First we suppose that you dedicate a directory to your MondoRescue mirror. Adapt to your taste/needs:

# mkdir -p /prj/ftp /prj/www

Then populate the content from the master MondoRescue server:

# cat > /usr/local/bin/mirror-mondo << EOF
rsync -av rsync.mondorescue.org::mondorescue-ftp /prj/ftp
rsync -av rsync.mondorescue.org::mondorescue-www /prj/www
EOF
# chmod 755 /usr/local/bin/mirror-mondo
# /usr/local/bin/mirror-mondo

Do that regularly (daily basis is preferred) with the appropriate crontab setup:

# cat >> /var/spool/cron/root << EOF
0 12 * * * /usr/local/bin/mirror-mondo
EOF

Once you get the content, setup your ftp and http servers to serve MondoRescue content (in my case vsftpd and apache):

# cat >> /etc/passwd << EOF
ftp:x:497:497:system user for vsftpd:/prj/ftp:/bin/false
ftpnobody:x:502:502::/var/empty:/sbin/nologin
EOF
# perl -pi -e 's/nopriv_user=.*/nopriv_user=ftpnobody/' /etc/vsftpd/vsftpd.conf
# perl -pi -e 's/ftp_username=.*/ftp_username=ftp/' /etc/vsftpd/vsftpd.conf
# /etc/init.d/vsftpd restart
# lftp localhost
lftp localhost:~> dir
