Restoring Server from Bakcup

HI everybody;

I have read the document regarding backups, but we are doing backups using bacula/bareos periodically. Now i’m facing the situation that some virtualmin/webmin files get corrupted (after upgrading webmin/virtualmin) and the only way to recover the server is to restores those files/folders. We have made some successful test restoring folders like /var/webmin, /etc/webmin and /usr/libexec/webmin. As I know, virtualmin store some configuration, like autoreply settings in its directories. Can you tell me which folder/files should I skip during the restore process so this configuration may not be overwriten during the restore process?

Thanks in advance
