			        	File BackupDir = new File(sd, "별메모장/");
			        	BackupDir.mkdir();

			            File currentDB = new File(data, "//data//project.star_note//databases//Star_DB.db");

			            FileChannel src = new FileInputStream(currentDB).getChannel();
			            FileChannel dst = new FileOutputStream(backupDB).getChannel();
			            dst.transferFrom(src, 0, src.size());
			            src.close();
