Cloud or Local Backup is perfect for files that go missing or get corrupted, but when your hard drive dies, you’ll need a clone. Don’t worry, Dolly’s got you covered! Here’s how to clone your drive in case of disaster, and how to get back up and running in less that two minutes.
What is a Clone?
A clone contains much more than your data. It’s an exact copy of your entire hard drive. So exact that all you need to do is plug it into your Mac and Restart, and you’ll be able to pick up right where you left off.
It sounds complicated, but Clone makes creating a clone, and keeping it up-to-date a simple process.
To clone your Mac, you’ll need a second drive. A second internal drive in a Mac Pro will do, but iMac and MacBook users will need an external drive. Your clone will need to be at least as large as your Mac’s startup drive.
Format Your Drive
If you’ve got a drive that’s already formatted for Mac, skip to the next step. But if you’re using a drive formatted for Windows or another operating system, you’ll need to re-format the drive before you can use it with Dolly Clone.
Formatting your drive will erase everything on it.
If you’re re-using a drive, make sure you copy any important data to another location. This would be a great time to use Space (section 1.3) to store the contents of your drive in the cloud for safekeeping.
Open Disk Utility, located in Applications > Utilities. Connect your drive, and select it in the left-hand column. In the tabs at the top of the window, select Erase and choose Mac OS Extended (Case-sensitive, Journaled) in the Format pull-down menu.
Type a name for your clone drive in the Name field, and click Erase… Click Erase again in the pop-up window.
Congratulations! You’re ready to use Clone.
Your First Clone
From Dolly’s Status Bar, choose Clone.
Make sure your Mac-formatted destination drive is connected, and click Start New Clone.
In the next pop-up pane, select your source drive. This is the drive that you would like to clone. Click Next.
Select your destination drive. This is the secondary drive that will contain your clone. Click Clone.
The cloning process will erase everything on your destination drive. As a precaution, DollyDrive will pop up a confimation pane. Click Continue to begin cloning, or Abort to cancel.
A Finder window will pop up to confirm your choice to erase the destination disk and clone your drive. Enter the password for your user account (the one you use when you start your Mac) and click OK.
DollyDrive will begin cloning your Mac. If you need to halt a Cone, use the Stop button. When your clone is finished, DollyDrive will display a message showing the date and time of your completed clone.
Updating an Existing Clone
Updating a clone is just as simple as creating a new one. Plug in the destination for your clone, and choose Update Clone in the Clone section of the Status Bar. Updating an existing clone is a much faster process than starting from scratch. DollyDrive will scan your clone, and update only the files that have changed since last time your drive was cloned.
Booting From a Clone
If you ever need to use your clone, you can start your Mac with it by plugging in your clone drive, and restarting your Mac. Hold down the Option key, which will bring up the Startup Manager, where you can select your clone to boot your Mac.
