+# MongoDB Backup & Restore Scripts
+
+Kompletní řešení pro zálohování a obnovu MongoDB databází na Unraid.
+
+## 📋 Obsah backup
+
+Skripty zálohují a obnovují **KOMPLETNĚ VŠECHNO**:
+- ✅ **Všechny databáze** (včetně `admin` pro credentials a roles)
+- ✅ **Všechny kolekce** a dokumenty (BSON formát)
+- ✅ **Všechny indexy** (včetně unique, compound, text indexů)
+- ✅ **Metadata kolekcí** (validators, options, atd.)
+- ✅ **Uživatele a role** (v admin DB)
+- ✅ **Komprimace gzipem** pro úsporu místa
+
+**Oveřeno zachowáno:**
+- Indexové struktury se zachovávají identicky
+- Collection validators (JSONSchema) se zachovávají
+- Collection options (capped collections, atd.) se zachovávají
+- Všechny system collections (`system.indexes`, `system.users`, atd.)
+- Opaque object IDs, binary data, všechny BSON typy
+
+## 🔄 Použití
+
+### 1. **Backup skript** (`mongodbbackup_with_gzip.sh`)
+
+Zálohuje všechny DB do `/mnt/user/Backup/Critical/MongoDBBackup/tower/{DB_NAME}/{YYYY-MM-DD_HHMM}/`
+
+```bash
+chmod +x mongodbbackup_with_gzip.sh
+./mongodbbackup_with_gzip.sh
+```
+
+**Přidej do Unraid scheduled tasksu:**
+```
+Schedule: Daily (nebo jak chceš)
+Command: /mnt/user/path/mongodbbackup_with_gzip.sh
+```
+
+**Struktura záloh:**
+```
+/mnt/user/Backup/Critical/MongoDBBackup/tower/
+├── admin/
+│   └── 2026-05-23_1530/
+│       ├── admin.archive.gz
+│       └── admin.err (jen pokud je chyba)
+├── fio/
+│   └── 2026-05-23_1530/
+│       ├── fio.archive.gz
+│       └── ...
+└── ...
+```
+
+**Konfigurace:**
+- `CONTAINER_NAME` - jméno MongoDB kontejneru
+- `KEEP_DAYS` - Jak dlouho se uchovávají staré zálohy (default: 3 dny)
+- `WHAT_TO_BACKUP` - Seznam DB k zálohování
+
+---
+
+### 2. **Restore skript** (`mongodbrestore_from_backup.sh`)
+
+Obnovuje všechny DB ze zálohy na LOCAL MongoDB.
+
+```bash
+chmod +x mongodbrestore_from_backup.sh
+./mongodbrestore_from_backup.sh /mnt/user/Backup/Critical/MongoDBBackup/tower
+```
+
+**Co skript dělá:**
+1. ✅ Najde nejnovější backup pro KAŽDOU DB
+2. ✅ Extrahuje .tar.gz archiv
+3. ✅ Obnoví do MongoDB (s `--drop` na přepsání existujících)
+4. ✅ Validuje úspěch
+5. ✅ Čistí temp soubory
+
+---
+
+### 3. **Ověřovací skript** (`verify_backup_integrity.sh`)
+
+Kontroluje že se VŠECHNO správně obnovilo (indexy, metadata, kolekce).
+
+```bash
+chmod +x verify_backup_integrity.sh
+./verify_backup_integrity.sh
+```
+
+**Co skript ověřuje:**
+1. ✅ Zda všechny DB existují
+2. ✅ Počet a jména kolekcí
+3. ✅ Indexy pro každou kolekci (včetně jejich definic)
+4. ✅ Počet dokumentů v každé kolekci
+5. ✅ Velikost dat v MB
+6. ✅ Uživatele a role (admin DB)
+
+**Příklad výstupu:**
+```
+Verifying database: fio
+✅ Database exists: fio
+✅ Collections count: 8
+   Collections:
+     - users
+     - products
+     - logs
+   Indexes per collection:
+     fio.users: 3 indexes
+       - { "_id": 1 }
+       - { "email": 1 }
+       - { "created_at": -1 }
+   Collection stats:
+     users:
+       Documents: 12345
+       Size: 45.23 MB
+```
+
+---
+
+## 🧪 Testování na 2 Unraid serverech
+
+### Scénář: Tower1 → Tower2 (Kompletní test)
+
+#### **Krok 1: Na Tower1 (zdroj) - Spusť backup:**
+```bash
+/mnt/user/Backup/Critical/MongoDBBackup/mongodbbackup_with_gzip.sh
+
+# Ověř že backup existuje
+ls -lh /mnt/user/Backup/Critical/MongoDBBackup/tower/*/*/
+```
+
+**Očekávaný výstup:**
+```
+/mnt/user/Backup/Critical/MongoDBBackup/tower/
+├── admin/2026-05-23_1530/admin.archive.gz (234K)
+├── fio/2026-05-23_1530/fio.archive.gz (45M)
+├── torrents/2026-05-23_1530/torrents.archive.gz (...
