If Fbackup freeware does not allow for multiple versions of the backup job, why do you have the predefined Advanced option at Run Action Before Backup to "clear old backup" and "abort action when action fails". I believe I understand what the true intent of this is - to not "overwrite" the single version save that Fbackup allows as opposed to multiple saved backups in the Backup4All commercial package.
However this terminology does lead one to believe that there are multiple versions saved. Perhaps a notice about this could be added to the display if /when this option is checked off???
