When the Backup Options Tool is clicked, a pop up will appear on your screen. Here you can edit the standard backup options, as well as, the nightly backup options.  When you have finished editing, the backup options click the save button
NOTE: As of 8/1/2021 ACP will create full and incremental backups automatically regardless of what the default nightly backup type is. This option is now ignored by the system. The feature is currently under evaluation to be removed from the portal.
