This is what is so confusing for me (and I'm sure others). The link to the article above says that:
"
Time Machine is designed to provide automatic “temporal” backup"
As I understood it the main reason why we still needed SuperDuper is because Time Machine does
not make a
bootable backup. However since Apple has updated their Time Machine page it now says:
"
Time Machine copies the entire contents of the computer to your backup drive. It copies every file exactly (without compression), skipping caches and other files that aren’t required to restore your Mac to its original state."
So if it's copying
the entire contents and every file, why wouldn't the backup drive be bootable?
