task schedule problem.....

I would like to schedule automatic backups every day. I did everything, just that I have the problem that I automatically creates a backup file name. how can I do? I follow this guide:

Open Acronis True Image Create and Configure Backup Locations Create backup location Create a folder where to place the backup Remove the tick size to share location and day storage limit Choose the number of backups
Now we go to backup plan Operations and then click Schedule Task Select My Computer Select the disk you want to create the backup Now we are going to choose backup locations and clickiamo and then the backup location created above Choose how to use, preferably full backups Set the options manually Set the priority if you want a fast backup with greater utilization of resources or a backup slow with less-exploitation; in additional setting, then go up the archive validation to select and deselect the other voice Set how often you want to backup, the time
