And a backup is not a copy?

A backup system has multiple copies, with historical content.

How do you come to that definition? A backup system has as many copies
as desired/needed by business practice. If one copy without history is
sufficient, then that's a good backup.

The basic reason is that problems can happen with "the copy". No matter
what your system, one copy is no copy at certain times.

As others have pointed out, it is the system, not the tools (tar, cpio,
rsync, etc).

As you say, it is about what he really needs.

My 2c is that depending on amount of data and frequency of changing, he
could probably just dump his databases and just burn a DVD each night.
$AUS50 for a dvd burner and AUS50c/DVD. Even cheap DVD should last a few
years before they are toasters.
