Photo backups. Andrew Marriott Most of us will have more than 4 gigs of photos. Most of us will have more than 4 gigs per shoot! Most photographers will have photo collections that use more than 100's of gigabytes! Many "old" photographers will have terabytes. My collection of digital images, started in about 2000, is currently running at 4.3 terabytes. So how do I back these up? How will you back up your collection? (Before it is too late). Typical duration: 40-50 minutes.
