup-key.ed25519` (auf Clients)
+   - Public Keys: `authorized_keys` auf Backup-Server mit `restrict,command=...`
+
+2. **Borg Encryption**: AES256-CTR mit Passphrases
+   - Passphrase sollte in Ansible Vault gespeichert sein
+
+3. **Netbox API Token**: Via Kestra Secrets (nicht im Git!)
+
+4. **Hetzner S3 Credentials**: Via Ansible Vault oder Umgebungsvariablen
+
+---
+
+## 📊 Monitoring & Status
+
+### Backup-Status anzeigen
+
+```bash
+# Auf jedem Client:
+systemctl status mbo-backup.timer
+systemctl list-timers mbo-backup.timer
+
+# Logs:
+journalctl -u mbo-backup -f
+tail -f /var/log/mbo-backup/*.log
+```
+
+### Rclone Sync-Status
+
+```bash
+# Auf Backup-Server:
+systemctl status mbo-rclone-sync.timer
+journalctl -u mbo-rclone-sync -f
+
+# Manuelle Sync:
+sudo -u backup rclone sync --progress /backup/repos hetzner:mbo-backups/production/repos
+```
+
+### Borg Repository Status
+
+```bash
+ssh backup@backup.pve.mbo-tech-it.de
+borg list /backup/repos/SERVER_NAME
+borg info /backup/repos/SERVER_NAME::(latest-backup)
+```
+
+---
+
+## 🔄 Restore-Prozeduren
+
+### Komplettes Restore eines Servers
+
+```bash
+# 1. SSH zum Server
+ssh root@SERVER_NAME
+
+# 2. Hole aktuelles Backup vom Backup-Server
+borg extract --progress \
+  backup@backup.pve.mbo-tech-it.de:/backup/repos/SERVER_NAME::(latest) \
+  /etc
+
+# 3. Oder aus S3 (falls lokal nicht verfügbar)
+rclone ls hetzner:mbo-backups/production/repos/SERVER_NAME/
+```
+
+### Einzelne Datei restoren
+
+```bash
+# Liste Backup-Archive
+borg list backup@backup.pve.mbo-tech-it.de:/backup/repos/SERVER_NAME
+
+# Extrahiere einzelne Datei
+borg extract \
+  backup@backup.pve.mbo-tech-it.de:/backup/repos/SERVER_NAME::archive-name \
+  path/to/file
+```
+
+### Docker Volume restoren
+
+```bash
+# Auf Backup-Server:
+ssh backup@backup.pve.mbo-tech-it.de
+
+# Finde den Export
+ls -la /var/backups/docker/*/
+
+# Entpacke und restore zum Container
+docker run --rm \
+  -v myvolume:/data \
+  -v /var/backups/docker/DUMP:/backup \
+  alpine tar xzf /backup/volume-myvolume.tar.gz -C /data
+```
+
+---
+
+## 🐛 Troubleshooting
+
+### SSH-Fehler beim Backup
+
+```bash
+# Test SSH-Connection:
+ssh -i /root/.ssh/mbo-backup-key.ed25519 \
+  backup@backup.pve.mbo-tech-it.de "echo OK"
+
+# SSH-Keys neu generieren (falls nötig):
+ssh-keygen -t ed25519 -N '' -f /root/.ssh/mbo-backup-key.ed25519
+```
+
+### Borg Repository korrupt
+
+```bash
+# Backup-Server:
+ssh backup@backup.pve.mbo-tech-it.de
+borg check -v /backup/repos/SERVER_NAME
+borg repair /backup/repos/SERVER_NAME
+```
+
+### Rclone S3 Sync läuft nicht
+
+```bash
+# Teste Rclone Connection:
+sudo -u backup rclone listremotes
+sudo -u backup rclone ls hetzner:
+
+# Überprüfe Config:
+sudo -u backup rclone config show hetzner
+
+# Debugging:
+sudo -u backup rclone sync --progress --log-level DEBUG \
+  /backup/repos hetzner:mbo-backups/production/repos
+```
+
+### Kestra Workflow fehlt
+
+```bash
+# Logs in Kestra:
+Settings → Logs → backup-provision
+
+# Manuelle Test:
+curl -X GET https://kestra.pve.mbo-tech-it.de/api/v1/namespaces/automation/flows
+```
+
+---
+
+## 📈 Performance Tuning
+
+### Borg-Kompression
+
+```bash
+# Schneller (weniger CPU): lz4
+# Besser (mehr Dedupe): zstd
+# Im Script anpassen: --compression zstd,10
+```
+
+### Rclone Sync Parallel
+
+```bash
+# In rclone-sync.service:
+rclone sync --progress --transfers 4 --checkers 8 \
+  /backup/repos hetzner:mbo-backups/production/repos
+```
+
+### Backup-Größe reduzieren
+
+```bash
+# Exclude-List in borg-backup.sh erweitern:
+--exclude '*.log'
+--exclude '.cache'
+--exclude 'node_modules'
+```
+
+---
+
+## 📝 Wartung & Cleanup
+
+### Alte Backups prünen
+
+Der borg prune läuft automatisch:
+- Tägliche: 7 Tage
+- Wöchentliche: 4 Wochen
+- Monatliche: 12 Monate
+
+Zu ändern in `borg-backup.sh`:
+
+```bash
+borg prune "$REPO_PATH" \
+  --keep-daily=7 \
+  --keep-weekly=4 \
+  --keep-monthly=12
+```
+
+### Docker-Dumps aufräumen
+
+```bash
+# Manuell (normalerweise automatisch):
+find /var/backups/docker -type d -mtime +7 -exec rm -rf {} \;
+```

+
+## 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.pve.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.pve.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.pve.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.pve.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.pve.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.pve.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.pve.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.pve.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.pve.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.pve.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.pve.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
+```

+  - [ ] Name: `backup-automation`
+  - [ ] Description: "Netbox-integrated Borg backup automation"
+  - [ ] Visibility: Private
+
+## 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

+  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:

+    -H "Content-Type: application/yaml" \
+    -d @kestra/workflows/backup-provision.yaml
+  ```
+- [ ] Secrets in Kestra setzen:
+  - [ ] `NETBOX_TOKEN` = dein API Token
+  - [ ] `NETBOX_URL` = https://netbox.pve.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.pve.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/`
+- ✅ Restore-Test erfolgreich durchgeführt
