About

What Duplicati does

Duplicati is an open-source backup client that creates encrypted, incremental backups to local or cloud storage. It supports SFTP, WebDAV, S3/B2, AES-256 encryption, deduplication, scheduling, retention policies, version history, and a web UI for restores and management.

Install Flow

How to self-host Duplicati

Duplicati can be deployed with standard Docker Compose using the Yantr app catalog. This page collects the basic information searchers usually need first: what Duplicati does, which Docker image Yantr uses, default ports, dependencies, and where to find the original compose template.

If you searched for Duplicati Docker, Duplicati Docker Compose, or self-host Duplicati, this page is the direct landing page for that app in Yantr's catalog.

After deployment, Yantr also lets you publish additional ports later from the stack page using Docker-style syntax. Use mappings like 8080:8080 for a fixed host port or just 8080 to let Docker assign a random host port for container port 8080.

Use Cases

What people run it for

Automated encrypted backups of your server to local NAS or remote storage.

Backup to multiple destinations (local + cloud) for redundancy.

Restore specific files or entire backups on demand.

Use deduplication to minimize storage requirements.

Ports
