How to configure a cheap, secure RAID backup system

   <section class="page">

We usually store our photos, documents, and more on a single hard disk—or, increasingly these days, a solid state drive (SSD)—but there’s always the nagging worry that the disk will fail, taking all your work and memories with it. Backing up using Time Machine, Super Duper!, or CrashPlan, say, is a good way of reducing this risk, but there is another: RAID.</p><p>
RAID can be incredibly complicated, but it’s extremely worthwhile—one of the things it can do is to mirror the contents of one disk completely to another, all the time. While cloning your hard disk using Super Duper!, for example, is something that might happen once a day, with a RAID system, every bit of data that’s written to one disk is simultaneously written to the second, so that if one drive fails, you have a perfect copy of everything it contained on the second. (And optionally, if you replace the failed drive, everything will be mirrored back across to it automatically.)</p><p class="jumpTag"><a href="/article/2950478/storage/how-to-configure-a-cheap-secure-raid-backup-system.html#jump">To read this article in full or to leave a comment, please click here[/url]</p></section></article>
