I used to clone a backup regularly using Carbon Copy Cloner from Mike Bombich, however, when Disk Utility started to encompass the same capability natively (using the "Restore" feature) I haven't gone third party to make a clone for a REALLY long time.
Could you elaborate on how/where Disk Utility does a clone. Under 10.11.x a quick look at Disk Utility does not show anything along these lines. Thanks.
