ResolutionUnfortunately it is impossible with the current version of Backup Utilities. However, you can use a little "trick":
1) Run 'Plesk Backup' and create a 'Scheduled Backup'. Set all necessary settings for this backup task.
2) The configuration of scheduled backup will be saved into file
3) To use this configuration file run the following command from the command line:
%plesk_bin%\backup.exe --config-file %plesk_dir%\backup\backup_schedule.psc
Plesk backup will be run in background mode.
