I've got MAC OS X 10.6 Snow Leopard. I'm trying to backup to an external harddrive using time machine, everything is set, and ready, but it never backs up. even when I click back up now, it still doesn't backup, it doesn't give me any errors. the icon on the menu bar just rotates then stops, and nothing happens.
Please help and advise. Feel free to ask if you need me to clarify anything
Thanks for your time
