I moved my huge iphoto library to My Passport for Mac. I would now like to make sure I have a backup of this. What is the best way to do this?
You will need a second drive or other media so you have 2 copies.
Pretty much what Joe_S said.
It’s sad sp many people move data to an external drive to free up space as the only copy and think that is a backup.
I use ChronoSync ( http://www.econtechnologies.com/chronosync/overview.html)) for my photos backup. I have a weekly schedule set up (you can set it at any interval but weekly works for me) so that I can sync any new photos that I have in my source folders. I basically have set it and forgotten it.
