I'm not entirely sure if I understand your scenario correctly. Is the
database running at your customer site or are you acting as a service
provider and the customers are connecting via e.g. terminal services or
similar? How is bandwidth related to backup here?

If possible, I would always be in favor for gbak over nbackup due to its
logical data processing approach, thus detecting data corruption etc.
How large are your databases?
