== OS drive backup conclusion: ==

Once everything is set up the way you like, shut down your system, remove one of the drives, and make a backup. Use a drive of equal or greater size for the backup. This way, if disaster strikes, you can restore your system in no time.

We now have a simple &amp; effective way to know when our operating system drive is about to die on us, so we can take action before anything horrible occurs. Best of all, if you set this up properly, you can have zero downtime &amp; not even have to turn off the machine to get back up and running when a drive fails.
