what do you do when duplicity fails because your line chokes? Restart
the full? And if it chokes again? Restart again? Recent duplicity is
supposed to resume, but personally I wouldn't count on it for production
usage.
The local storage workaround results in duplicity quickly finishing
backups. This way you separate the backup creation from the upload
process. You separate it from the bottleneck that your line is.

This way you can in parallel to your ongoing new full upload, upload the much
smaller incremental backup of the old chain. They should be much smaller of
course, so they can be transferred within a day despite your other upload(s).
How much daily change do you generate?

Right. Duplicity looks what is latest in the repository and acts accordingly.
That's why i wrote 'new folder'. Reread my last comment ;).
A new folder is a new empty repository, hence the old backup chain in the old
repository can be incrementally extended as you like.

duply only simplifies duplicity. You can of course force duplicity to
full or incr (if a full already exists) without duply.

yes. Duplicity currently expects that there is only one instance running
per repository.
