The corresponding scripts are not included in coser installer for
brevity and because we do not have time to evaluate/maintain them.
Coser is a means to easily install servers, which are just a part of
the infrastructure. The site-specific arrangements including backup
are left out.

You may have to take the scripts from upstream Coda distribution and/or
rewrite.
