Config export and import

You can save your Plume settings to a JSON file and load them on another site. This is useful for staging copies, multisite networks and moving to a new server.

Export

1. Go to Media → Plume → Tools.
2. Under Configuration backup, select Download config.json.

The file is named like nimbus-config-20261103-091500.json.

{
  "version": "1.0",
  "plugin": "nimbus",
  "exported_at": "2026-11-03T09:15:00+00:00",
  "has_credentials": true,
  "settings": {
    "provider": "r2",
    "bucket": "my-media",
    "serve_from_storage": true
  }
}

The real file lists every exported key. has_credentials tells you whether keys are included.

What is included

The file holds the connection and delivery settings: provider, bucket, r2_account_id, region, access_key, secret_key, session_token, prefix, endpoint, use_path_style_endpoint, remove_local_copies, serve_from_storage, custom_domain and enabled.

It also holds the cache purge settings, including cloudflare_zone_id and cloudflare_api_token, the path filters, and offload_min_size_kb, offload_allowed_mime_types, storage_class, visibility and delete_remote_on_wp_delete.

It does not include the off-hours batch settings or the logging settings.

Handle the file like a password

The export contains your access key, secret key and Cloudflare token as plain text. Do not commit it to a repository, attach it to a ticket, or leave it in a shared folder. Delete it after use. If it leaks, rotate the keys at your provider.

Import

1. Go to Media → Plume → Tools → Configuration backup.
2. Choose a .json file and select Import.
3. Check the settings, then save if you want to change anything.

Rules:

• The file must be .json and no larger than 512 KB.
• It must contain "plugin": "nimbus".
• Only known setting keys are read. Others are ignored.
• The import replaces the current settings straight away. Plume reports “Configuration imported successfully. Review the settings below and save if needed.”

The first step of the setup wizard also accepts a config file to fill in the form.

Tip: On a staging site, import the file, then run Test Connection before you turn anything on.
