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 2.1.0.106 release.

• STEP 1

Please Support My work by Making a Donation.

• STEP 2

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.

• STEP 4

Now create three new folders inside the duplicati folder that you have previously created at STEP 3 and name them backups, config, source. Follow the instructions in the image below.
Note: Be careful to enter only lowercase, not uppercase letters.

• STEP 5

Go to Control Panel / Task Scheduler / Create / Scheduled Task / User-defined script. Follow the instructions in the image below.

• STEP 6

Once you click on User-defined script, a new window will open. Follow the instructions below:

1. General: In the Task field type in Install Duplicati. Uncheck the “Enabled” option. Select root User.
2. Schedule: Select Run on the following date then select “Do not repeat“.
3. Task Settings: Check “Send run details by email“, add your email then copy paste the code below in the Run command area. After that, click OK.

docker run -d --name=duplicati \
-p 8200:8200 \
-e PUID=1026 \
-e PGID=100 \
-e TZ=Europe/Bucharest \
-e SETTINGS_ENCRYPTION_KEY=q9TAW5pK5O9DqAWhY18XupmtlZk0ULRmjroiZcfvJkvZduSYzrzc0FtM2yfHEeyB \
-e DUPLICATI__WEBSERVICE_PASSWORD=mariushosting \
-v /volume1/docker/duplicati/config:/config \
-v /volume1/docker/duplicati/backups:/backups \
-v /volume1/docker/duplicati/source:/source \
--restart always \
ghcr.io/linuxserver/duplicati

Note: Before you paste the code above in the Run command area below, change the value numbers for PUID and PGID with your own values. (Follow my step by step guide on how to do this.)
Note: Before you paste the code above in the Run command area below, change the value for TZ. (Select your current Time Zone from this list.)
Note: Before you paste the code above in the Run command area below, change the value for SETTINGS_ENCRYPTION_KEY. (Generate your own 64 length SETTINGS_ENCRYPTION_KEY.)
Note: Before you paste the code above in the Run command area below, change the value for DUPLICATI__WEBSERVICE_PASSWORD. Type in your own password. mariushosting is an example for a password.

• STEP 7

After you click OK on STEP 6 a new warning pop up window will open. Click OK.

After you click OK, type in your DSM Password then click Submit. Follow the instructions in the image below.

• STEP 8

After you click Submit on STEP 7, select your “Install Duplicati” Task then click the “Run” tab. You will be asked to run Install Duplicati – click OK. Follow the instructions in the image below.

• STEP 9

🟢Please Support My work by Making a Donation. Almost 99,9% of the people that install something using my guides forget to support my work, or just ignore STEP 1. I’ve been very honest about this aspect of my work since the beginning: I don’t run any ADS, I don’t require subscriptions, paid or otherwise, I don’t collect IPs, emails, and I don’t have any referral links from Amazon or other merchants. I also don’t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. It’s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.

• STEP 10

The installation process can take up to a few seconds/minutes. It will depend on your Internet speed connection. Now open your browser and type in http://Synology-ip-address:8200/login.html You will be prompted to enter your password (DUPLICATI__WEBSERVICE_PASSWORD) that you have previously added at STEP 6. Click Sign In. Follow the instructions in the image below.

• STEP 11
