  Description     : user-friendly remote, encrypted, incremental
backups; capable GUI via built-in local server

I have looked at most of the backup packages in Debian and duplicati has
a better combination ot features and ease-of-use, at least for personal
use. It can perform remote, encrypted, incremental backups over several
transports. It has a very capable GUI with well-designed configuration
options. It makes a pragmatic, simplifying default choice of largely
trusting the user's machine but not the remote host.

The built-in web server for configuration and administration is very
convenient (and excellent for remote administration using port forwarding).

A debian package exists and requires little more than automated
installation of systemd configuration.

I mentioned this RFP to the Duplicati issues just to centralise the
information. At this stage the project doesn't have the resources to
complete the packaging.

In a very very very quick overview, this project seems to have several
files without source code or licensing, and some conflicting licenses.
