Hi

I'm trying to backup ~600Gb using the dropbox backend, and in 24 hours only 100Gb has been uploaded.

1. Is there anything I can do to make this go faster?
2. And will the next full backup take as long?

Some info about my setup:
- 50/50Mbit internet connection
- i3-4130T CPU @ 2.90GHz
- 8Gb Ram
- Data that is backed up is on a raid5 array
- archive-dir is on a SSD
- tempdir is on tmpfs
- system load is minimal, load average: 0,02, 0,08, 0,12
