How odd.  I've never seen a situation this.
I also don't understand how a file system using Unix semantics could
hard link between different filesystems (let alone different hard disks).
Or how deleting one hard link would affect another hard link.
(Changing the contents I could understand.)

Personally I would turn no_create_root on (after your first backup). 
But it won't help with this problem.

If you don't get any better suggestions, you could try turning off
link_dest.  I'm not sure whether turning it off would help, but it is
something you could experiment with, if you're into experimentation.
 
You could send some more information to the list, like the output
of these commands:
	mount
	df /private/etc /Volumes/mirror/backup/daily.0/private/etc
	ls -li /private/etc/hosts 
	ls -li /Volumes/mirror/backup/daily.0/private/etc/hosts
	tail -20 /var/log/rsnapshot

I'm assuming you have a file called /private/etc/hosts.
If not, please substitute some other regular file that exists.
