> I have Time Machine set to automatic backup. Do I need a clone backup, too?
No, but....
*** Canned explanation ON ***
There are various approaches to backing up one's drives, each approach "tuned" to addressing different problems that could occur.
I have Time Machine *and* SuperDuper backups.
Time Machine addresses the "oops" problem of accidentally deleting some file or folder of files that it turns out you need, and also the problem of installing something that screws with your system, causing you to want to back up a step or two.
SuperDuper or CCC addresses the problem of the primary hard drive itself failing, allowing you to continue to work until you have a repaired or replaced hard drive in place. Also providing a fall-back for the major system upgrade (which alters MANY files), until you decide you are happy with the new.
Off-site backups address the problems of theft or fire.
I haven't worked out a satisfactory solution to the problem of Global Thermonuclear War.
