It seems odd for a private 192.168.x.x IP to be visible remotely
instead of hidden by intermediate NAT routers.

Did you restart apache after the config change?  Also, if you are
running apache 2.2 it would be the 'Allow From' syntax.

For 'one-off' remote access, you might use ssh port forwarding
instead.   Something like ssh -L8080:target_host:80 target_host from
your client host (putty or cygwin ssh can do this from windows) will
set up an encrypted tunnel as long as the connection is open so you
can open a browser to http://localhost:8080 which is tunneled to the
target's port 80 - and will appear to have also originated from that
host.   For even more generic remote access you can run 'x2go' at both
ends (clients are cross platform) which does its own ssh tunnel and
gives pretty good remote GUI access so you could run the browser on
the backuppc host with remote access.

It's not necessary to use these approaches since you should be able to
configure apache to allow access, but sometimes they are better or
more secure than opening up access to apache directly.
