I use a software called Paperport (scanning software) and I use it to run a paperless business. In other words I have a ton of files that I want to backup regularly. I can understand the first backup taking 30 minutes or so but what I don't understand is if I go to back up the next day and only have one or two new scans it still takes 30 minutes. Is there something I can do to just back up the "new" scans only. Thank you. Frank
