That's the membership subscription: unlimited backups to local and remote (meaning "peer" or other computers) destinations, automatic software updates, and for as many devices as you have. Some backup services (especially those with unlimited offerings) limit you to just one or two computers. And your membership subscription can become free if you refer others each year (they also get a discount). 3 referrals per year will keep your membership totally free.
