+# PostgreSQL Backup - Tower
+
+PostgreSQL 18 (Docker: `postgresql18`) na Tower (192.168.1.76).
+
+## Konfigurace
+
+| Parametr | Hodnota |
+|----------|---------|
+| Server | Tower (192.168.1.76) |
+| Container | `postgresql18` |
+| Port | 5432 |
+| User | `vladimir.buzalka` |
+| Metoda | `pg_dumpall` (všechny DB najednou) |
+| Záloha | `/mnt/user/Backup/Critical/PostgreSQLBackup/tower/YYYY-MM-DD_HHMM/` |
+| Retence | 7 dní / posledních 7 záloh |
+
+## Skripty
+
+### `postgresqlbackup_with_gzip.sh`
+Provede `pg_dumpall` všech databází, rolí a tablespaces. Výstup je komprimovaný gzip soubor `all_databases.sql.gz`.
+
+```bash
+bash postgresqlbackup_with_gzip.sh
+```
+
+Výsledná struktura:
+```
+/mnt/user/Backup/Critical/PostgreSQLBackup/tower/
+└── 2026-05-23_0200/
+    └── all_databases.sql.gz
+```
+
+### `postgresqlrestore_from_backup.sh`
+Obnoví všechny databáze z nejnovější zálohy (nebo ze zadané cesty).
+
+```bash
+# Nejnovější záloha (automaticky)
+bash postgresqlrestore_from_backup.sh
+
+# Konkrétní záloha
+bash postgresqlrestore_from_backup.sh /mnt/user/Backup/Critical/PostgreSQLBackup/tower/2026-05-23_0200
+```
+
+> **POZOR:** Dump obsahuje `--clean --if-exists`, takže restore přepíše existující data.
+
+### `verify_backup_integrity.sh`
+Ověří po restore že jsou všechny DB, tabulky, indexy a role přítomny a funkční.
+
+```bash
+bash verify_backup_integrity.sh
+```
+
+## Nastavení Unraid User Script
+
+Na Tower přidat User Script `POSTGRESQL_BACKUP`:
+
+```bash
+#!/bin/bash
+bash /boot/config/plugins/user.scripts/scripts/POSTGRESQL_BACKUP/postgresqlbackup_with_gzip.sh
+```
+
+Schedule: **Daily**
+
+## Windows přístup k zálohám
+
