Apple’s Time Machine makes it easy to restore from a catastrophic drive failure, and also gives you a way to restore deleted files or older versions of files you’ve been working on. The vast majority of us using Time Machine have a regular hard drive to back up to.
We all know that hard drives fail, unfortunately. What can you do? One solution is to rotate your backup disks. (Another, of course, is to use a cloud backup service like Backblaze.)
Time Machine handles multiple drives pretty easily, but just in case you’re confused about how to do it, I recently posted this step-by-step guide to help walk you through the process.
