How-To Copy Time Machine to New Drive

By | 2010/09/28

How can I copy my existing Time Machine backup over to a new, larger drive?

The easiest way is to just use Disk Utility in OS X!


Tip: Be sure to first format (Erase) your new drive as Mac OS Extended Journaled!

– First, turn OFF Time Machine in your System Preferences before beginning.

– Then with both drives connected, locate and click on the Restore tab in Disk Utility.

– Next, simply drag your old existing Time Machine to the Source and your new drive as the Destination. I also suggest checking ‘Erase Destination’.

Then click to Restore and wait several hours depending on the size of your existing backup.

Sweet!
