I am often asked if I have a backup of my Mac. And unfortunately for the person asking the question, I’m a little like the watchmaker who, when you ask him what time it is, he tells you how to make a watch. First the answer is definitely, “yes!”Gentle Souls Women's Dana Slip Heart Topline Ballet Flat B074CJ4T4B 7.5 M US|RoseStuart Weitzman Women's Evon Ballet Flat B074T6Y625 12 B(M) US|Ballet Luxe Suede In fact, I have 3 local backups of sorts.
I contend that you must have at least two different local backups, for two likely events:
- For the event that your hard drive fails and gets replaced.Propet Women's Washable Walker Sneaker B019S1FKQU 8.5 W US|Bronze
- For the event that your Mac fails and you decide to replace it.Skechers Performance Women's Go Walk 4 Propel Walking Shoe B01IIZC9OS 7.5 B(M) US|Taupe
And if you have the two backups that I suggest below, you can recover from either event in just a few minutes to an hour or so.
So if you haven’t already, purchase two external hard drives. Propet Women's TravelActiv Zip Walking Shoe B01IODDOJI 5.5 B(M) US|Silver, LimeThey should be the same storage capacity as the drive that you are backing up. I like the Lacie Thunderbolt drives for this purpose. But you may like another drive better, and that’s just fine. As long as the drives are reliable, your data will be safely stored for the day that disaster comes.
So without belaboring the point, I will tell you what my two backup systems and my bonus backup (my 3rd local backup).
- SuperDuper! – hard drive clone.
- Time Machine – Apple’s built-in backup system.

SuperDuper! is software that creates an exact bootable clone of your hard drive. You can find it at the Skechers Women's Go Walk Joy-15612 Sneaker B07535PV66 11 B(M) US|Black site. Let me tell you how this averted disaster for me on at least two occasions.

A few years back, I had an iMac that began failing after running for an hour or so. For a few days, the time to failure got a little shorter. I had a backup, but wasn’t looking forward to putting everything back on a new hard drive. I knew that cloning a drive was theoretically possible, but I had never put it to the test.
I began by searching for software that would make an exact, bootable copy of the hard drive. Alegria Women's Classic Clog B01C6ILU16 39 M EU / 9-9.5 B(M) US|Tar TooledMy research turned up SuperDuper! I figured out that if I let the computer power down and cool off, it would run long enough to finish the cloning of the drive. That was fortunate, and not usually the way things work out.
I purchased an internal hard drive and connected it with an adapter that turns an internal drive into an external drive. Bonus:Salomon Women's Crossamphibian Swift W Athletic Sandal B01HD2ST7I 5 B(M) US|Deep Peacock Blue. Nice.
Using SuperDuper!, I cloned the drive. When the clone finished, I rebooted the iMac and caused it to boot from the external drive.Propet Stability Walker B005GV3S5M 10 C/D US|Black Leather To my amazement, although much slower than the internal hard drive, the computer booted up and I saw my desktop screen exactly as I expected. Every icon in place.Vionic Women's Satima Walking Shoes B018VLTE42 7.5 B(M) US|Black I tried a few programs to convince myself that I had indeed cloned the drive. All of my little tests worked perfectly.
To finish the job, I found an explanation of how to replace the internal iMac drive on YouTube. I removed the failing drive from my iMac and put the cloned in its place. I closed everything up and powered up.
The iMac was working exactly as before the change, only better. The hard drive was faster and had a higher capacity. Win win.

This case, rather recently, made me glad that I follow my own rules of backing everything up (twice) before applying an OS X update. In this case, I was updating to El Capitan (OS X 10.11), so I made my usual SuperDuper! clone, as well as the Time Machine backup.
Upon installing the update, I got the spinning color wheel. After several attempts to restart the process, it stayed spinning over night. I made an appointment for the local Apple Genius Bar, hopefully they could help my finish the update.
They had never heard of a Retina Macbook Pro SSD drive failing–until that day. Apparently, by downloading the update,Water Shoes for Womens and Mens Summer Barefoot Shoes Quick Dry Aqua Socks for Beach Swim Yoga Exercise B07CZVD62H XL (Women:10.5-11.5/Men:9-9.5)|Patchwork/Blue the drive accessed an area that had not previously been accessed. And so I was caught in a loop. The update had gotten to that spot where the old OS was no longer available,HOKA ONE ONE Women's Stinson 3 ATR Trail Running Shoe B01H6A89S6 5.5 B(M) US|Black but the new OS had not been fully installed.
The Apple Genius asked if I had a backup. I smiled and simply said yes. I wanted to tell him all about my various backup procedures, but I refrained.
So, the procedure at this point was to replace the SSD drive. PUMA Women's Fierce Krm Cross-Trainer Shoe B01KX1BV4O 10.5 M US|Dawn/Puma WhiteWhen asked if I wanted them to restore from a backup, I declined. I knew that I might have better results with my SuperDuper! backup than with the Time Machine backup.
In this instance, where only the hard drive is being replaced, SuperDuper! is by far the easiest recovery. I followed the instructions on the Shirt-Pocket website:
- Boot from the external drive (a clone of my hard drive)
- Open SuperDuper! and tell it to restore everything
- Wait until SuperDuper! is done and quit.
- Shut down the computer
- Remove the external drive
- Boot the computer as normal
As I had experienced previously, everything came back exactly as it had been before the failure. I then updated to El Capitan without incident. I’m writing this post from that computer.

In this case, the hard drive may or may not have failed,Muck Boot Womens Wetland Boot B0083IAAPQ 8 M US|Bark but some other vital component has failed, and the best option is to replace the computer. Here’s where Time Machine really shines. Time Machine brings a new computer as close to the same as your old computer as it possibly can.
In the case of a new computer, you probably don’t want a clone of the drive!

What was the third backup (of sorts) mentioned earlier? That’s the sync between my main computer and my travel computer.Hi-Tec Women's Equilibrio Bijou Mid I-W Hiking Shoe B01A0FGE7C 7.5 B(M) US|Black/Forget Me NotThat’s the topic of another post.
