Except for zpaq, there don't appear to be any backup tools in (gnu
packages compression).  There are no rust compression things in
(gnu packages compression) (yet!).   But yes, there's some opportunity
for abuse here.  There _are_ archival tools in (gnu packages
compression), e.g. tar and unzip.   Moving them to (gnu packages
backup) wouldn't bring any benefit though, since they are used by
practically everything.

Anyway, I'll continue trying to break cycles ...

Greetings,
Maxime.
