It works just a Per described. If your main mail host is down/off-line, your mail is delivered to your backup host, held, then delivered to the primary mail host once it comes back on line.
Without a backup, if your primary is off-line for more that 24 hours, most (no all) mail host will give up trying to deliver mail and just return an error to the sender.
Postfix's default is five days, I believe. I think that might be more typical than the 24hours. A backup mail server is quite easily set up - from memory: with postfix you take the vanilla opensuse config and add "permit_mx_backup" to "smtpd_recipient_restrictions" and change "inet_interfaces" to "all". Then you add your new backup server as an MX to your domain.
