Be sure to archive the conf files as well as the full source for Bacula with
each major archive that you do.

1. You might want to use two different databases, one for regular backups and
one for archives. This will clearly separate your archive data from your
regular data.
2. You might want to define two separate jobs/clients for each job to be
archived. One uses the normal backup database and retention periods. The
other uses the archive database and has appropriate archival retention
periods -- why not 30 years in the beginning if you don't do archives very
often; you can always reduce it later if your archive database grows too
large.
