From the Last To Know This™ Dept: Clone using USB Boot Installer
Posted by: MrNoBody

Why didn't anyone tell me you could do this??

Honestly did not know you could boot from a 'Install macOS...' USB stick, use
Restore with Time Machine back-up to a new external USB drive and have a perfect
clone of a boot drive.
On cMP running Mojave:
  • Plug empty SSD external (Target) into USB 3.1 port
  • Plug USB Installer into a USB2 port & choose it as Startup Disk
  • Restart
  • Choose 'Restore From Time Machine Backup' in the Utilities menu
  • Choose the desired TM backup source & Restore.
  • Take a walk or a nap
  • DONE! A bootable, full clone of my startup drive.

Well, I didn't know one could clone from an installer but then again I'm not a geek. But I did clone an external drive from that window...

That's not a clone.

It's restoring from Time Machine backup onto an external drive.

...But yeah, that can be useful, too.

Absolutely not!

I was at the range blowing thru a small fortune in ammo with a FN Five-seven ODG!

I'm still a bit confused. If it's not a clone (meaning an exact copy of everything on ones HD, including OS and all docs and settings), is it just the OS?

I get this step— Plug empty SSD external
What is this? — Plug USB Installer

I was under the impression that creating a clone from a TM backup takes a LOT longer than doing the same thing via the free version of SuperDuper (which only creates full clones, not incremental updating a backup...)

No; it is a full, bootable copy of my boot drive w/ all Users, Apps, Documents, Settings, etc.
Only thing different I've identified is the device's UUID.
If clone isn't the proper term, then maybe duplicate would be acceptable?

What is this? — Plug USB Installer:
a bootable "Install macOS Mojave" USB Flash Drive [support.apple.com]

iirc, the whole job took < 40 minutes including three reboots. Don't recall if
SuperDuper was any faster. (cMP 5.1 12-core 48GB RAM)

In the jargon, it's neither a "clone," nor a "duplicate."

It's a new OS install with restore from Time Machine.

A clone is as good a copy as you can get without doing a bit-copy. It's a 1:1 copy of the contents of the drive, minus some irrelevant caches.

A restore from Time Machine involves installing a new OS -- which can consist of very different files than what you had originally -- and then settings, support files and user-data are migrated to the new system from the backup.

Seems like a classic clone can contain whatever errors that have developed in ones OS, whereas this method has a factory fresh OS with the latest Time Machine of ones stuff.

They both have this liability. When you restore by Time Machine, you can re-introduce issues from plist files and LaunchAgents and such.

Of note: You can run the Migration Assistant to migrate date from a clone as easily as you can restore from a Time Machine backup.

It's advantageous to have multiple backups. I highly recommend having both a Time Machine backup and a nightly-updated clone.

A Time Machine backup allows you to recover old versions of your files and the frequency of the backups often permits you to restore a file you just accidentally deleted.

If your boot drive fails, you can boot from a clone and be up and running immediately just as you were as of the last backup, while booting from a Time Machine drive leaves you only with Apple's Recovery options (erase or repair, reinstall the OS and restore from a backup).

Technically not a 'clone' because it's not a direct disk-to-disk transfer but the result is probably the same.

If you really want a clone, instead of Restore From TM Backup, you can select Disk Utility and use its Restore function.
