Hi Deborah,

The latest version of the plugin (which requires at least version 2.60 of CMS Builder) runs every hour via the cron system, and doesn't require the admin to visit the CMS  for the backup to happen. 

But version 1.03 of the plugin and all previous versions check if a backup needs making when an admin visits the CMS or there is a visitor to the site. 

Let me know if you have any other questions. 

Cheers,

Greg
