 ---
 ### Scenariusz 3: Ransomware / kompromitacja
 **Objawy:**
 - Zaszyfrowane pliki
 - Nieautoryzowane zmiany w bazie
 - Podejrzana aktywność w logach
 **Procedura:**
 1. **NATYCHMIAST** odłącz VM od sieci (Proxmox → VM → Network → Disconnect)
 2. Utwórz snapshot stanu (dla forensics)
 3. Przywróć z offsite backup (PBS):
   ```bash
   scp maciejpi@10.22.68.127:/backup/nordabiz/daily/nordabiz_YYYYMMDD.dump /tmp/
   ```
 4. Utwórz nową VM (nie używaj starej!)
 5. Postępuj zgodnie z [Pełne odtworzenie systemu](#pełne-odtworzenie-systemu)
 6. Zmień wszystkie hasła i klucze API
 7. Zgłoś incydent bezpieczeństwa
 **RTO:** 60-120 minut
 ---
 ### Scenariusz 4: Awaria NPM (Reverse Proxy)
 **Objawy:**
 - ERR_CONNECTION_REFUSED na https://nordabiznes.pl
 - NPM container nie działa
 **Procedura:**
 1. SSH do R11-REVPROXY-01: `ssh maciejpi@10.22.68.250`
 2. Sprawdź container: `docker ps | grep nginx-proxy-manager`
 3. Restart containera: `docker restart nginx-proxy-manager_app_1`
 4. Jeśli nie działa, sprawdź logi: `docker logs nginx-proxy-manager_app_1`
 5. Zweryfikuj konfigurację proxy:
   ```bash
   docker exec nginx-proxy-manager_app_1 sqlite3 /data/database.sqlite \
     "SELECT forward_port FROM proxy_host WHERE id = 27;"
   # Musi być: 5000
   ```
 **RTO:** 5-10 minut
 ---
 ## Procedury odtwarzania
 ### Przywracanie z backupu godzinowego
 ```bash
 # 1. Lista dostępnych backupów
 ls -la /var/backups/nordabiz/hourly/
 # 2. Wybierz backup (np. z godziny 14:00)
 BACKUP_FILE="/var/backups/nordabiz/hourly/nordabiz_20260202_14.dump"
 # 3. Uruchom skrypt restore
 sudo /var/www/nordabiznes/scripts/dr-restore.sh $BACKUP_FILE
 # 4. Weryfikacja
 curl -I http://localhost:5000/health
 ```
 ### Przywracanie z backupu dziennego
 ```bash
 # 1. Lista backupów dziennych
 ls -la /var/backups/nordabiz/daily/
 # 2. Uruchom restore
 sudo /var/www/nordabiznes/scripts/dr-restore.sh /var/backups/nordabiz/daily/nordabiz_20260201.dump
 ```
 ### Przywracanie z offsite (PBS)
 ```bash
 # 1. Skopiuj backup z PBS
 scp maciejpi@10.22.68.127:/backup/nordabiz/daily/nordabiz_20260201.dump /tmp/
 # 2. Uruchom restore
 sudo /var/www/nordabiznes/scripts/dr-restore.sh /tmp/nordabiz_20260201.dump
 ```
 ### Pełne odtworzenie systemu
 Wykonaj gdy VM jest całkowicie niedostępna lub skompromitowana.
 #### Krok 1: Przygotowanie nowej VM
 ```bash
 # Na Proxmox - utwórz VM:
 # - ID: 249 (lub nowy)
 # - CPU: 4 vCPU
 # - RAM: 8 GB
 # - Disk: 100 GB SSD
 # - Network: vmbr0
 # - IP: 10.22.68.249/24
 # - Gateway: 10.22.68.1
 # - OS: Ubuntu 22.04 LTS
 ```
 #### Krok 2: Instalacja pakietów
 ```bash
 sudo apt update && sudo apt upgrade -y
 sudo apt install -y python3 python3-venv python3-pip postgresql-14 git nginx rsync
 ```
 #### Krok 3: Konfiguracja PostgreSQL
 ```bash
 sudo -u postgres createuser nordabiz_app
 sudo -u postgres createdb nordabiz -O nordabiz_app
 sudo -u postgres psql -c "ALTER USER nordabiz_app WITH PASSWORD 'NOWE_HASLO';"
 ```
 #### Krok 4: Przywrócenie bazy z backup
 ```bash
 # Skopiuj backup z PBS
 scp maciejpi@10.22.68.127:/backup/nordabiz/daily/nordabiz_LATEST.dump /tmp/
 # Restore
 sudo -u postgres pg_restore -d nordabiz -O --role=nordabiz_app /tmp/nordabiz_LATEST.dump
 # Nadaj uprawnienia
 sudo -u postgres psql -d nordabiz -c "GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO nordabiz_app;"
 sudo -u postgres psql -d nordabiz -c "GRANT ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA public TO nordabiz_app;"
 ```
 #### Krok 5: Instalacja aplikacji
 ```bash
 sudo mkdir -p /var/www/nordabiznes
 sudo chown www-data:www-data /var/www/nordabiznes
 # Clone z Gitea
 sudo -u www-data git clone https://10.22.68.180:3000/maciejpi/nordabiz.git /var/www/nordabiznes
 # Virtualenv
 cd /var/www/nordabiznes
 sudo -u www-data python3 -m venv venv
 sudo -u www-data venv/bin/pip install -r requirements.txt
 ```
 #### Krok 6: Przywrócenie konfiguracji
 ```bash
 # Skopiuj .env z backup
 scp maciejpi@10.22.68.127:/backup/nordabiz/config/latest/.env /var/www/nordabiznes/.env
