I think duplicity supposes that the 'backup side' has no chance of executing
anything, and so the client only uses put/get operations to the backup end.

Maybe you should could use a full backup, then incremental backups, and never do
a full backup anymore. Depending on how your amount of data increases, it may be
an acceptable solution.

In any case, we are facing a situation like yours, and if someone has a better
solution than what I've said, I'd like to hear about it.
