Quick question about duplicity.   Does it have to d/l the previous
backups to determine the incremental changes?   For instance, if I run
"duplicity /var/log s3://host/bucket/", once it does the initial full
backup (which could be GBs) what does it do to determine what to build
the incremental list from next time it runs?

Thanks!
