+====== PostgreSQL mentés és helyreállítás ======
-==== WAL archiválás (primary) ====
+==== Előkészítő műveletek ====
+A mentés és helyreállítás gyakorlásához szükség van egy telepített és inicializált PostgreSQL adatbázis példányra. Mentések a pg01 (192.168.100.71) gépről készülnek. Helyreállításhoz a pg03 (192.168.100.73) gépet használjuk. A hozzáférések ''trust'' típusú hozzáférések, a gépek jelszó nélkül érik el egymást.
