    What are you transferring the backup from and what to??

     

    We generally advise people now this is overall a bad idea. Start new backups to your new location and preserve your old location for a few months to allow the history to build up in the new backup and ensure nothing is needed from the old one.. once you have used the new one for 3-6months you are unlikely to need the old one again.
