(I should really be replying to the OP, but ..)

Of course, the -sensible- method of doing it is to cycle through backup media,
rather than having an "active" and "backup" disk set. All you need is one bad
backup and everything is toast - or, in my case (which didn't hurt me as I
-have- lots of backup disks that I swap in once a week into my enclosure, as
well as hourly/daily/weekly incremental tarballs going off-site) lightning
damaged the fileserver and the currently active full backup going to the external
disk. Both were very charcoalled :)

(Yet another problem solved thirty years ago that people keep reinventing..)
