I just tested this, backed up a library that is about 150 MB and it uploaded the backup file to Dropbox in about 12 seconds. So I have no idea why it's taking 8 minutes to upload an 8.4 MB file for you. Is there a reason you can't use a web browser to access Dropbox on your Windows tablet? That should work just as well for accessing Dropbox. I would like to figure out why the upload is so slow for you though.
