=E2=80=98nix-copy-closure=E2=80=99 can be thought of as an rsync for the st=
ore, built on
top of archives (archives in =E2=80=9Cnar=E2=80=9D format, as produced by =
=E2=80=98guix archive=E2=80=99
and other tools.)

We have that functionality in =E2=80=98guix offload=E2=80=99=C2=B9, which b=
asically works by
running =E2=80=98guix archive --missing=E2=80=99 on the remote machine, but=
 I think it
would be nice to have a standalone =E2=80=98guix copy=E2=80=99 command base=
d on
Guile-SSH.
