概要
Bandwidth-efficient encrypted backup
履歴
duplicity is a long-running encrypted, bandwidth-efficient backup tool. It backs up directories by creating encrypted tar-format volumes and uploading them to local or remote storage, using librsync so incrementals record only changed parts of files.
duplicity's public identity has stayed remarkably stable: encrypted remote backups built from tar, GnuPG, and the rsync algorithm. The official site describes this design directly and notes that the package also includes `rdiffdir`, an extension of librsync's `rdiff` idea to directories.
The project later moved its public development to GitLab, where the repository metadata records the current project namespace as created in 2019. The official site still links to older Launchpad downloads for historical releases, showing a longer project history than the GitLab creation date alone.
By 2026 duplicity had reached the 3.x series, with the official site listing 3.1.0 as the current release on June 16, 2026. The stable README also reflects modern Python packaging changes, recommending pipx/venv-style installs for Python 3.11-era externally managed environments.
duplicity's adoption rests on a simple Unix promise: encrypted incremental backups to many storage protocols from a CLI. The official site says it is mature software used for large personal and corporate backups.
The project is packaged broadly across Homebrew, Alpine, Debian, Fedora, MacPorts, Nix, Arch, Ubuntu, and openSUSE-style ecosystems in the batch metadata. The official site also names Fedora, Debian, and Ubuntu distribution inclusion, reinforcing its long-standing Linux distribution presence.
Its ecosystem includes frontends such as Déjà Dup and duply. The official duplicity homepage points to Déjà Dup releases and describes duply as a shell frontend formerly known as ftplicity.
Typical usage is to run duplicity against a source directory and a target URL, using GnuPG keys or passphrases for encryption/signing and a backend URL for storage. Supported backends listed by the official site include S3, Backblaze B2, Dropbox, FTP, GIO, Google Drive, IMAP, local filesystem, Mega, Azure, OneDrive, rclone, rsync, SSH/SCP, SwiftStack, Tahoe-LAFS, and WebDAV.
duplicity supports deleted files, Unix permissions, directories, symbolic links, FIFOs, and device files, but the official site notes hard links are not supported. Administrators often wrap it in cron jobs, system scripts, duply profiles, or GUI frontends.
duplicity matters to package maintainers because it is old, security-sensitive infrastructure at the intersection of Python packaging, GnuPG, librsync, remote-storage SDKs, and system backup policy.
It also anchors a family of related packages. Duplicacy's README compares itself directly with duplicity, and duply exists primarily to profile and automate duplicity invocations. That makes duplicity both an executable and a reference point in backup-tool design debates.
