AutoUpdater

This page describes the AutoUpdater tool in Duplicati

The AutoUpdater is intended to support automatic updating of Duplicati. In the current version, the name is a bit misleading as it only supports checking for a new version, it does not yet support actually installing a new version automatically.

The binary is called Duplicati.CommandLine.AutoUpdater.exe on Windows and duplicati-autoupdater on Linux and MacOS.

To use the AutoUpdater, simply invoke it from the commandline:

duplicati-autoupdater check

This will check if there is a newer version available and remote the running version number.

It is also possible to download an updated installer package:

duplicati-autoupdater download

The download feature checks what package Duplicati is current installed with, and then obtains the most recent URL for that package and downloads it the the current directory. This feature only works if the installed package can be determined and there is an updated package available. If not, the download page is reported to the terminal for manual download.

Environment variables

By default, Duplicati uses the domains updates.duplicati.com and alt.updates.duplicati.com to find updates. If you are running Duplicati within a controlled environment, you can use the environment variables to change where Duplicati is looking for the updates:

AUTOUPDATER_Duplicati_URLS=https://example.com/stable/latest.manifest

Duplicati will detect the /stable/ part of the url and replace with the channel the user has chosen.

It is also possible to set the channel with an environment variable:

AUTOUPDATER_Duplicati_CHANNEL=canary
