I can't find the help file or other information.
What differences between incremental and differential mode?
Thanks

Hello!

It's explained in the help file:

Incremental - The program will check if the source has been changed from the last backup. If there is no need to copy the file, it will be skipped, saving backup time. The incremental procedure checks the Archive bit attribute of the file. You may want to manually reset the attribute to force a full backup: use the "Set the archive attributes" on the Task menu.

Differential: The program will check if the source has been changed from the last FULL backup. If there is no need to copy the file, it will be skipped, saving backup time. The differential procedure checks the Archive bit attribute of the file. You may want to manually reset the attribute to force a full backup: use the "Set the archive attributes" on the Task menu.

So differential backups are in fact redundanct.
