Duplicity is a commandline program to backup your files to a local folder or remote server. It is extremely efficient, using rsync to store only the parts of files that have changed while still allowing you to restore files as at any date.

It supports storing your files on a large number of backends, including Amazon Drive, Azure, Dropbox, Google Docs, Google Drive, IMAP, Mega, OneDrive, rsync, SSH, Swift and WebDAV. The backup archives are encrypted and signed using GnuPG, protecting them from unauthorised access or modification.

NOTE: We provide amd64 in the edge and stable channels and additionally arm64, armhf, and ppc64 snaps. Only amd64 is actively tested and developed. Please let us know at https://gitlab.com/duplicity/duplicity/-/issues if you use the arm64, armhf, or ppc64 builds with success or failure.

Previous snap versions are archived on: https://sourceforge.net/projects/duplicity/files/snaps/

The command to install a manually downloaded snap file looks like snap install duplicity_1.x.x_amd64.snap --dangerous --classic. NOTE: these will not autoupgrade on new releases.
