Encrypted bandwidth-efficient backup using the rsync algorithm

What is it?

Duplicity backs directories by producing encrypted tar-formatvolumes and uploading them to a remote or local file server. Becauseduplicity useslibrsync, theincremental archives are space efficient and only record the parts offiles that have changed since the last backup. Because duplicity usesGnuPG to encrypt and/or sign thesearchives, they will be safe from spying and/or modification by theserver.

The duplicity package also includes the rdiffdirutility. Rdiffdir is an extension of librsync'srdiff to directories---it can be used to producesignatures and deltas of directories as well as regular files. Thesesignatures and deltas are in GNU tar format.
