Duplicity was written by Ben Escoto. Feel free to send bug reports or questions to bescoto@stanford.edu, but you may prefer the Mailing list.

It contains some code packages written by other authors:

tarfile.py by Lars Gustabel - Python module for reading/writing tar files.
GnuPGInterface.py by Frank J. Tobin - Python interface to GnuPG

Thanks to:

The Free Software Foundation, for hosting duplicity with their Savannah system.
Mikael moshir for sending his interesting paper on encrypted backup with the rsync algorithm. Duplicity didn't end up using his scheme, not because it wasn't very good, but so volumes could remain processable with, for instance, rdiff.
Peter Ehrenberg for many helpful comments/bug reports.
