New question #209976 on Duplicity:
https://answers.launchpad.net/duplicity/+question/209976

Hello,

I am using duplicity 0.6.19 and Python 2.7.3.

I interrupted a 2 TB initial backup to set a upload speed limit. So I used:

duplicity --no-encryption --volsize 1000 --asynchronous-upload --ssh-backend pexpect --scp-command "scp -l 10000" /directory ssh://user@server/directory

The first thing I noticed was, that the speed limit of 10000 KBit/s was not used. 

Secondly after some hours the backup process crashed with the following output:

Local and Remote metadata are synchronized, no sync needed.
Last full backup left a partial set, restarting.
Last full backup date: Thu Sep 27 13:23:30 2012
RESTART: Volumes 90 to 90 failed to upload before termination.
         Restarting backup at volume 90.
Restarting after volume 89, file path_to_file.jpg, block 0
File file path_to_file.jpg complete in backup set.
Continuing restart on file file path_to_file.jpg.

Maybe it is worth to do two different bugreports an that topic.
