As of version 4.6 of Liberty 4 the Backup Utility has under gone a major overhaul. A Schedule tab has been added to the utility. The items to be backed up and the location of where the backups will be saved are independent of the settings on the backup tab. A backup clean up has also been added to the Schedule tab. To configure automatic backups open the Liberty Backup and Restore Utility. Once the utility opens select the Schedule Tab.

Next select what items you want to backup.

Set what days and time you want the backup utility to run and then set the location you want to back up to. Once done with the settings click on Create task.

Another option you might want to configure at the same time is the "Remove automatic backups". This option allows you to determine how many backups you want to keep either based on days or overall size of the backup files in the backup location.
