backup de postgree desde java

[rglk666]

A mi me funciona asi:

Código:

try{    
	        ProcessBuilder pb;    
	        Process p;    
	        pb = new ProcessBuilder("C:/Archivos de programa/PostgreSQL/9.1/bin/pg_dump.exe ", "-i", "-h", 
	        "localhost", "-p", "5432","-U", "postgres", "-F", "c", "-b", "-v" ,"-f", 
	        "C:\\Documents and Settings\\Usuario\\Escritorio\\copia.backup",
	        "NombreBaseDeDatos");    
	        pb.environment().put("PGPASSWORD", "123456");    
	        pb.redirectErrorStream(true);    
	        p = pb.start();     
        }catch(Exception ex){    
            JOptionPane.showMessageDialog(null, ex);    
        }

Solo cambias los parámetros obviamente.
