the purge would either fail or succeed, but in reality not have done anything
depending of the implementation in the backend code. either way not an issue
according to your write only strategy.

be aware of interrupted uploads. currently duplicity might try to resume a
backu0p and in turn overwrite a volume on the backend, which would defeat your
purpose.
Ken: what does happen if the upload part during a resumed backup fails? would
duplicity fail but try resuming again on the next run?
