Cloudflare R2

Create the account and enable R2

1. Sign up at dash.cloudflare.com and verify the email address.
2. In the left menu open R2 Object Storage. The first time, Cloudflare asks for a payment method and to accept the R2 terms; nothing is charged inside the free allowance.

Find your account id

R2's endpoint is built from your account id rather than a region.

1. On the R2 overview page, the Account ID is shown on the right, with a copy button. It is also the long hexadecimal segment in the dashboard URL.
2. Copy it; SimDrive asks for it.

Create a bucket

1. Click Create bucket, give it a name, and leave the location on Automatic.
2. Click Create bucket.

Create an API token

R2 has its own tokens, separate from the account-wide API tokens.

1. On the R2 overview page, click Manage R2 API Tokens (under the account id), then Create API token.
2. Name it after the machine.
3. Permissions: Object Read & Write.
4. Specify bucket(s): choose the bucket you created, so the token can touch nothing else.
5. Leave the TTL on Forever unless you want the token to expire.
6. Click Create API Token. The page shows a Token value, an Access Key ID, a Secret Access Key and the endpoint for S3 clients. SimDrive wants the Access Key ID and the Secret Access Key — not the token value. Copy them now; they are shown once.

A token limited to one bucket cannot list buckets, so SimDrive will ask you to type the bucket name. That is normal.

Enter it in SimDrive

1. Settings → Storage → Connect storage → Cloudflare R2.
2. Account id: the value from the R2 overview page.
3. Access Key ID and Secret Access Key: from the token page.
4. There is no region to choose; SimDrive uses "auto", which is what R2 expects.
5. Click Connect, then Choose folders to back up.
