I rather doubt that Dave Decot is living *that* far in the past :-)

Seriously, a better interpretation is:  `Have spares.  Use them.'
Keeping one spare drive, to be used as a replacement when one fails,
and to be used to store data that are being moved temporarily, is quite
reasonable.  Modern SCSI disks are cheap enough ($3800 for 1.2 GB) and
reliable enough to buy a baker's dozen, use 12, and keep one as the
replacement for whichever fails first.  Instead of paying for
maintenance, reassign the disk maintenance budget into the new-spares
budget.  When one *does* fail, slap in the spare and buy a new spare.

(Determining the appropriate ratio of spares-to-drives-in-use is what
administrative types are supposedly being paid for :-) )
