Well, given that a "proper" backup scheme involves
daily, weekly, monthly and yearly backups (though
the latter two are mostly for archival purposes, not
for restoration of the system), you really have to
have problems for the backups to be useless.
Then again, that sortof thing was overkill for most
home systems.

No, I'm saying that since "copy" is in internal
function of command.com, you can't use the dodge
that we used with the *external* format program.
The dodge worked because we could rename FORMAT.COm
to something else and create a FORMAT.BAT.
Doing that with COPY requires (if you are lucky)
using a hex editor to patch COMMAND.COM
Somebody posting something about a COPYCMD
environment variable. No oidea how (or *if*) it
works in DR-dOs.
