If you back up a file with encryption key xxxxxx, subsequently change the key at a later date, then when you try to restore the file, you will be prompted to enter the correct encryption key (xxxxxx). If you do not know the correct key, then you will not be able to restore or retrieve the data. THERE IS NO "BACK DOOR". So be careful about changing encryption keys, as it is up to you to manage and track them.