+└── ...
+```
+
+#### **Krok 2: Zkopíruj backup do Tower2:**
+```bash
+# Přes SMB share / rsync / fyzicky disku
+# Zkopíruj celou strukturu: /mnt/user/Backup/Critical/MongoDBBackup/tower/
+```
+
+#### **Krok 3: Na Tower2 (cíl) - Obnovte zálohu:**
+```bash
+/mnt/user/Backup/Critical/MongoDBBackup/mongodbrestore_from_backup.sh /mnt/user/Backup/Critical/MongoDBBackup/tower
+
+# Výstup by měl být:
+# SUCCESS: admin restored successfully
+# SUCCESS: fio restored successfully
+# ...
+```
+
+#### **Krok 4: Ověř INTEGRITU na Tower2 - Nejdůležitější!**
+```bash
+/mnt/user/Backup/Critical/MongoDBBackup/verify_backup_integrity.sh
+```
+
+**To by mělo ověřit:**
+- ✅ Všechny DB existují
+- ✅ Všechny kolekce se obnovily
+- ✅ Všechny indexy jsou tam (se stejnými definicemi!)
+- ✅ Počet dokumentů je identický
+- ✅ Uživatelé a role jsou obnovení
+
+#### **Krok 5: Manuální spot-check (volitelně):**
+```bash
+docker exec -it MongoDB mongosh --host localhost --port 27017
+
+# Ověř indexy v konkrétní kolekci
+use fio
+db.some_collection.getIndexes()  # Měly by být stejné jako na Tower1
+
+# Ověř počet dokumentů
+db.some_collection.countDocuments()  # Měl by být identický
+
+# Ověř že data jsou bezpečná
+db.some_collection.findOne()
+```
+
+---
+
+## ⚠️ Důležité poznámky
+
+1. **`--drop` flag** - Restore skript obnovuje s `--drop`, což PŘEPÍŠE existující databázi. To je zvláště důležité pro test.
+
+2. **Admin DB** - Obsahuje uživatele a role. Pokud máš auth, musíš je správně obnovit.
+
+3. **Čištění** - Po úspěšném testu si můžeš vymazat temp soubory:
+   ```bash
+   rm -rf /tmp/mongodb_restore_*
+   ```
+
+4. **Disk space** - Při restore se vytváří tmp soubory. Ověř prostor na `/tmp` (nebo `/mnt/user`).
+
+5. **MongoDB port** - Oba skripty očekávají MongoDB na `localhost:27017` (default).
+

+
+---
+
+## 🔧 Troubleshooting
+
+| Problém | Řešení |
+|---------|--------|
+| `ERROR: Container not found` | Ověř jméno kontejneru v `CONTAINER_NAME` |
+| `Dump file too small` | Ověř že MongoDB běží a má data |
+| `mongodump: command not found` | Mongodump by měl být v MongoDB image, zkontroluj Docker image |
+| `Permission denied` | Ověř práva na složky: `chmod 755 /mnt/user/Backup/Critical/MongoDBBackup` |
+
+---
+
+## 📝 Tipy
+
+- **Archivuj staré zálohy** - Pokud chceš uchovávat dlouhodobější zálohy, zkopíruj složky před KEEP_DAYS expirací
+- **Ověř čitelnost** - Po backup jdi ověřit že soubor lze extrahovat: `tar -tzf admin.archive.gz | head`
+- **Monitoruj velikost** - `du -sh /mnt/user/Backup/Critical/MongoDBBackup/` - kontroluj disk space
