You know you should be backing up, right? And still, the dirty little secret of modern computing is that most of us--Mac|Life staff included--don’t back up as much as we should, and in some cases, not at all. And even if you do back up, using that old drive you purchased in a fit of Y2K preparations isn’t much protection. Drives fail, and it’s always a question of when, not if. Data Robotics, the makers of the Drobo, hope to make rock-solid backup simple and foolproof with their line of external drive enclosures.
