That's not how this failure mode works, though it is certainly safer
with it's own supply. Well, safer from the computer's power supply but
of course more vulnerable to the arguably more variable mains power
supply. And of course - plug-pack power supplies fail too.

Our points boil down to this: Just because nothing bad has happened to
your backup drive yet does not mean it never will.

The whole point of a backup is to protect you against the unexpected,
the unusual, and the unfortunate. Your backup system does not do that.

It's fine if you want to do it that way. All we are trying to
communicate is that it is a bad idea, and others should not emulate you
if they value their data.
