Buenas, siguiendo a guillotmarc, añadir la que uso yo con la diferencia que no hace falta copiar el gbak sino que lo busca donde este instalado y ya de paso hace una restauracion porque gbak deja una copia comprimida. De paso os mando una funcion para ejecutar programas externos con un poco mas de control sobre la ejecucion.
