Add A Clone Partition to Your Backup DriveIn case you missed it, March 31st was World Backup Day, a big topic of discussion on the last few Talkcasts, which culminated in a visit by the team at Dolly Drive.

Inspired by the conversation, I wanted to create a clone-sized partition to mirror my SSD. I had an extra external drive on my desk but, like most, it already had some important data on it. In this video I will show you how to add a partition to an existing drive so it can be repurposed to make a clone of your boot drive.

I'll be using Dolly Drive Revo, a free Dolly Drive 10 GB Account and Disk Utility in Mountain Lion. The actual cloning can also be done with Carbon Copy Cloner or Super Duper! if you prefer.

Warning: Before you attempt any disc-related modifications, please be sure to have a backup of the data contained on that drive.
