I understand that Déjà-Dup ocassionally does full backups, so that a single corrupted backup in the chain will not invalidate all following backups. But since I am going to reinstall the system, I would like to have one final backup. Déjà-Dup says, that it is time for a full backup, which would be a waste of space in this case.
Question: Can I force Déjà-Dup to create only an incremental backup?
Edit: I have forgotten to mention, that déjà-dup is set up to backup two different folders
