Hope this isn't too stupid a question:
I've run an rsync backup of my Mac to an external drive, and now I'm trying to prove to myself that my backup is capable of being externally booted in the case of disaster.
I reboot holding down the option key, and I select my external drive as the boot drive -- then the machine comes up and looks identical, regardless of which drive I boot from.
How do I know that it worked? df shows that both disks are mounted, but I don't see my external drive mounted as root -- isn't that bad?
I'm vewy confused... I need to get my OSX book back from my dogwalker dammit...
If you happen to have been here done that and can point me in the right direction, I would appreciate it
