Instructions for mirrors
------------------------
6 August 1995, Nicolas Pioch <pioch@email.enst.fr>

For the mirroring process, I suggest using the ftp-mirroring package
called "mirror.pl". The latest version should be available from:

        src.doc.ic.ac.uk [146.169.2.1]
                directory: computing/archiving/mirror
                (shortcut packages/mirror)

I tried version 2.3, which seems to be great... when it doesn't dump core :)


Mirror sites
------------

The WebMuseum can be mirrored from

  - ftp://sunsite.unc.edu/pub/multimedia/pictures/webmuseum/
  - ftp://sunsite.doc.ic.ac.uk/packages/wm/
  - ftp://sunsite.icm.edu.pl/www/wm/


Updating the mirror at least twice a week would be cool;
just add the mirror process in the crontab, usually between 2am and 6am.

See below for a sample mirror.defaults file.
I also suggest trying the mirror first on the subdirectory "/wm/rh/"
to check that everything works fine.

Files must appear as "/wm/..." under any HTTP tree.
Current size of the exhibit is around 130 Mb. Growth rate is small.

Let me know once you're ready so that I can add your site in the
list of the network. Please provide the URL of the mirror,
your internet connectivity and the policy/restriction of use
(for instance: Site for Irish users ONLY).

Thanks!

PS: Objects in a mirror are closer than you think!
