And comodo again copied all files not only changed or new...
The fact that CB says "Processing item #####" doesn't mean that the item is copied again from source to destination.
You can verify this by observing the time difference between a full and an incremental backup.
I know the logging doesn't show any difference between full and incremental backups but this will be fixed in an update.
Edit: There is an issue with scheduled simple copy incremental not working properly in build 96. An update will soon be available.
