lscr.io/linuxserver/duplicatiWhat is docker-duplicati?
This LinuxServer.io image packages the Duplicati backup client so the whole service can run on your own hardware. Backups leave your machine encrypted, shrunk and changed-only, whether they land on disks you attach, a remote file server, or vendor object and drive storage such as S3, OneDrive, Google Drive, box.com, Mega and B2; FTP, SSH and WebDAV targets work too. Everything is wired up at container start through environment variables (user and group mapping, timezone, a key protecting the settings database, an optional web interface password, extra command-line arguments) plus three volumes: /config, /backups for local destinations and /source for the data being protected. Day-to-day use happens in a browser on port 8200. Images cover x86-64 and arm64; latest follows stable Duplicati releases while development tracks betas. Upgrading means pulling a fresh image and recreating the container, with your settings surviving as long as /config is host-mapped.
