- the CGI stub, such as cgi-bin/fom.cgi. This captures any
    local configuration you had to do to get it working.

  - the fom-serve/ directory. You don't actually need the cache/
    subdirectory, but item/ and bags/ contain your original data.

  - the fom-meta/ directory. This directory has all of the
    configuration of your FAQ, user accounts, and that sort of
    metadata.

Here are the things to watch out for:

  - You may need to manually modify the CGI stub so it can find Perl,
  the FAQ::Omatic libraries, and the meta directory, if any of those
  moved on the new machine.

  - Be careful about the file ownership and permissions on what you
  reinstall. If you use tar, be sure to use the --preserve-permissions
  (-p) flag.

  fom-meta/ and fom-serve/ should both be owned by the user that runs CGI
  scripts on the new machine, in case that changed from the old one (e.g.
  'nobody' to 'apache'.) If you don't run the server you're restoring to,
  you'll either need the superuser's help to fix the ownership, or
  you'll need to write a little stub CGI to unpack the backup archive
  so that it writes the files out with the right ownership.

  - After you've restored, go back to the install page and through each
  of the steps again (even though they're already checked off). In
  particular, you want to ensure that Define Configuration Parameters is
  right for the new machine. And you'll want to rebuild the cache, since
  the embedded links in cached files may be different in the new
  environment.

If you move to another system, you may have problems with the RCS directories. I just deleted the RCS files, but I didn't need to preserve the history of the entries either.
