How valuable is your data? If your storage drive crashed, would it ruin your day? Your week? Your entire career? Only you can answer those questions for yourself and your organization. But I'll tell you, personally, I need my files -- not only to get my day-to-day job done, but to reference older information and even look at personal keepsakes (like all my digital photos).
Over the years, I've discussed storage strategies a lot. I've talked about the traditional 3-2-1 backup approach, and what I call 3-2-1 off and away backups. I've talked about cloud backup, and how having most of my critical data in the cloud helped me keep going during last year's hurricane evacuation. I've even taken you through an in-depth torture testing of seven different RAID storage devices to find the winners (and losers).
