How to Install Duplicati on Your Synology NAS

Duplicati works with standard protocols like FTP, SSH, WebDAV as well as popular services like Microsoft OneDrive, Amazon Cloud Drive & S3, Google Drive, box, Mega, hubiC and many others. In this step by step guide I will show you how to install Duplicati on your Synology NAS using Docker.

💡Note: This guide works perfectly with the latest Duplicati 2.1.0.100 release.

Install Container Manager via Synology “Package Center”. If you run an older DSM version (under 7.2), search for Docker instead of Container Manager.

  • STEP 3

Go to File Station and open the docker folder. Inside the docker folder, create one new folder and name it duplicati. Follow the instructions in the image below.
Note: Be careful to enter only lowercase, not uppercase letters.
