On the other hand, if you have a predictable churn of high performance
production boxes being replaced every few years, tossing a few new big
cheap drives into a still nice but retired server and starting over is
a very attractive option.  You don't need to migrate anything - just
keep the old box around until the replacement has the history you need
to keep.

Use a good centralized backup platform such as netbackup, networker, etc. The investment made in backup is an investment in the business' future.

There's a place for those, but probably not for someone who doesn't
even want to buy new drives.
