Actually we were talking about a good bare-metal system recovery procedure
(with dump/restore or dd or ghost). Not about the most-up-to-date backup. I
will not make an image of my hard drive every night. In fact I make 2 kinds
of backups:
* dumps of filesystems (for long-term archiving)
* nightly tar backups of userfiles (tar for cross platform portability)
The dumps are not as frequent as the userfiles-backups. When updates are
applied or new applications are installed, a new dump will be done (and
archived, next to the old one).

If speed of recovery is more important than off-site archiving, you are
totally right! Personally, I prefer my archives on tape because a tape is
less expensive and more reliable for that purpose.
If you use the combined strategie (hdd frequent backups + Tape for
archiving) it is a good solution.
YMMV

I agree
