How to use Postgresus with Cloudflare R2?
To obtain the credentials and endpoint for using your R2 bucket as an S3-compatible source, you'll need to:
1 Fill your bucket name
Enter your R2 bucket name in the storage configuration.
2 Set the region
In region field, fill
"auto"
3 Generate an Access Key ID & Secret Access Key
In the Cloudflare dashboard, go to R2 → API → Manage API Tokens. Create the token.
Grant it the permissions you need (e.g. "Object Read & Write").
When the token is created you'll see:
- Access Key ID (the token's ID)
- Secret Access Key (the SHA-256 hash of the token value)
Copy both now to Postgresus.
4 Find your Account ID
On any R2 page in the dashboard, you'll see your Account ID near the top (or in your account settings).
5 Construct the S3 endpoint
https://<ACCOUNT_ID>.r2.cloudflarestorage.com
Replace
<ACCOUNT_ID> with
the value from your dashboard.
Fill it to Postgresus as well.
🎉 Configuration Complete!
Now you have all fields filled and your Postgresus is ready to use Cloudflare R2 as storage for your PostgreSQL backups.
