I figured I could survive several days without backing up my data before buying a replacement drive.
Well, days turned to weeks and months turned to years, then my main hard drive finally failed.
Then I remembered, “Ah, yes…
I have to buy that second hard drive to back up my data.”
Activating it requires no rocket science.
Just go to the System Preferences and press Time Machine.
However, Time Machine can’t work with MS-DOS (FAT) formatted drives.
As the name suggests, this free backup utility will create a clone of your disk.
By default, CCC will back up everything from the main disk to the chosen destination.
It’s also possible to place the image on the main drive.
This process should also be as painless as possible.
Fortunately, CCC makes the data restoration process as simple as switching the source - target disk.
Too easy to be true, huh?
