Duplicity Stable release 0.6.16 / October 15, 2011 Operating system Cross-platform (POSIX) Type Backup software License GNU General Public License Website http://duplicity.nongnu.org/ Duplicity is a software suite that provides easy encrypted, digitally signed, versioned, remote backup of files requiring little of the remote server.[1] It is capable of both full backups and incremental backups where only changes since the prior backup was made are stored. Chains consisting of a full backup and a series of incremental backups can be recovered to the point in time that any of the incremental steps were taken at. If any of the incremental backups are missing then the incremental backups following it cannot be reconstructed. It does this using GnuPG, librsync, tar, and rdiff.[1] To transmit data it can use SSH/SCP, local file access, rsync, FTP, and Amazon S3.[2]
Released under the terms of the GNU General Public License (GPL), Duplicity is free software.
Duplicity works best under Unix-like operating systems (such as Linux, BSD, and Mac OS X),[3] though it can be used with Windows under Cygwin. Currently duplicity supports deleted files, full Unix permissions, directories, and symbolic links, fifos, and device files, but not hard links.
