"Duplicity backs directories by producing encrypted tar-format volumes
and uploading them to a remote or local file server. Because duplicity
uses librsync, the incremental archives are space efficient and only
record the parts of files that have changed since the last backup.
Because duplicity uses GnuPG to encrypt and/or sign these archives, they
will be safe from spying and/or modification by the server... In theory
many protocols for connecting to a file server could be supported; so
far ssh/scp, local file access, rsync, ftp, HSI, WebDAV, and Amazon S3
have been written."
