How do I install an older version of Server Backup Manager for vulnerability testing, and what initial configuration is needed?

To install an older version, download the package from http://r1soft.mirror.iweb.ca/repo.r1soft.com/release/6.2.2/78/trials/R1soft-ServerBackup-Manager-SE-linux64-6-2-2.zip, extract it, and install the `.deb` files with `dpkg -i *.deb`. Then configure the admin user and ports using `serverbackup-setup --user admin --pass 123456` and `serverbackup-setup --http-port 8080 --https-port 8443`, finally start the service with `/etc/init.d/cdp-server restart`. For detailed steps, see the Server Backup Manager Vulnerability Debugging Environment Setup article.