 sudo chown www-data:www-data /var/www/nordabiznes/.env
 sudo chmod 600 /var/www/nordabiznes/.env
 # WAŻNE: Zaktualizuj DATABASE_URL w .env jeśli zmieniłeś hasło!
 ```
 #### Krok 7: Konfiguracja systemd
 ```bash
 sudo cp /var/www/nordabiznes/docs/nordabiznes.service /etc/systemd/system/
 sudo systemctl daemon-reload
 sudo systemctl enable nordabiznes
 sudo systemctl start nordabiznes
 ```
 #### Krok 8: Weryfikacja
 ```bash
 # Status usługi
 sudo systemctl status nordabiznes
 # Health check
 curl -I http://localhost:5000/health
 # Logi
 sudo journalctl -u nordabiznes -f
 ```
 #### Krok 9: Aktualizacja NPM (jeśli zmieniono IP)
 Jeśli nowa VM ma inny IP, zaktualizuj NPM:
 ```bash
 ssh maciejpi@10.22.68.250

 ## Testy DR
 ### Test kwartalny
 Wykonuj co kwartał:
 1. **Przygotowanie:**
   - Utwórz testową VM w Proxmox
   - Skopiuj backup z PBS
 2. **Wykonanie:**

 # Konfiguracja Offsite Backup do PBS
 **Status:** Wymaga ręcznej konfiguracji SSH
 **Data:** 2026-02-02
 ## Klucz SSH do dodania na PBS
 Klucz publiczny z NORDABIZ-01 (10.22.68.249):
 ```
 ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIHHpPjhwjOUBTmo0MFus4QsgAlI5JxbPNlhW0aPV7vIg maciejpi@NORDABIZ-01
 ```
 ## Instrukcja konfiguracji
 ### Krok 1: Dodanie klucza na PBS (10.22.68.127)
 Zaloguj się na PBS przez konsolę Proxmox lub inną metodę i wykonaj:
 ```bash
 # Na PBS (10.22.68.127)
 mkdir -p /home/maciejpi/.ssh
 echo "ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIHHpPjhwjOUBTmo0MFus4QsgAlI5JxbPNlhW0aPV7vIg maciejpi@NORDABIZ-01" >> /home/maciejpi/.ssh/authorized_keys
 chmod 700 /home/maciejpi/.ssh
 chmod 600 /home/maciejpi/.ssh/authorized_keys
 chown -R maciejpi:maciejpi /home/maciejpi/.ssh
 ```
 ### Krok 2: Utworzenie katalogów backup na PBS
 ```bash
 # Na PBS (10.22.68.127)
 sudo mkdir -p /backup/nordabiz/{daily,config}
 sudo chown -R maciejpi:maciejpi /backup/nordabiz
 ```
 ### Krok 3: Weryfikacja połączenia z NORDABIZ-01
 ```bash
 # Na NORDABIZ-01 (10.22.68.249)
 ssh maciejpi@10.22.68.127 "echo OK"
 ```
 ### Krok 4: Dodanie cron offsite
 Po weryfikacji połączenia, utwórz plik cron:
 ```bash
 # Na NORDABIZ-01
 sudo tee /etc/cron.d/nordabiz-offsite << 'EOF'
 # NordaBiz Offsite Backup
 SHELL=/bin/bash
 PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
 # Sync daily backups do PBS o 4:00
 0 4 * * * root rsync -avz --delete /var/backups/nordabiz/daily/ maciejpi@10.22.68.127:/backup/nordabiz/daily/ 2>> /var/log/nordabiznes/backup.log
 # Sync config do PBS o 4:30
 30 4 * * * root rsync -avz /var/backups/nordabiz/config/ maciejpi@10.22.68.127:/backup/nordabiz/config/ 2>> /var/log/nordabiznes/backup.log
 EOF
 sudo chmod 644 /etc/cron.d/nordabiz-offsite
 ```
 ### Krok 5: Test synchronizacji
 ```bash
 # Na NORDABIZ-01
 rsync -avz --dry-run /var/backups/nordabiz/daily/ maciejpi@10.22.68.127:/backup/nordabiz/daily/
 ```
 ## Alternatywny serwer offsite
 Jeśli PBS jest niedostępny, można użyć r11-git-inpi (10.22.68.180) jako alternatywy:
 ```bash
 # Zmień IP w cron na 10.22.68.180
 # Dodaj klucz SSH do Gitea server
 ```
 ## Weryfikacja
 ```bash
 # Sprawdź backupy na PBS
 ssh maciejpi@10.22.68.127 "ls -la /backup/nordabiz/daily/"
 # Sprawdź logi
 ssh maciejpi@10.22.68.249 "tail -20 /var/log/nordabiznes/backup.log"
 ```
