BackupBuddy also allows you to create schedules for when backups should be created and where they should be sent to. This feature helps to create a consistent amount of time between each backup without having to remember to login and create the backup.
How Backup Schedules Work
Schedules are inserted into the WordPress cron system and are executed once by the WordPress actions core at a time which you specify. The action will fire off when someone visits your WordPress site, if the schedule time has passed. A scheduled action cannot occur until someone visits after the scheduled time has passed.
