I mean it is probably the single biggest point of failure. You set it up, walk away (who wants to watch a backup copy? Up there with watching paint dry and grass grow…)
It ought to be very simple to poll the image target drive for FILESYSTEM information and critical stop if FAT is detected so as to not waste my time.
Okay, okay, this is just a lot of venting… Sorry gang, I’m just upset that now I have to find or buy ANOTHER bloody external so I can run the backup before I send my MacBook in for service.
