Connect Your Own Cloudflare R2 Storage to DDA


This method allows you to connect your own storage server to DDA so that you are in control of your own storage and bandwidth. Doing this allows you to pay for your own storage via your Cloudflare account.

Cloudflare also doesn’t charge for bandwidth usage, so you can deliver many terabytes to your customers at no extra cost.

1. Sign up to Cloudflare R2

Alles, was Sie tun müssen, ist:

  1. Go to
  2. In the left navigation, go to “R2”
  3. Add your payment details

2. Create a bucket


3. Specify jurisdiction

We will want to specify a jurisdiction so that we know what the “Region” is. We will need to enter this into DDA later in this tutorial. Just remember where you set it to.

In this guide, we are using the EU.

Click “Create bucket” once you have set it.

4. In your bucket, click Settings

Go to your “Settings” for the bucket. Here is where we are going to paste some things into DDA.


4.1 Copy the URL from “Bucket details”

Copy the URL without the bucket name so that we can paste it to DDA in the “Endpoint” box.


Go to DDA > Settings > Configure custom S3. Paste the URL to DDA’s “Endpoint” box (without the bucket name at the end of the URL).
