It doesnt really make a lot of sense to clone for backup like that.

It makes a lot more sense to backup instead of clone, both
because of that is much quicker than cloning with incremental
backups and because you dont have this problem with the
first boot of the clone after the clone has been done.

> and that both HDDs undergone their virgin booting.

You've mangled that considerably. The only time that virgin booting
config matters is when booting the clone. You dont actually boot the
clone if you are cloning for backujp, you just keep booting the source.

When you boot the source, it doesnt matter that the clone is visible
at the time the source is booted after the clone has been done.

The only thing you have to be careful about is booting the
clone for the first time with the source visible to the clone.

No, there is never a problem with booting the source. The problem
only every arises when booting the clone for the first time. When
you boot  the clone for the first time, the source must not be visible.

Likely there is, but I havent looked for one.

It isnt actually.

I havent had a look at what is available.

No problem.
