## 🚨 **BACKUP & RECOVERY**

### **Critical Data Locations:**
```bash
# BTCPay Database
/var/lib/docker/volumes/generated_postgres_*

# Bitcoin Wallet & Settings  
/var/lib/docker/volumes/generated_bitcoin_*

# Tor Hidden Service Keys
/var/lib/docker/volumes/generated_tor_*

# Configuration Files
/opt/.env

```

### **Backup Command:**
```bash
sudo tar -czf btcpay-backup-$(date +%Y%m%d).tar.gz \
  /var/lib/docker/volumes/generated_* \
  /opt/.env \
  /opt/btcpayserver-docker/ \
  /home/sysadmin/mattermost-webhook/
```

### **Restore Process:**

sudo btcpay-down.sh
sudo tar -xzf btcpay-backup-YYYYMMDD.tar.gz -C /
sudo btcpay-up.sh
cd ~/mattermost-webhook && npm start
```

## 📞 **TROUBLESHOOTING**

### **Common Issues:**

**1. Webhook SSL Error in Mattermost:**
```bash
# Solution: Use SSH tunnel
ssh -N -L 3001:localhost:3001 -p 2255 -i vps_hardening_key sysadmin@thebankofdebbie.giize.com &

# Then configure Mattermost webhook URL as: http://localhost:3001/webhook/btcpay
```

**2. Bitcoin Sync Slow:**
```bash
# Normal over Tor - check progress:
docker logs btcpayserver_bitcoind | tail -20
```

**3. Onion Services Not Accessible:**
```bash
# Restart Tor containers:
docker restart tor tor-gen
# Wait 5 minutes for new addresses
```

**4. Storage Issues:**
```bash
# Check Bitcoin pruning is working:
docker logs btcpayserver_bitcoind | grep -i prune
# Should show: "Prune configured to target 10000 MiB"
```
