Accessible via Tools->Options->CD or DVD
Engine
Use primary burning engine - Selected by default. Backup4all uses an internal burning engine to write CDs or DVDs. It has integrated two burning engines in case that one of them does not recognize your burner. If your CD or DVD burner is recognized and you have no problem at all backing up to CD or DVD then you don't have to change this option.
| • | Use Native Win32 Interface (SPTI) - If checked Backup4all will use the SCSI Path-through interface (SPTI) available in Windows to communicate with the optical unit, and not the ASPI layer. By default this option is checked and it's available only when Use primary burning engine is selected. |
Use secondary burning engine - If you have problems backing up to CD or DVD or your burner is not recognized when using the primary burning engine, select this option to make Backup4all switch to the secondary integrated burning engine. Also, if you are making mirror backups, it is recommended to choose this secondary burning engine even if the burner is recognized when using primary burning engine (speeds up the backup process, but only for mirror backups).
| • | Burn CDs or DVDs using internal ASPI - If checked Backup4all will use its own, built-in ASPI layer to burn CDs or DVDs. If not checked, it will use the ASPI layer from the system32 folder of Windows (WNASPI.dll). If you experience problems writing to CD or DVD and these were not solved when switching from the primary burning engine to the secondary one, you should check this option. By default this option is checked and it's available only when Use secondary burning engine is selected. |
| • | External ASPI path - Usually the ASPI layer is located in C:\WINNT\system32\. If it's located in a different directory use the Browse  option to select it. |

If checked, the CD or DVD media is loaded before the execution of a backup. This option is useful when the CD or DVD was previously ejected by another process.
Eject CD or DVD after backup
If checked, the CD or DVD media is ejected, but not reloaded after burning process is finished. By default this option is not checked.
