```
## 🚀 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 {} \;
```

# 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.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
```

# Setup-Checkliste für Backup-Automation
## Phase 1: Vorbereitung (einmalig)
- [ ] Backup-Server VM unter Proxmox erstellen
- [ ] 2+ CPUs
- [ ] 4+ GB RAM
- [ ] Großes Datenvolume (/backup mit genug Platz)
- [ ] Hostname: `backup.pve.mbo-tech-it.de`
- [ ] Hetzner S3 Credentials besorgen
- [ ] Access Key ID
- [ ] Secret Access Key
- [ ] Endpoint
- [ ] Bucket Name: `mbo-backups`
- [ ] Netbox API Token generieren
- [ ] Admin → Users → Create Token
- [ ] Token kopieren und sicher speichern
- [ ] Git-Repository erstellen in Gitea
- [ ] 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
- [ ] 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.pve.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.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
